Deep-Tech Maritime Startups: Legal Structure, Compliance & Funding

India’s maritime sector handles more than 95% of trade by volume across 7,500 kilometres of coastline, yet the technology layer on top of this infrastructure is only beginning to be built. A cluster of founders is now working on products that sit at the intersection of AI, robotics, advanced materials, and ocean systems: autonomous vessel guidance, subsea inspection drones, port logistics intelligence, and green propulsion stacks. These companies are not simply technology startups that happen to serve shipping customers. They are deep tech ventures operating inside one of India’s most heavily regulated sectors, which means compliance errors are not just expensive, they can structurally impair a funding round or a defence or port authority contract. This article maps the legal architecture a maritime deep tech founder needs to understand before their Series A, covering entity structure, DPIIT recognition, sector licensing, IP protection, FEMA and foreign investment, SCOMET dual-use controls, and the funding instruments that now exist specifically for this space.

What legal structure should a deep tech maritime startup use in India?

A private limited company incorporated under the Companies Act 2013 is the correct structure for a deep tech maritime startup in India. It is the only entity type that cleanly satisfies DPIIT recognition eligibility, allows ESOP issuance under Section 62(1)(b), accepts FDI under FEMA (Non-debt Instruments) Rules 2019, and supports IP assignment through founder assignment agreements. An LLP is technically eligible for DPIIT recognition under the 2026 framework but creates complications for foreign equity investment, ESOP design, and IMB certification under Section 80-IAC of the Income Tax Act 1961 (Section 140 of the Income Tax Act 2025 for FY 2026-27 onwards).

Why deep tech recognition under the 2026 DPIIT framework matters for maritime founders

The Department for Promotion of Industry and Internal Trade (DPIIT) issued Gazette Notification G.S.R. 108(E) on 04/02/2026, replacing the 2019 framework entirely. For the first time, the notification defines a “Deep Tech Startup” as a separate and formally recognised category.

A maritime startup qualifies as a deep tech startup if it is engaged in novel scientific or engineering innovation, carries significant R&D expenditure, owns meaningful intellectual property, and has a clear commercialisation plan. Subsea robotics, autonomous vessel navigation using LiDAR and computer vision, AI-based port congestion modelling, and hydrogen or ammonia propulsion systems all meet this threshold if the underlying technology is original and documented.

The practical differences between standard startup recognition and deep tech recognition are material:

Recognition benefits comparison

Parameter	Standard startup	Deep tech startup
Recognition period	10 years from incorporation	20 years from incorporation
DPIIT turnover ceiling	₹200 crore in any FY	₹300 crore in any FY
Section 80-IAC profit holiday	3 years out of first 10	3 years out of first 20
80-IAC turnover ceiling (separate)	₹100 crore in any FY	₹100 crore in any FY (unchanged)
Negative list on fund use	Applies throughout recognition	Applies throughout recognition
Additional documentation	Standard	R&D records, patent filing evidence, commercialisation plan

One distinction founders consistently conflate: the ₹300 crore ceiling in the DPIIT notification governs when a startup loses recognition status, not when it loses the tax holiday. The Section 80-IAC profit exemption has its own, separate turnover ceiling of ₹100 crore in any financial year, embedded in the Income Tax Act and not changed by the 2026 DPIIT notification. A maritime deep tech company that clears ₹100 crore in the year it first becomes profitable, which is plausible for a startup with a single large defence or port authority contract, loses the 80-IAC deduction for that year even though it retains full DPIIT recognition up to ₹300 crore. Planning the three-year exemption window around this threshold is a finance team decision, not a compliance formality. For the full four-attribute eligibility test and the fund restriction analysis specific to deep tech recognition, see Treelife’s detailed breakdown of DPIIT deep tech eligibility and taxation.

The 20-year recognition window is specifically designed for deep tech gestation cycles. A maritime propulsion startup or a subsea materials company may take 8 to 12 years to reach commercialisation. Under the 2019 framework, that company would have been approaching or past the end of its recognition period before its first real revenue contract. The 2026 framework corrects that.

Section 80-IAC (renumbered as Section 140 of the Income Tax Act 2025, applicable to filings for FY 2026-27 onwards) certification continues to be processed through the Inter-Ministerial Board (IMB), which now formally includes representatives from the Department of Biotechnology and the Department of Science and Technology alongside the DPIIT convenor. The application is filed after DPIIT recognition is granted. IMB certification unlocks the three-year profit tax exemption, which is material for capital-efficient deep tech companies where early profitability from defence or port authority contracts can be substantial.

