UK-India Trade Agreement: A Practical Guide for UK and Indian Businesses

The UK-India Comprehensive Economic and Trade Agreement (CETA) entered into force on 15 July 2026. The tariff landscape between the United Kingdom and India changed in ways that have not been available to either country for decades. The opportunity is real and the financial case is material. So is the compliance obligation.

This article is in two parts. The first sets out what the agreement means in financial and operational terms, written for Finance Directors and Logistics Directors who need the strategic picture without the procedural detail. The second sets out what the agreement requires in practice, drawn directly from the legal text, written for Customs Directors and the teams responsible for implementation. Both parts address UK businesses and Indian businesses, because the obligations and the opportunities differ depending on which side of the trade you are on and we support clients in both countries.

Part One: What This Agreement Means for Your Business

The Financial Opportunity

The UK government projects long-run annual increases of £4.8 billion to UK GDP and £25.5 billion to bilateral trade. Those projections are modelled over the full ten-year staging period. The more immediate question is what changed on 15 July and what it is worth.

For UK businesses exporting to India, 64% of Indian tariff lines become duty-free from entry into force, rising to 85% over ten years. Estimated duty savings for UK exporters to India amount to £400 million per annum at entry into force, rising to £900 million after ten years. Scotch whisky and gin face a tariff reduction from 150% to 75% on day one, reducing further to 40% by year ten. Automobiles move from up to 110% to 10% under a tariff rate quota. Medical devices, precision instruments, and a wide range of manufactured goods gain duty-free access immediately.

For Indian businesses exporting to the UK, 99% of UK tariff lines are liberalised at entry into force. Estimated duty savings for Indian exporters amount to £220 million per annum from day one. The principal beneficiaries on the Indian side are textiles, leather, marine products, gems and jewellery, engineering goods, and chemicals.

For Finance Directors modelling the commercial case, the starting point is not the headline tariff reduction. It is the duty cost currently paid on India-sourced imports, or absorbed into export pricing for the Indian market, commodity line by commodity line, against the preferential rate for each of those lines. That calculation determines the actual financial benefit available to any given business. The aggregate government figures are directionally correct. The business-level figure requires a commodity-by-commodity analysis.

The Compliance Obligation

The tariff reductions under the agreement are not automatic. They require three things.

First, the goods must qualify as originating under the Rules of Origin set out in Chapter 3 of the agreement. Goods that are simply traded between the UK and India, or that undergo only minor processing in either country, do not automatically qualify. There is a legal test, and it must be met. For many manufactured goods the test requires that a minimum proportion of the value of the finished product originates in the UK or India, or that the production process results in a change in tariff classification. The specifics vary by commodity code and must be verified against Annex 3A.

Second, UK exporters must register with HMRC before completing a valid origin declaration for an Indian customer. Without registration, no Indian importer can claim preferential treatment on UK goods. Indian exporters must either obtain a certificate of origin from a designated Indian issuing authority or complete an origin declaration themselves. The process differs by direction of trade and is set out in Part Two below.

Third, the documentation must be created, authenticated where required, and retained. The agreement requires importers to keep records for four years from the date of importation, and exporters and producers for five years. Customs authorities may verify claims retrospectively for up to two years in the normal course, and up to five years where fraud is suspected (Articles 3.24 and 3.25, UK-India CETA Chapter 3). A preference claim that cannot be substantiated by documentation is not a preference claim: it is a potential liability.

The Risk of Inaction

The agreement permits retrospective claims for up to one year from the date of importation, provided the goods were originating at the time (Article 3.20, Chapter 3). Businesses that are not ready on 15 July can therefore still recover duties paid on qualifying imports made after that date, within the one-year window. However, the retrospective route requires that the goods genuinely qualified. It is a recovery mechanism for compliant goods whose preference was not claimed at the time: it is not a route to remediate goods that did not meet the origin criteria.

For Finance Directors: the financial cost of inaction is the full MFN rate paid on goods that qualified for preferential treatment, for as long as the preference is not claimed. On high-volume import or export flows that is a quantifiable sum. Against that, the investment required to establish compliance is a one-time structured exercise: an origin analysis for the relevant commodity codes, HMRC registration where applicable, and a documentation process. The return on that investment is quickly recoverable from qualifying shipments.

