India-UK CETA: What Buyers Must Verify and Suppliers Must Prove
Ninety-nine percent of India's tariff lines into the UK went to zero duty on July 15, 2026, when the India-UK Comprehensive Economic and Trade Agreement (CETA) came into force. That does not mean a UK buyer automatically pays less for an Indian-made part starting that day. The preferential rate applies per product, not per country of origin and it only applies when that product's origin is documented correctly. A supplier that actually qualifies can still cost the buyer the duty saving over one missing signature, the wrong issuing body or a value-addition calculation that doesn't actually clear the threshold. This guide covers what actually determines whether a specific product qualifies, how the certificate process works for Indian exporters (a different process than the one used in the other direction) and what a buyer should verify before counting on the saving, not after a shipment is already at customs.
What Changed on July 15, 2026
CETA removed duty on 99% of India's tariff lines into the UK, covering more than 15,000 individual HS code entries across over 20 sectors. Before the agreement, engineering goods and auto components carried tariffs as high as 18%, with rates across the broader engineering category ranging roughly 2% to 16% depending on the specific line. For a UK buyer, that tariff sat inside the total landed cost of every quote from an Indian supplier, whether or not it was ever broken out as its own number.
Metals move at different speeds. Scrap tariffs phase in by grade and finished steel sits inside its own separate structure: a UK global safeguard, unrelated to CETA, that cut duty-free quota volume 51% from July 1, 2026, with a 50% tariff on anything shipped above it. Steel also runs on a different origin test than the QVC framework in the rest of this guide, a melt-and-pour condition rather than a value-addition percentage; the downloadable worksheet's Quick Reference tab covers it separately, since applying the general thresholds below to a steel part gives the wrong answer.
None of this is small. India's engineering exports to the UK ran at roughly $4.7 billion in 2025/26 and the government-industry target is to push that past $7.5 billion by 2029-30, with CETA named as the mechanism. That is real headroom in a market currently supplied by a small number of already-visible Indian exporters. Headroom only converts into orders, though, for a supplier that can actually prove the origin claim a buyer is now motivated to ask for.
Why "Made in India" Is Not the Same as "CETA-Qualifying"
CETA does not grant blanket zero-duty status to anything shipped from an Indian factory. Every product qualifies or doesn't based on its own Product Specific Rule (PSR), set out by HS code in the agreement's tariff schedule. A rule can require a change in tariff classification, meaning the finished good has to be classified differently than the imported inputs that went into making it, a minimum share of qualifying value content or both.
This is the step most quotes and most buyer assumptions skip. A supplier saying "we're CETA-eligible" is a country-level claim. A specific bracket, casting or wiring harness actually qualifying is a per-HS-code claim and the two are not interchangeable. Under CETA, products qualify, not companies. A shop can be fully eligible on nine of ten parts it makes and fail the tenth, if that tenth part draws more of its value from an imported input than its specific rule allows.
How Value Addition Actually Gets Calculated
Where a PSR sets a minimum value-addition share, called Qualifying Value Content (QVC), the calculation runs one of two ways. The build-down method starts from the finished product's value and subtracts the value of non-originating materials. The build-up method starts from zero and adds up what the originating materials actually contributed. The threshold depends on both the method and the value base. Build-up stays at 35% regardless of whether ex-works or FOB is used. Build-down runs higher and splits by base: 40% on an ex-works value, 45% on an FOB value. Which method and base apply is set by the specific rule for that HS code, not chosen freely by the exporter.
One detail changes this math for a lot of suppliers: bilateral cumulation. A UK-origin input used in Indian production counts as originating material in the QVC calculation, not as a non-originating input dragging the percentage down and the same works in reverse for a UK producer using Indian-origin inputs. A supplier who doesn't know cumulation exists will undercount their own qualifying value and can walk away from a claim that actually clears the threshold.
Ex-works price covers materials, direct manufacturing cost and allocated overhead and profit. It excludes refundable taxes and anything that happens after the goods leave the factory, like freight or insurance. Getting this number right requires an actual cost breakdown of the part, not an estimate. In practice, that breakdown starts from the product's manufacturing BOM and purchase records, not a figure built specifically for the certificate. A supplier who has never built one before will need to, because "we think we're well over the threshold" is not documentation a certificate issuer or a customs auditor, will accept.
Getting the Certificate Right: Two Systems, Not One
This is where a lot of the confusion already circulating about CETA comes from. Both trade directions now have a self-declaration option, but they run on different mechanisms with different requirements and mixing them up is the single most common mistake in early commentary on this deal.