The 2026 notification also introduces a “Relaxations and Modifications” clause allowing the government to tailor conditions for specific startup classes. This is directly relevant to maritime technology founders whose revenue may depend on multi-year government contracts that would technically breach the negative list on non-core investments if prize money or advance payments are treated as passive income.

What sector-specific licences and regulatory clearances does a maritime startup need?

The maritime sector underwent a comprehensive legislative overhaul in 2025. Three statutes came into force together and collectively define the operating environment for any startup building products or services in this space.

The Merchant Shipping Act 2025 (Act No. 24 of 2025, assented to 18/08/2025, in force 15/03/2026) replaced the 1958 Act and is now administered by the Directorate General of Maritime Administration (DGMA), which is itself being renamed from the Directorate General of Shipping (DGS) as part of the transition. The Coastal Shipping Act 2025 (No. 27 of 2025, a companion statute) governs vessels in coasting trade.

The key regulatory clearances a maritime deep tech startup may need, depending on product category:

• Vessel registration under the Merchant Shipping Act 2025 if the startup builds or operates any craft, including unmanned surface vessels (USVs) and autonomous underwater vehicles (AUVs).
• Coastal trade licence from the Director General of Maritime Administration for any vessel-based service operating between Indian ports. Indian-flagged vessel owners are exempt from the licence requirement under the Coastal Shipping Act 2025, but a startup operating foreign-built or chartered vessels needs one.
• Approval from the Indian Naval Hydrographic Office for bathymetric survey operations or subsea data collection within India’s Exclusive Economic Zone (EEZ) under the Territorial Waters, Continental Shelf, Exclusive Economic Zone and Other Maritime Zones Act 1976.
• Ports regulatory approvals under the Indian Ports Act 2025 (passed 12/08/2025) for any technology system deployed at major or non-major ports, including AI-based vessel traffic management, crane automation, or hazardous cargo identification systems.
• Directorate General of Civil Aviation (DGCA) type approval for maritime surveillance drones that operate in coastal or EEZ airspace, since airspace and maritime zone rules overlap at low altitudes near India’s coastline.

The Sagarmala Startup and Innovation Initiative (S2I2), launched on 19/03/2025 and implemented through the Maritime India Foundation under the Ministry of Ports, Shipping and Waterways (MoPSW), is a structured mechanism to connect maritime startups to port authority procurement. Maritime Innovation Hubs at IIT Madras, IIT Bombay, IIT Kharagpur and Indian Maritime University provide a pathway from prototype to port authority pilot. A startup that secures an S2I2 pilot has a procurement track that bypasses the standard L1 tender process for innovation-related procurement up to specified thresholds.

How should a deep tech maritime startup structure its IP?

Maritime technology IP is legally complex because it often covers physical systems, embedded software, control algorithms, and training data simultaneously. Each of these is protected differently under Indian law, and the failure to structure IP correctly before a funding round is one of the most common due diligence failures Treelife sees in this sector.

The Patents Act 1970 (as amended) protects novel, non-obvious, industrially applicable inventions. For a maritime deep tech startup, this includes propulsion mechanisms, sensor fusion architectures, hull materials, and navigation algorithms provided the algorithm is claimed as part of a system with a technical effect, not as a standalone method. The Indian Patent Office’s revised guidelines for Computer Related Inventions (July 2025) now provide greater clarity on how AI-integrated systems can be claimed, which is directly relevant to AI-driven vessel navigation or port scheduling systems.

Key IP structuring rules before the first funding round:

• All founders must sign IP assignment agreements transferring any pre-incorporation inventions to the company. This is non-negotiable for IMB certification and for investor due diligence.
• Patent applications should be filed before any public disclosure, including at academic conferences, maritime exhibitions, or pilot operator demonstrations. India operates on a first-to-file basis, not a first-to-invent basis.
• If the technology has defence applications (which most subsea sensing and autonomous navigation tech does), the startup must check whether the patent application requires permission from the Controller General of Patents before filing internationally under Section 39 of the Patents Act 1970.
• Trade secrets and know-how that cannot be patented (training datasets, calibration parameters, proprietary simulation environments) should be protected through employee and contractor non-disclosure agreements and documented as trade secrets in the company’s IP register.
• DPIIT recognition entitles a startup to a fast-track patent examination at a reduced official fee. The examination timeline through the fast-track route has been running at 12 to 18 months versus the standard 36 to 60 months.

The National IPR Policy 2016 also encourages industry-academia collaboration for IP commercialisation, which is relevant for maritime startups that emerge from IIT or IISc research. A technology licensing agreement or sponsored research agreement with the originating institution must be in place before the company claims the IP in investor documents.