Three Actions for Preparation

UK exporters to India should register with HMRC . Without registration, Indian customers cannot claim preferential treatment from day one, regardless of whether the goods qualify. Registration is free and requires one application.

UK importers from India should contact their Indian suppliers to obtain CETA-compliant proof of origin. For traders currently using DCTS documentation, the Rules of Origin and origin declaration used under the DCTS are not valid under the CETA: this distinction is addressed in Part Two below.

Both UK and Indian businesses should carry out an origin analysis for the goods on which they intend to claim preference before making any claim. A claim made without an underlying origin analysis is a claim that cannot be substantiated: it creates audit exposure without delivering a reliable financial benefit.

Part Two: The Operational and Legal Detail

The sections below set out the agreement’s requirements drawn directly from the legal text. They are written for Customs Directors, supply chain managers, and the advisers supporting implementation.

The Tariff Schedules: Staging Categories and the MFN Floor

The tariff commitments are set out in Chapter 2 and Annex 2A, with India’s commitments in Appendix 2A-a and the UK’s in Appendix 2A-b.

India’s staging categories cover a range of reduction paths: immediate elimination, elimination over five years, over seven years, over ten years, reduction to a fixed end-point rate over ten years, and exclusions where no concession is made. The whisky and gin staging category is defined as a reduction to 75% of the base rate on entry into force, then reduction in nine equal annual instalments beginning 1 January of year two, reaching 40% of the base rate by year ten. The base rate for these goods is 150%, comprising Basic Customs Duty, Agriculture Infrastructure and Development Cess, and Social Welfare Surcharge in aggregate. The day-one preferential rate is therefore 75% applied to the combined base rate.

One provision warrants specific attention. Under Article 2.6(3) of Chapter 2, where India’s applied MFN rate on a given tariff line is lower than the CETA preferential rate at any point during the staging period, the importer may apply the lower MFN rate. The preferential rate only delivers value where it undercuts the prevailing MFN rate. For goods on which India has already reduced its MFN tariff substantially, the additional benefit of CETA preference may be modest. Importers should verify the applicable MFN rate for each commodity code before assuming the CETA rate.

Certain categories are excluded from India’s tariff commitments entirely, including sugar, milled rice, pork, chicken, eggs, dairy, apples, edible oils, and gold (Appendix 2A-a, staging category Exclusion). Exclusion means no preferential rate is available: MFN applies in full.

Rules of Origin: The Three Criteria

Preferential tariff treatment is only available to goods that qualify as originating under Chapter 3. Under Article 3.2, a good qualifies if it meets one of three criteria: it is wholly obtained or produced entirely in the territory of one or both parties (Article 3.3); it is produced entirely from originating materials; or it satisfies all applicable requirements of Annex 3A.

Wholly obtained goods include those extracted, grown, harvested, born, or raised entirely within the UK or India, fish caught within territorial waters by registered vessels, and waste or scrap derived from production or consumption within either party.

The product-specific rules apply the usual three principal methods: a change in tariff classification, requiring that non-originating materials used in production are classified under a different HS heading or chapter from the finished good; a qualifying value content threshold, calculated either by build-down or build-up; or a specific manufacturing process. The applicable method and threshold vary by commodity code and must be verified against Annex 3A for each product.

Tolerance

Where a good does not satisfy the applicable change in tariff classification requirement, it may nonetheless qualify if the value or net weight of non-originating materials falls within the tolerance thresholds of Article 3.9. For goods in HS Chapters 1 to 3, 5, 6, 10, and 14, the tolerance is 7.5% by value or net weight. For goods in Chapters 4, 7 to 9, 11 to 13, and 15 to 24, the tolerance is 12.5%. For goods in Chapters 25 to 98, the tolerance is 12.5% by value.

Cumulation

Under Article 3.8, originating materials from either the UK or India incorporated in production in the other party count as originating. A UK manufacturer incorporating Indian-origin components may count those components as originating materials when assessing whether the finished good meets the applicable product-specific rule. The same applies in reverse.