For UK-origin goods entering India, CETA introduced a trust-based self-declaration system. The UK exporter or producer completes their own origin declaration and it is authenticated under a CBIC framework rather than issued by a separate certifying body.
For Indian-origin goods entering the UK, exporters have two options, both filed through DGFT's Trade Connect ePlatform, live since July 15, 2026. One is a Certificate of Origin issued by an authorized body: a DGFT-designated agency, an Export Promotion Council or a designated Chamber of Commerce. The other is a self-declared electronic Certificate of Origin, generated by the exporter directly using a Digital Signature Certificate linked to their Importer Exporter Code (or Aadhaar authentication), with no agency in the process.
An Indian exporter reading a CETA explainer written from the UK side will still get the mechanics wrong if they assume the two directions run on an identical process. They don't. What's true on both sides is that a self-declaration path exists; what differs is who authenticates it and how it's generated. Either route on the Indian side, agency-issued or self-declared, has to be filed through Trade Connect for the claim to hold.
The Gap Nobody's Explaining: Authenticated Is Not the Same as Verified
Here is the detail that matters most and gets mentioned least. Authenticating a Certificate of Origin or an origin declaration, confirms it was properly completed and filed by who it claims to be from. It does not, by itself, confirm that the underlying goods actually meet the origin rule. Customs can still check separately whether a shipment's goods actually qualify, even after a certificate has been accepted and the preferential rate applied.
That means a buyer can take the zero-duty rate today, in good faith, on a certificate that looks entirely in order and still owe the duty back later if an audit finds the underlying value-addition calculation doesn't actually clear the threshold. The certificate proves the paperwork was filed correctly. It does not, on its own, prove the goods qualify. Those are two different facts, checked at two different points and most explainers of this agreement collapse them into one.
This is the exact problem a verification-led sourcing relationship exists to close. Not filing the certificate faster, but knowing before an order ships whether the underlying claim will actually hold up if it's ever checked.
What a Buyer Should Verify Before Relying on a CETA Quote
| Check | What to actually confirm |
|---|---|
| The HS code | Get the specific HS code from the supplier in writing, not just "this qualifies for CETA." |
| The PSR basis | Ask whether the rule for that code needs a tariff classification change, a value-addition threshold or both. |
| The calculation | Ask to see the value-addition calculation itself (build-down or build-up), not just a certificate number. |
| The issuing body | Confirm whether the Certificate of Origin was issued by a DGFT-authorized agency, EPC, or Chamber, or self-declared by the exporter under a DSC linked to their IEC. Either is valid; know which one you're holding. |
| The importer's-knowledge option | Know that a certificate or declaration isn't the only route. CETA also lets a UK importer claim the preference on their own knowledge of the supply chain, without either document, if they can support that knowledge themselves. Riskier to rely on alone, but worth knowing it exists. |
| The filing | Before a customs broker claims the preference, confirm the Certificate of Origin or origin declaration references the same HS code, commercial invoice, and shipment as the goods actually being imported. |
| The contract | Add a clause on who bears the cost if the origin claim is rejected on a later customs audit, and who responds to customs enquiries and supplies supporting documents if the claim is challenged. |
| The habit | Repeat this per product. "This supplier is CETA-eligible" is a claim, not a fact, until it's checked part by part. |

Comparing Two Supplier Quotes Under CETA
A UK buyer gets two quotes for the same bracket. Supplier A prices it landed duty-free under CETA. Supplier B quotes the standard tariff rate and doesn't mention CETA at all. The two numbers aren't actually comparable yet, because one of them is a commercial price and the other is a commercial price with a customs assumption built into it.
Separate the two before comparing landed cost. Get the EXW or FOB price on its own, then ask Supplier A for the HS code, the PSR basis it's claiming and who bears the cost if the origin claim is rejected on a later audit. If Supplier A can't answer those three questions, the quote isn't duty-free, it's a duty-free assumption with someone else's downside risk attached. Priced correctly, Supplier B's fully-tariffed, fully-certain quote can turn out to be the safer number, even when it looks higher today.