What FEMA and FDI compliance framework applies to a maritime deep tech startup?

A maritime deep tech startup raising foreign capital operates under the Foreign Exchange Management Act (FEMA) 1999 and the Foreign Exchange Management (Non-debt Instruments) Rules 2019 (NDI Rules).

The maritime sector sits under the broader manufacturing and technology services categories for FDI purposes. 100% FDI under the automatic route is permitted for technology companies serving the maritime sector. However, if the startup involves port operations, vessel ownership, or defence-adjacent technologies, specific sectoral caps and approval requirements apply:

FDI route by activity type

Activity	FDI route	Cap
Maritime technology SaaS (port AI, vessel tracking)	Automatic	100%
Shipbuilding and ship repair	Automatic	100%
Port and harbour projects	Automatic	100%
Defence-adjacent technology (autonomous systems)	Automatic up to 74%; Government route above 74%	100% subject to security clearance
Coasting trade operations	Automatic	74%
Broadcasting/surveillance from maritime platforms	Varies	Sector-specific

For a startup raising from a foreign venture capital investor, the investment instrument matters. Compulsorily convertible preference shares (CCPS) and compulsorily convertible debentures (CCDs) are treated as equity under the NDI Rules and can be issued under the automatic route at a valuation determined by a SEBI-registered Category I Merchant Banker or a Chartered Accountant using a recognised valuation method. Optionally convertible instruments are treated as debt and fall under the External Commercial Borrowing (ECB) framework, which has restrictions on end-use, tenure, and all-in cost.

Post-investment reporting obligations under FEMA are time-critical:

• Form FC-GPR must be filed with the Reserve Bank of India (RBI) through the AD Category I bank within 30 days of allotment of shares to a foreign investor. Late filing attracts a penalty of up to 300% of the transaction amount under the compounding provisions of FEMA.
• Form FC-TRS is required within 60 days of transfer of shares between a resident and a non-resident.
• The Annual Return on Foreign Liabilities and Assets (FLA return) must be filed by 15 July of each year with the RBI’s Statistics and Information Management Department.

One practical gap in the 2026 DPIIT notification flagged by legal practitioners is that the NDI Rules have not yet been updated to explicitly recognise the new deep tech startup category as a distinct entity class for FDI purposes. This means a deep tech maritime startup LLP faces structural complications for foreign equity investment that a private limited company does not. Until the NDI Rules are amended, the private limited company structure removes this uncertainty entirely.

Transfer pricing for GIFT-IFSC IP holding structures

A maritime deep tech startup that routes foreign investment through a GIFT-IFSC fund management entity, or holds its core IP in an IFSCA-registered unit, and then licenses that IP to the Indian operating company creates a related-party transaction that is subject to transfer pricing under Section 92 of the Income Tax Act 1961. The royalty or licensing fee paid by the Indian OpCo to the IFSC entity must be at arm’s length, determined using one of the prescribed methods under Rule 10B of the Income Tax Rules 1962: comparable uncontrolled price, resale price, cost plus, profit split, or transactional net margin method. If the aggregate value of international transactions between the two related entities exceeds ₹1 crore in a financial year, the company must obtain a report in Form 3CEB from a Chartered Accountant and file it with the income tax return. This is a recurring annual obligation, not a one-time setup cost, and the documentation (a contemporaneous transfer pricing study justifying the royalty rate) must be prepared before the financial year end, not after a tax notice arrives. A startup that sets up the GIFT-IFSC structure without budgeting for transfer pricing compliance is creating a back-year liability that surfaces at the worst possible time, typically ahead of a Series B due diligence or an audit.

How does GST and customs duty apply to a maritime deep tech startup?

This is an area that standard startup compliance guides do not cover, and maritime technology creates classification problems that general technology companies do not face.

GST place of supply for maritime technology services

When a maritime deep tech startup supplies technology services, the place of supply rules under the Integrated Goods and Services Tax (IGST) Act 2017 determine whether the supply is taxable in India or qualifies as a zero-rated export. The default rule for services is that the place of supply follows the location of the recipient. But maritime services have specific overrides under Section 13 of the IGST Act that govern cross-border scenarios:

• Services supplied in relation to goods transported on a vessel, where the supplier and recipient are outside India, are treated as supplied at the destination of the goods. This affects startups offering at-sea cargo monitoring or condition-sensing services under contracts with foreign shipping companies.
• Services related to vessels themselves, including maintenance, inspection, and navigation system supply, where the vessel is in Indian territorial waters, are treated as supplied in India regardless of where the foreign customer is incorporated. A startup supplying AUV-based hull inspection services to a Panamanian-flagged vessel at Jawaharlal Nehru Port Trust has an Indian place of supply and must charge GST unless the customer is registered under IGST as an overseas entity entitled to a refund.
• Repair and maintenance of goods (which can include vessel components) temporarily brought into India attract an 18% GST rate under SAC 9987, but spare parts supplied during the repair attract the relevant goods rate separately.