Non-Qualifying Operations

Article 3.7 lists operations that do not confer origin regardless of where they are performed. These include operations to preserve goods during transport and storage; changes of packaging; washing, cleaning, and simple painting; husking, bleaching, and polishing of cereals and rice; simple placing in bottles, cans, or boxes; affixing labels; simple mixing; simple assembly of parts; and slaughter of animals. The article defines “simple” as an activity requiring neither special skills nor machines especially produced or installed for the purpose.

A supply chain model premised on importing goods and performing only minor finishing or repacking operations before export will not confer origin. The transformation must be substantive and must satisfy the applicable product-specific rule in Annex 3A.

Proof of Origin: The Asymmetry Between UK and Indian Importers

The proof of origin framework in Article 3.15 operates differently depending on the direction of trade, and the distinction is material.

UK importers sourcing goods from India may rely on any one of three forms of proof: an origin declaration completed by the Indian exporter or producer; a certificate of origin issued by a designated Indian issuing authority under Article 3.17; or the importer’s own knowledge that the good is originating, supported by documentation demonstrating that the good qualifies. The importer’s knowledge route gives UK importers a degree of autonomous control over their preference claim although it is difficult to manage.

Indian importers sourcing goods from the UK may only rely on an origin declaration completed by the UK exporter or producer. There is no certificate of origin route from the UK side, and no importer’s knowledge route into India. An Indian importer whose UK supplier has not registered with HMRC, or is unwilling or unable to complete a valid declaration, has no alternative basis on which to claim preferential treatment.

The HMRC Registration Requirement

UK exporters and producers wishing to complete origin declarations for Indian importers must register with HMRC before completing any declaration. Registration requires the exporter’s EORI number. Once registered, HMRC assigns a unique reference and a registered email address, both of which are shared electronically with India’s Central Board of Indirect Taxes and Customs and held in an Indian database of registered UK exporters.

A UK exporter who ships to India without having registered will find that their Indian customer cannot claim preferential tariff treatment and will pay the full MFN rate. Registration is free, completed once, and is a prerequisite for everything else.

The Authentication Process

The authentication process in Annex 3D is one of the most operationally distinctive features of this agreement. When a UK exporter has completed an origin declaration in the Annex 3B format, they must send it by email simultaneously to the CBIC nodal email address and to the Indian importer, in a file format and with a subject line structure agreed between the parties. India’s CBIC reviews the declaration against their database of registered UK exporters. If the information matches, CBIC notifies the UK exporter and copies the Indian importer, confirming that authenticity has been established. If it does not match, CBIC notifies the UK exporter that authenticity has not been established, and no preferential claim may be made.

This is not a standard self-certification arrangement. Origin declarations must be routed through the authentication process before they have legal effect. UK exporters should establish this email process and confirm the correct CBIC address before their first shipment. At the time of writing, the operational CBIC nodal email address and agreed file format specifications had not been published.

The Origin Declaration Template

The origin declaration must follow the Annex 3B template and must include: the signatory’s name and contact details; exporter details; producer details if different from the exporter; importer details if known; the signatory’s EORI number for UK signatories or Importer Exporter Code for Indian signatories; the HS tariff classification at 6-digit level; a description of the goods; the invoice number and date; the origin criterion used; and, if applicable, a declaration of the specific product-specific rule applied. The declaration must be in English and is valid for 12 months from the date of completion.

Multiple Shipments

A single origin declaration may cover multiple shipments of identical goods imported into the UK within any period not exceeding 12 months (Article 3.15(3), Chapter 3). This multiple-shipment provision applies to UK importers only. Indian importers must obtain a declaration per shipment. For high-volume UK importers sourcing regularly from a single Indian supplier, the multiple-shipment declaration reduces administrative burden significantly. For Indian importers buying regularly from a UK supplier, the per-shipment requirement means the UK exporter must complete and authenticate a separate declaration for each consignment.

Certificates of Origin for Indian Exports

Indian exporters to the UK have the option of obtaining a certificate of origin from an Indian issuing authority designated under Article 3.17, rather than completing an origin declaration. The certificate must follow the Annex 3C template. Indian exporters should check with the DGFT and CBIC for operational guidance.

Late Claims

Under Article 3.20, a late claim for preferential treatment may be made within one year of the date of importation, provided the good was originating at the time it was imported. A proof of origin completed retrospectively must state that it has been completed retrospectively and provide a brief explanation.