What a Supplier Needs on File Before Quoting on CETA Terms
| Check | What to actually have ready |
|---|---|
| The rule | Know the product's HS code and its specific PSR before quoting a preferential rate. |
| The calculation | Build the value-addition calculation, ex-works or FOB basis, with a real cost breakdown, not an estimate. |
| The inputs | List every non-originating material used and its value, backed by supplier invoices. |
| The records | Keep production records tied to the specific shipment, not just the finished part's spec sheet. |
| The certificate | File through DGFT's Trade Connect ePlatform, either through an authorized issuing body or self-declared with a DSC linked to your IEC. |
| The retention | Keep the full file for 5 years from the date the Certificate of Origin or origin declaration was issued, the confirmed retention period on the Indian side. |
The CETA Origin Qualification Worksheet
Both tables above are the short version. The full worksheet (free download, Augmino-CETA-Origin-Qualification-Worksheet.xlsx) is a 4-tab workbook: a Quick Reference tab with the QVC thresholds, certificate routes and retention rule at a glance, a Supplier Worksheet and a Buyer Worksheet, each running the same process as the tables above with a Yes/No/N/A answer column and an automatic Overall Verdict once every row is filled in. It is built to be filled in once per product, not once per relationship, since qualification is a per-HS-code fact, not a per-supplier one.
Qualification Isn't a One-Time Check
A product that qualified once doesn't stay qualified by default. The calculation was built on a specific bill of materials, a specific source for the non-originating inputs and a specific manufacturing process. Change any of those, a different steel supplier, a revised BOM, a subcontracted operation that wasn't there before and the origin calculation needs to be redone before the next shipment claims the preference, not assumed to still hold. Treat it the same way a drawing revision triggers a re-check: new revision, new qualification check, not a carryover from the last one. A buyer bringing on a new supplier should ask for the HS code, PSR and origin evidence at onboarding, the same discipline the first 90 days guide already asks for everything else, rather than waiting for the first export shipment to raise it.
The Takeaway
CETA changed the number on the tariff line. It did not change the amount of proof required to claim it. A buyer who treats "sourced from India" as sufficient is one customs audit away from a retroactive duty bill on an order that already shipped. A supplier who treats "we're CETA-eligible" as a marketing line rather than a per-product calculation is one specific-rule mismatch away from a rejected claim. The suppliers who get their documentation right first and the buyers who verify it before the order rather than after the shipment, are the ones who actually capture the saving this agreement created.

Frequently asked questions
Does CETA make everything from an Indian supplier duty-free automatically?
No. CETA removed duty on 99% of tariff lines, but each product has to independently meet its own Product Specific Rule. A supplier being Indian, or even being generally CETA-eligible on other parts, does not qualify a specific product on its own.
How do I know if my specific product qualifies for CETA's preferential duty?
Look up the Product Specific Rule for that product's HS code in the agreement's tariff schedule (Annex 3A). The rule states whether the product needs a change in tariff classification, a minimum value-addition share, or both.
What is a Product Specific Rule (PSR) under CETA?
The specific origin requirement attached to one HS code. It is not a single blanket rule for all products; every tariff line has its own version, which is why "CETA-eligible" has to be checked per product.
How is qualifying value content (QVC) calculated?
Using either the build-down method (finished product value minus non-originating material value) or the build-up method (adding up what originating materials contributed). The build-up method's threshold is 35%, regardless of value base. The build-down method's threshold depends on the base: 40% on an ex-works value, 45% on an FOB value.
Who issues a Certificate of Origin for goods exported from India to the UK?
Two options, both filed through DGFT's Trade Connect ePlatform since July 15, 2026: a DGFT-authorized agency, an Export Promotion Council, or a designated Chamber of Commerce can issue it, or the exporter can self-declare it electronically using a Digital Signature Certificate linked to their Importer Exporter Code.
Is the certification process the same for UK exports to India as for Indian exports to the UK?
No, and this is the most commonly confused point. Both directions have a self-declaration option, but they are not the same mechanism. UK-origin goods entering India use a CBIC-authenticated self-declaration completed by the UK exporter. Indian-origin goods entering the UK can use either an agency-issued Certificate of Origin or a separate self-declared eCoO generated with a DSC linked to the exporter's IEC. Assuming either side's process is identical to the other's is the mistake to avoid.
Can a buyer lose the duty saving even after a Certificate of Origin has been accepted?
Yes. Authentication confirms the certificate was properly filed; it does not by itself confirm the goods meet the origin rule. Customs can separately verify originating status later, which can result in a retroactive duty assessment even on a previously accepted certificate.
What should a buyer ask a supplier before relying on a CETA duty quote?
The specific HS code, the PSR basis that applies to it, the value-addition calculation behind the claim (not just a certificate number), and which body issued the certificate. All four, checked before the order, not assumed from the supplier's general reputation.