Zero-rating applies where the startup exports services to a foreign recipient and the payment is received in convertible foreign exchange. For port AI systems supplied to foreign-flagged vessels on a subscription basis with payment in USD, the supply qualifies as an export of service under Section 2(6) of the IGST Act, is zero-rated, and the startup can claim a refund of input tax credit on inputs used to make those supplies.

Customs duty on hardware components

A maritime deep tech startup that imports sensors, acoustic transducers, AUV components, or specialised marine-grade electronics faces Basic Customs Duty under the Customs Tariff Act 1975. The classification of subsea electronics under the Harmonised System (HS) matters because the duty rate varies by chapter: Chapter 85 (electrical machinery and equipment) attracts different rates from Chapter 90 (optical, measuring, and precision instruments), and misclassification triggers duty shortfall demands with interest.

Project Imports under Customs Tariff Heading 9801 is worth evaluating for maritime startups that import equipment for a defined project (a port technology deployment, a vessel-integrated system). Goods imported as part of a single project can be assessed at a concessional rate of 7.5% basic customs duty under Heading 9801, significantly below the standard Chapter 85 or 90 rates, provided the importer obtains project registration from the Commissioner of Customs before the first import.

GST on R&D services from academic institutions

A maritime startup that pays IIT Madras or NIOT for sponsored research or testing services receives a supply of service that is taxable under GST. Research services from government educational institutions were exempt under Notification 12/2017-Central Tax (Rate), but that exemption applies only to research services supplied to other government bodies, not to private companies. A startup receiving testing or simulation services from an IIT lab must confirm the GST treatment with the institution before budgeting the engagement, as the 18% GST on a large tank testing contract is a material cost that affects the project economics.

Comparison: GST treatment by maritime tech activity

Activity	Supply type	GST rate	Zero-rated?
Port AI software subscription to Indian port authority	Service (SAC 9983)	18%	No
Port AI software subscription to foreign vessel operator, paid in USD	Export of service	0% (zero-rated)	Yes, with input credit refund
AUV hull inspection service at Indian port	Service (SAC 9987)	18%	No
Hardware (sensors, transducers) supplied to Indian port	Goods (HS Chapter 85/90)	18%	No
Hardware exported to foreign buyer	Export of goods	0%	Yes, with drawback/input credit
Sponsored research received from IIT	Input service (SAC 9981)	18%	Not applicable

This is the compliance area most maritime deep tech founders discover late, often at the term sheet stage when a foreign investor’s counsel conducts export control due diligence.

The Special Chemicals, Organisms, Materials, Equipment and Technologies (SCOMET) list under Appendix 3 of Schedule II of the India Trade Classification (ITC-HS) regulates the export of dual-use items: products, software, and technology that serve civilian purposes but also carry potential military or strategic applications. The Directorate General of Foreign Trade (DGFT) under the Ministry of Commerce and Industry administers export authorisations for most SCOMET categories.

A DGFT notification dated 23/09/2025 added Category 7 to the SCOMET list, effective 23/10/2025. Category 7 covers emerging technologies including quantum computing systems, advanced semiconductors, cryogenic systems, and additive manufacturing equipment used in metallurgy. For maritime deep tech startups, the relevant controls are in the existing marine, avionics, and propulsion categories, as well as the newly controlled underwater sensing and autonomous systems classifications.

A maritime deep tech startup should conduct a SCOMET classification analysis for any product or technology it intends to export, license to foreign parties, or transfer to a foreign employee or research collaborator. The relevant questions are:

• Does the technology involve acoustic sensors, sonar arrays, underwater navigation systems, or subsea communication protocols?
• Does the propulsion or power system use controlled materials (isotopically pure elements, high-energy density cells)?
• Does the autonomous control algorithm exceed certain performance thresholds for positioning accuracy or response latency that bring it within MTCR (Missile Technology Control Regime) or Wassenaar Arrangement controls?

If the product or technology sits within a controlled category, the startup needs a SCOMET export licence from DGFT for each transaction. The Inter-Ministerial Working Group (IMWG) processes recommendations for sensitive categories, comprising representatives from the Ministry of Defence, Ministry of External Affairs, Department of Atomic Energy, DRDO, and ISRO.