Businesses with Entities in Both Countries

A business that has both a UK entity and an Indian entity is in a structurally advantaged position: it controls both ends of the transaction, including the origin analysis, the HMRC registration, the authentication submission, and the import declaration. The supply chain structuring opportunity described below is most directly accessible to this group. The compliance obligation, however, runs fully in both directions: the UK entity must maintain five-year records as exporter and producer; the Indian entity must retain four-year records as importer and manage the authentication process from the Indian side.

The DCTS Transition for UK Importers

India has until now been a beneficiary country under the UK’s Developing Countries Trading Scheme, specifically under the Standard Preferences tier, governed by SI 2023/561. Under the DCTS, eligible Indian goods entered the UK at reduced or zero duty rates, supported by a DCTS-specific self-certified origin declaration.

From 1 January 2026, goods graduation under regulation 18(1) and Schedule 3 of SI 2023/561 suspended DCTS Standard Preferences on specific categories from India: textiles, chemicals, articles of iron and steel, and precious metals. This graduation runs until 31 December 2028 and operates independently of the CETA.

On 15 July 2026, the CETA entered into force. At the time of drafting, no statutory instrument formally removing India from the DCTS country list upon CETA entry into force had been identified in the public record. The mechanism by which the DCTS is superseded by the CETA is therefore not confirmed in any published subordinate legislation reviewed. Nevertheless, given that 99% of UK tariff lines are liberalised at entry into force, the CETA rate will, in most cases, be at least as favourable as the DCTS Standard Preference rate, and often more so.

For goods subject to DCTS graduation from January 2026, that is textiles, chemicals, steel articles, and precious metals, that fall within the CETA schedule and meet CETA origin criteria: the DCTS rate is already suspended, and the CETA is the only available preferential route for those goods.

The DCTS Rules of Origin and origin declaration, which use DCTS-specific criteria and wording, are not valid under the CETA.

Non-Alteration, Transit, and Third-Country Routing

The agreement does not impose a direct shipment requirement. Originating goods may transit through or be stored in third-country territories without losing preferential status, subject to the following conditions: the good remains under customs control and is not released to free circulation or trade in any third country; and the good does not undergo any further production beyond unloading, reloading, splitting of loads, storage, labelling, marking, or preservation operations. Spirits may be bottled in a third country under defined conditions without loss of origin (Article 3.14(2), Chapter 3).

Where goods transit through a third country, the importer must be able to demonstrate on request that these conditions were met, through freight documentation evidencing an unbroken customs control chain: transit documents, warehouse receipts, or a non-manipulation certificate from the customs authority of the transit country as applicable (Article 3.14(3), Chapter 3).

Supply chains routed through distribution hubs in the Gulf, South Asia, or Southeast Asia are not automatically disqualified. The documentary obligation increases in complexity relative to direct shipment, and Logistics Directors should ensure freight providers can produce the documentation required to satisfy a verification request.

Supply Chain Structuring: The Duty Suspension Opportunity

The agreement contains no drawback prohibition and no restriction on the concurrent use of duty suspension regimes such as Inward Processing Relief, Outward Processing Relief, or customs warehousing.

Under IPR, businesses import non-originating materials duty-free on the basis that those materials will be processed and the finished goods exported. If the finished goods produced from IPR materials satisfy the applicable product-specific rules of origin in Annex 3A, those goods qualify as originating and may be exported to India with a valid CETA preference claim. The qualifying value content calculation under Article 3.5 uses the CIF import value of non-originating materials and makes no distinction between materials on which import duty has been paid and materials that entered under a duty suspension regime. The absence of a drawback prohibition means that duty relief on inputs through IPR and preferential treatment on exports to India are not in conflict (Article 3.5, Chapter 3).

For UK manufacturers importing components or raw materials from third countries for processing in the UK before export to India, duty is suspended on inputs under IPR and preference reduces the duty on outputs under the CETA. The two regimes operate without mutual restriction.

Article 2.14 of Chapter 2 contains a specific provision for goods re-entered after repair or alteration. A UK good exported temporarily to India for repair or alteration and returned to the UK attracts customs duty only on the value added by the repair or alteration, not on the full re-imported value. This provision applies regardless of origin and is embedded in the CETA itself.