Transferring technology to a foreign investor through a licensing agreement, technical disclosure during due diligence, or a knowledge-sharing arrangement with an overseas research partner can constitute a “deemed export” under SCOMET rules. A startup that shares its core maritime autonomy stack with a foreign VC’s technical advisors before obtaining SCOMET clearance, where required, may be in breach even without any physical export.

India is a member of the Wassenaar Arrangement and the MTCR, which gives its export control framework international legal weight. Violations can result in licence suspension, penalties under the Foreign Trade (Development and Regulation) Act 1992, and reputational consequences that affect future government contracts.

What funding instruments are available for a deep tech maritime startup in India?

The funding landscape for maritime deep tech has materially changed in the 24 months to August 2026. Several mechanisms now exist that did not a few years ago, and the right funding path depends on the startup’s stage, technology type, and whether it has defence or purely commercial applications.

Startup India Fund of Funds 2.0: A gazette notification from April 2026 launched Fund of Funds 2.0 with a corpus of ₹10,000 crore to mobilise venture capital, with an expanded and explicit focus on deep tech startups. Fund management entities receiving commitments from this Fund of Funds may in turn invest in Category I AIFs under Securities and Exchange Board of India (SEBI) AIF Regulations 2012. A maritime deep tech startup raising from an AIF that has received Fund of Funds 2.0 capital benefits from a fund that has already passed government due diligence on its mandate.

Sagarmala Finance Corporation Limited (SMFCL): Formerly the Sagarmala Development Corporation, SMFCL was registered as a Non-Banking Financial Company (NBFC) with the Reserve Bank of India (RBI) on 19/06/2025. It now offers tailored financial products including short, medium and long-term funding to shipping companies, port authorities, MSMEs, and startups in the maritime sector. SMFCL and the Maritime Development Fund together target mobilising approximately ₹1.5 lakh crore for maritime financing.

India Maritime Development Fund: A dedicated ₹20,000 crore fund registered as an AIF under SEBI regulations, with a mandate to finance large-scale infrastructure projects in ports, shipping lanes and logistics systems. A deep tech startup supplying technology to these projects, rather than building infrastructure itself, should position for pilot contracts with infrastructure beneficiaries rather than direct fund capital.

IFSCA and GIFT City AIF route for foreign capital: International Finance Services Centres Authority (IFSCA) regulated funds in GIFT-IFSC benefit from a 10-year tax holiday under Section 80LA of the Income Tax Act for 10 out of 15 years on business income, full exemption from GST on management fees, zero STT and CTT on IFSC trades, and pass-through tax treatment for Category I and II AIFs without double taxation. For a maritime deep tech startup with a Singapore or UAE-based lead investor, structuring the investment through a GIFT-IFSC fund management entity can reduce the investor’s tax drag on returns, making the company more fundable at a given valuation. IFSCA also has a dedicated framework for ship leasing and financing that is directly relevant to startups building vessel fleets as part of their technology demonstration or revenue model.

Category I AIF (Venture Capital Fund sub-category): SEBI’s AIF Regulations 2012 govern fund structures for startup investment. A Category I AIF investing in a DPIIT-recognised deep tech startup receives pass-through tax treatment under Section 115UB of the Income Tax Act 1961, meaning the AIF itself does not pay tax on investment income; tax is assessed at the investor level. For a maritime deep tech startup, being in an AIF portfolio that has Category I status gives the investor a tax-efficient structure that compares well to direct offshore investment.

DSIR Scientific and Industrial Research recognition: The Department of Scientific and Industrial Research (DSIR) removed the three-year existence condition for deep tech startups seeking recognition under the Industrial Research and Development Promotion Programme. DSIR-recognised companies can claim a weighted deduction on R&D expenditure under Section 35(2AB) of the Income Tax Act 1961 for expenditure incurred at approved in-house R&D facilities. This deduction is available independently of DPIIT recognition and does not require IMB certification. For a capital-intensive maritime deep tech company spending ₹5 crore per year on sensor calibration, hull testing, and simulation software, the deduction directly reduces taxable income in profitable years and is worth pursuing in parallel with the DPIIT track, not sequentially.

iDEX and DAP 2020 for maritime startups with dual-use technology: A material share of maritime deep tech products sit inside India’s defence acquisition framework, even when the founder’s primary intent is commercial. Autonomous surface vessels, subsea acoustic sensors, encrypted maritime communication systems, and AI-based vessel tracking with EEZ monitoring capability are all technologies the Ministry of Defence procures under the Innovations for Defence Excellence (iDEX) programme and the Defence Acquisition Procedure 2020 (DAP 2020). iDEX funds startup-stage innovation through grants of up to ₹1.5 crore per problem statement under the DISC (Defence India Startup Challenge) scheme, with no equity dilution. The DAP 2020 “Buy Indian-IDDM” (Indigenously Designed, Developed and Manufactured) category gives certified Indian startups a procurement preference for defence acquisition above defined value thresholds. For a maritime deep tech startup, iDEX participation is simultaneously a non-dilutive revenue source, a validation signal for subsequent commercial investors, and a pathway to a defence department relationship that supports the government procurement revenue model. The compliance obligations, primarily security clearances for the founding team, DPIIT recognition, and end-use certification for exported products, need to be in place before a DAP procurement can close.

Common mistakes that cost maritime founders time and money

Treating the company as a standard tech startup for compliance purposes. A maritime deep tech company that builds an autonomous surface vessel is simultaneously a technology startup, a potential vessel operator, and a dual-use technology exporter. Running standard startup compliance without mapping the maritime regulatory layer means gaps appear at the worst time: during investor due diligence or before a port authority pilot.

Not filing patents before conference presentations. The Indian Patent Office operates on a first-to-file system. A startup that presents a novel subsea sensor array at an academic conference or a maritime industry event before filing a provisional patent application has created prior art against itself. The presentation date becomes the date of disclosure, and any patent filed after that date must show it was not obvious given the disclosure, which is a higher bar. File the provisional before you present, always.

Ignoring SCOMET at the seed stage. Founders assume SCOMET is a problem for large defence contractors. The classification analysis needs to happen at product design stage, not at the Series A. If the product contains controlled technology, the go-to-market must be designed around licenced export pathways. Discovering this at due diligence delays rounds by 3 to 6 months.

Incorrect FDI instrument selection. A startup that issues optionally convertible notes to a foreign angel investor without confirming the instrument qualifies as equity under the NDI Rules has potentially created an ECB. ECBs in early-stage companies attract minimum maturity and end-use restrictions that make them impractical. The fix is to restructure to CCPS or CCDs, which requires a fresh board resolution, shareholder approval, and updated valuation, all with a funding deadline looming.

Missing FEMA filing deadlines. Form FC-GPR filed after 30 days of allotment is a compoundable offence under FEMA. The Reserve Bank of India’s compounding process adds cost and time, and for a startup about to raise a follow-on round, outstanding FEMA contraventions are a red flag that investors will ask about. The filing must happen before the cap table is considered clean.

Entering an iDEX or defence contract without security clearances in place. A maritime deep tech startup that responds to a DISC challenge or a DAP 2020 procurement without first confirming that the founding team holds the required security clearances from the Ministry of Defence, and that the company’s foreign shareholding does not breach the sectoral caps for defence technology, will find the procurement stalled at the final contracting stage. Security clearance applications can take 6 to 12 months. Running the SCOMET classification, the FDI cap check, and the clearance application in parallel with the iDEX application, not after winning it, is the right sequence.

Getting GST place-of-supply wrong on maritime services. A startup that charges 18% GST on a software subscription supplied to a foreign vessel operator and remitted in USD has incorrectly treated an export of service as a domestic supply. Conversely, a startup that zero-rates a hardware supply to a foreign company but delivers the goods to an Indian port for use on a domestic voyage may have incorrectly claimed zero-rating on what is effectively a domestic supply. Both errors attract demand notices, interest, and penalties under the GST Act. The place-of-supply analysis under Section 12 and Section 13 of the IGST Act 2017 must be documented at the contract stage, not at the GST filing stage.

Treelife practitioner note

In the maritime technology engagements we have run at Treelife, the most consistent pattern is that founders underestimate how early the sector-specific compliance layer needs to be addressed. A standard startup compliance checklist covers company incorporation, DPIIT recognition, GST registration, and basic FEMA filings. That checklist is necessary but not sufficient for a maritime deep tech company.

The specific problem we see repeatedly is the SCOMET blind spot. A founder building acoustic positioning systems or underwater communication protocols does not think of their product as dual-use because they are serving commercial oil and gas or aquaculture customers. But the technology performance characteristics, specifically acoustic frequency ranges, positioning accuracy, and communication encryption standards, often map directly to SCOMET-controlled parameters under the marine and avionics categories. When a foreign strategic investor (typically a Japanese or Korean shipping conglomerate) appears at the Series A with an interest in acquiring a licence or entering a technical partnership, the SCOMET question surfaces for the first time. At that point, the company has to run a classification analysis, apply for export authorisation if required, and potentially redesign the commercial agreement structure. This adds 4 to 6 months to what founders expected to be a straightforward close.