There is no restriction in the CETA on goods being placed into a customs warehouse before a preference claim is made. The non-alteration provisions of Article 3.14 permit storage under customs control, and the preference claim is made at the point of release to free circulation, not at the point of importation into warehouse.

Two caveats must be stated directly. IPR use does not itself confer origin. The product-specific rules in Annex 3A govern whether the transformation is sufficient. Simple operations under Article 3.7 will not satisfy the origin test regardless of the customs regime under which the inputs arrived. The planning opportunity exists only where the processing is genuinely substantive and the applicable product-specific rule is met. The interaction of IPR with the product-specific rules requires a proper origin analysis for each product: it should not be approached as an assumption.

Customs and Trade Facilitation: Binding Commitments

Chapter 5 sets out customs and trade facilitation commitments that are binding legal obligations.

Release of the goods: under Article 5.5, each party undertakes to release goods as rapidly as possible and to endeavour to release goods within 48 hours of arrival, provided all required documentation has been received, the goods are not subject to physical inspection, and all regulatory checks have been completed.

Simplified Procedures: under Article 5.4, each party must adopt or maintain simplified customs procedures for eligible traders, including deferred payment of customs duties until after release and the ability to make consolidated periodic duty payments covering multiple imports.

Binding Information / Advance Rulings: under Article 5.8, each party must issue advance rulings on tariff classification, whether a good is originating under Chapter 3, and the appropriate method for determining customs value, within three months of receiving a complete application. Rulings are binding on the customs authority that issues them. For businesses planning significant volumes under preferential treatment, an advance ruling on origin provides the most defensible compliance position before shipments begin.

Post-clearance audit: under Article 5.15, post-clearance audit is each party’s primary compliance mechanism, conducted on a risk basis. Goods are released and audited after the fact. This accelerates clearance but places greater weight on the quality of record-keeping.

Customs representative: under Article 5.16, neither party may require the mandatory use of customs agents.

Authorised Economic Operator: under Article 5.9, each party must establish or maintain an Authorised Economic Operator programme in accordance with the WCO SAFE Framework. The CETA does not provide for mutual recognition of UK and Indian AEO programmes at entry into force. Businesses holding UK AEO status should not assume this confers automatic facilitation benefits at Indian customs: it does not.

Sanitary, Phytosanitary Measures, and Quality Control Orders

Chapter 6 establishes a framework for sanitary and phytosanitary measures. The chapter commits both parties to applying import conditions consistently across the entire territory of the exporting party (Article 6.7(1)), and to not refusing importation of a good solely because a review of SPS measures is underway, provided importation was permitted when the review was initiated (Article 6.7(12)). Both parties reaffirm their rights and obligations under the WTO SPS Agreement (Article 6.4).

What Chapter 6 does not do is prohibit or limit India’s use of Quality Control Orders. India’s QCOs are domestic technical regulations requiring that specified goods meet Bureau of Indian Standards certification before they can be imported. They operate under the Technical Barrier to Trade (TBT) framework, and the CETA’s TBT chapter similarly creates consultation mechanisms but does not prohibit QCOs.

The UK House of Commons Business and Trade Committee (HC 996, January 2026) and the House of Lords International Agreements Committee (HL 253, February 2026) identified QCOs as a material risk to the realisation of the agreement’s commercial benefits. QCOs have been expanding in scope, are sometimes imposed with limited prior notice, and can effectively exclude goods that technically qualify for preferential tariff treatment. The CETA provides a formal channel through which unjustified barriers can be challenged through SPS and TBT subcommittees and, ultimately, the dispute settlement mechanism of Chapter 29: it does not prevent QCOs from being imposed.

For UK exporters in food, agriculture, processed goods, medical devices, and electronics, the gap between the tariff reduction and the effective market access must be assessed product by product. A reduced tariff rate does not guarantee unobstructed entry into the Indian market. Exporters should verify current BIS certification requirements for their specific goods before assuming that preferential tariff access translates directly into commercial access.

Record-Keeping and Audit Exposure

Under Article 3.24, importers must retain all proof of origin documentation and supporting records for at least four years from the date of importation. Exporters and producers must retain origin declarations and all underlying evidence for five years from the date of completion of the declaration.