The second pattern we see is IP fragmentation: founding team members who contributed technology while at a university, a DRDO lab, or a previous employer, where the IP assignment to the startup was never formally completed. This is particularly common in maritime robotics, where founders often emerged from IIT Madras, NIOT, or NIO research environments. The remediation involves consent from the prior institution, assignment documentation, and sometimes a licensing arrangement for institutional IP that cannot be assigned. None of this is impossible, but it takes time and requires specialist legal advice, and it is far cheaper to resolve before incorporation than at Series B due diligence.

Frequently asked questions

Q: Does a maritime deep tech startup automatically qualify for deep tech recognition under the 2026 DPIIT framework?
A: No. Deep tech recognition is not automatic. The DPIIT Notification G.S.R. 108(E) dated 04/02/2026 requires applicants to submit additional documentation demonstrating significant R&D expenditure, meaningful IP ownership, and a clear commercialisation plan. The DPIIT online portal administers the application, and the startup must satisfy both general Startup India eligibility (private limited company or LLP, turnover below ₹300 crore) and the deep tech-specific criteria.

Q: How long does DPIIT recognition take for a deep tech startup?
A: Standard DPIIT recognition is typically processed within 3 to 4 weeks of a complete application. IMB certification for Section 80-IAC benefits takes an additional 3 to 6 months, depending on the technology complexity and the quality of the application. A well-documented R&D record and provisional patent filings materially improve IMB approval timelines.

Q: Can a maritime deep tech startup raise ECB (External Commercial Borrowing)?
A: Yes, but ECBs are subject to end-use restrictions, minimum average maturity periods, and all-in cost ceilings under the RBI’s ECB Framework (Master Direction RBI/FED/2018-19/67). R&D expenditure qualifies as a permitted end-use, but real estate, capital markets investments, and equity purchases do not. Most early-stage maritime tech companies find CCPS or CCD issuance to foreign investors to be a cleaner structure than ECB.

Q: What is the GIFT IFSC advantage for a maritime startup raising foreign capital?
A: A fund management entity registered with IFSCA in GIFT-IFSC benefits from a 10-year income tax holiday under Section 80LA, no capital gains tax on IFSC-listed instruments, and full GST exemption on management fees. A foreign investor routing capital through a GIFT-IFSC fund into a maritime deep tech startup pays lower effective tax on returns compared to a domestic AIF structure. IFSCA also has a dedicated ship leasing framework that can be relevant for startups that demonstrate technology on owned or leased vessels.

Q: Are autonomous vessels (USVs, AUVs) registered under the Merchant Shipping Act 2025?
A: The Merchant Shipping Act 2025 defines vessels broadly to include all water craft. The application of registration requirements to unmanned autonomous vessels is still being worked through the DGMA’s subordinate rule-making process. As of August 2026, the DGMA has issued a public consultation on rules under the Act. Startups building USVs or AUVs should monitor this process and plan for registration requirements that may apply once specific rules are notified.

Q: What is the Section 35(2AB) R&D deduction and who qualifies?
A: Section 35(2AB) of the Income Tax Act 1961 allows a company to claim a weighted deduction of 150% on expenditure on scientific research incurred at an approved in-house R&D facility. The facility must be approved by the Department of Scientific and Industrial Research (DSIR). This deduction directly reduces taxable income and is valuable for maritime deep tech companies with high hardware and testing costs.

Q: How does SCOMET licensing work for a maritime startup exporting technology?
A: The startup first classifies its product against the SCOMET list categories. If the product falls within a controlled category, it applies to DGFT for a SCOMET export licence for each transaction. The IMWG processes recommendations for strategic categories. Licences are transaction-specific but can be applied for on a programme basis for repeat exports to the same end-user. Processing times vary from 4 weeks to 3 months depending on the category and end-user country.

Q: What is the S2I2 programme and how does a startup access it?
A: The Sagarmala Startup and Innovation Initiative (S2I2), launched 19/03/2025 under the Ministry of Ports, Shipping and Waterways, connects maritime technology startups to port authority problem statements. The Maritime India Foundation implements the programme through Maritime Innovation Hubs at IIT Madras, IIT Bombay, IIT Kharagpur, and Indian Maritime University. A startup that matches a port authority’s technology requirement can access a structured pilot pathway outside the standard L1 tender process.

Q: Does FEMA apply to a startup receiving foreign grant funding (not equity)?
A: Foreign grants received by a private limited company are governed by the Foreign Contribution (Regulation) Act 2010 (FCRA) if received from a foreign source for social, educational, religious, economic, or cultural purposes. Most maritime technology grants from foreign government agencies or multilateral bodies fall within FCRA scope and require FCRA registration. This is separate from FEMA and is administered by the Ministry of Home Affairs. A startup that receives a foreign government grant into its operating account without FCRA registration is in breach even if the purpose is commercial R&D.

Q: Can a maritime deep tech startup list on the NSE Emerge or BSE SME platform?
A: Yes. Both platforms allow loss-making companies in the tech and deep tech category to list under the SME IPO framework if they meet minimum net worth and post-issue paid-up capital requirements. SEBI also issued the SWAGAT-FI framework in 2026 for trusted foreign investors (FPIs and FVCIs) which simplifies access for foreign institutional investors to Indian listed SME securities. For a maritime deep tech company, a secondary listing on NSE Emerge can provide liquidity for ESOP holders and early investors while the company continues R&D.

Q: Is there a specific tax benefit for R&D expenditure incurred before DPIIT recognition?
A: R&D expenditure incurred before DPIIT recognition can still qualify for deduction under Section 35(1) or Section 35(2AB) of the Income Tax Act 1961, provided DSIR approval is in place and the expenditure is on scientific research related to the business. DPIIT recognition is a separate benefit from DSIR recognition. A startup should pursue both tracks in parallel, not sequentially.

Q: How does the Merchant Shipping Act 2025 change liability exposure for a maritime technology company?
A: The 2025 Act modernises safety and environmental liability provisions in line with International Maritime Organization (IMO) conventions. A technology company that supplies autonomous navigation or propulsion systems to a vessel operator has potential product liability exposure if a system failure contributes to a maritime incident. The Act strengthens pollution liability and hot pursuit provisions. A maritime deep tech startup should ensure its commercial agreements include appropriate liability caps, indemnities, and insurance requirements, and should carry product liability insurance covering maritime incidents.

Q: What GST rate applies when a maritime deep tech startup supplies services to a foreign vessel in Indian waters?
A: The place of supply for services related to vessels physically located in Indian territorial waters is India, regardless of where the foreign vessel operator is incorporated. The supply is therefore subject to Indian GST at 18% (SAC 9987 for inspection, maintenance, and related technical services) unless the startup can establish that the service qualifies as an export under Section 2(6) of the IGST Act 2017, which requires the recipient to be outside India, the place of supply to be outside India, and payment in convertible foreign exchange. For at-sea technical services rendered while the vessel is in Indian waters, the place-of-supply override under Section 13 of the IGST Act typically brings the supply within the Indian tax net. The startup should document the place-of-supply determination at the contract stage and confirm with a GST advisor before issuing the invoice.

Q: How does iDEX work and what does a maritime startup need to qualify?
A: Innovations for Defence Excellence (iDEX) is a Ministry of Defence programme that funds startup-stage innovation through grants of up to ₹1.5 crore per selected problem statement under the Defence India Startup Challenge (DISC) scheme. The startup submits a proposal against a specific technology problem statement published by the MoD, iDEX, or a defence public sector unit. Selection involves a technical evaluation followed by a milestone-based grant disbursement, with no equity requirement. To qualify, the startup must be incorporated in India, hold DPIIT recognition, and have no foreign ownership above 49% in the defence technology category (or up to 74% under automatic route with MoD approval). Founding team security clearances are required before final contracting. iDEX grants are non-taxable receipts for the company but must be accounted for under the fund deployment restrictions of the DPIIT notification.

Q: What is the Section 80-IAC tax holiday and when should a maritime startup apply for it?
A: Section 80-IAC of the Income Tax Act 1961 (renumbered Section 140 under the Income Tax Act 2025 for FY 2026-27 filings) provides a 100% deduction on profits and gains for any 3 consecutive years out of the first 10 years (or 20 years for deep tech startups) from the year of incorporation, provided the startup is incorporated as a private limited company or LLP, holds DPIIT recognition, and obtains IMB certification. Two thresholds apply independently: DPIIT recognition is lost if turnover exceeds ₹300 crore; the 80-IAC deduction is lost in any year where turnover exceeds ₹100 crore, regardless of DPIIT status. A maritime startup with early defence contract revenue should model both before deciding which years to claim. The application for IMB certification should be filed once the company has at least one full year of financials and a clear technology narrative. Filing too early, before the technology is sufficiently documented, leads to rejection and restarts the clock.