Customs authorities may initiate verification at any time after a claim is made. In the normal course, a written request for verification information must be made no later than two years after the date of the preference claim. In cases of suspected fraud, the verification window extends to five years (Articles 3.25(4) and 3.25(5), Chapter 3).

The verification process is bilateral and structured. If the importing party’s customs authority considers the importer’s information insufficient, it requests assistance from the competent authority of the exporting party, which has seven months in which to respond (Article 3.25(4) and (9), Chapter 3).

Under Article 3.26, where two successive verifications in respect of the same exporter or producer result in denial of preferential treatment, the importing party may temporarily suspend the preferential rate for future imports of the same goods from that exporter or producer. This provision concentrates compliance risk on those who claim preference without having conducted the underlying origin analysis. A pattern of incorrect claims is not merely a financial liability: it can result in suspension of the preferential rate itself.

A business that begins claiming preference from 15 July 2026 must maintain documentary evidence supporting those claims until at least July 2030 on the import side and July 2031 on the export side, with the five-year verification window extending further in fraud cases. Additional domestic requirements may extend this duration.

Advance rulings under Article 5.8 are the most defensible instrument available to businesses planning significant volumes under preference. A ruling confirming origin status, issued by HMRC or by the relevant Indian authority, is binding on the customs authority that issued it and provides the clearest available protection against a subsequent verification challenge.

Beyond the Legal Text: Three Implementation Risks

India’s administrative capacity

India has not previously brought a trade agreement of this size and complexity into force. The authentication mechanism in Annex 3D and the Indian issuing authority infrastructure for certificates of origin were being finalised at the point of entry into force.

UK exporters and Indian importers should not assume that the preference infrastructure will operate without friction from day one. Building contingency time into the first authentication submissions is prudent.

The UK Carbon Border Adjustment Mechanism

The UK is introducing its own CBAM from 1 January 2027, covering imports of iron, steel, aluminium, cement, fertilisers, and hydrogen. For businesses importing these products from India under CETA preferential tariff rates, the CBAM will add an embedded carbon cost dimension to the landed cost calculation from next year. The CETA reduces the tariff component; the CBAM adds a carbon cost overlay. These operate in parallel and must be modelled together by businesses in the affected sectors.

The EU-India trade agreement

The European Union concluded its own trade agreement with India in January 2026, with entry into force expected no earlier than early 2027. The UK’s first-mover advantage is real: it is also time-limited. UK exporters who plan to use the CETA window to establish market positions in India ahead of European competition should act on that plan now rather than when the EU agreement enters into force.

How to adapt: By Direction of Trade

UK exporters to India should register with HMRC immediately if not already registered. Once registered, an origin analysis should be commissioned for each product on which preference will be claimed, the CBIC authentication process and nodal email address should be confirmed, and commercial and logistics teams should be trained on the Annex 3B declaration requirements.

UK importers from India should monitor HMRC confirmation of the relationship between the DCTS and the CETA. It is important to note that the DCTS Rules of Origin and Origin Declaration, which use DCTS-specific criteria and wording, are not valid under the CETA. Whether graduated goods, that is textiles, chemicals, steel, and precious metals, now qualify for CETA preference should be checked on a commodity-by-commodity basis.

Indian exporters to the UK should identify which products benefit from preferential tariff rates and carry out an origin analysis against Annex 3A. Guidance should be obtained from designated Indian issuing authorities on the certificate of origin process, or, if completing origin declarations directly, the IEC code should be confirmed as current and declarations verified against the Annex 3B format.

Indian importers from the UK should verify that their UK suppliers are registered with HMRC. Without registration, no valid declaration can be authenticated and no preferential claim can be made. A process should be established for receiving and checking origin declarations before making preference claims, and record-keeping should be set up to retain proof of origin for four years from each import date.

Businesses with entities in both countries should treat this as an integrated planning exercise. The origin analysis, HMRC registration, authentication process, and import declaration strategy can be aligned across both entities. The supply chain structuring opportunity from concurrent IPR use and CETA preference is most accessible to businesses that control both sides of the transaction.

In all cases: the agreement permits retrospective claims within one year of importation. That window exists for compliant goods whose preference was not claimed at the time: it is not a substitute for having a compliance architecture in place before 15 July.
