India–UK CETA is live: the exporter's 90-day playbook

By Ben Tharakan · THX Ventures LLP · August 2026 · 5 min read

On 15 July 2026, the India–UK Comprehensive Economic and Trade Agreement entered into force. Roughly 99% of Indian export lines now enter the UK duty-free — processed foods that carried tariffs of up to 70%, marine products up to 21.5%, engineering goods up to 18%, textiles up to 12%. India–UK trade was already US$25 billion in FY26; the government's stated ambition is to double the corridor by 2030.

I have spent 25 years clearing cargo, and I will tell you what the press releases will not: the duty cut is real, but it is not automatic. The benefit belongs to exporters who get three unglamorous things right in the next 90 days.

1. Master self-certification before your first shipment

CETA does not use agency-issued certificates of origin. It runs on self-certified origin declarations — a specific wording on your commercial documents, backed by CBIC's Rules of Origin notified in July 2026 (Circular 33/2026-Customs). Your UK buyer claims zero duty on the strength of your declaration.

That transfers the compliance risk to you. Get the declaration wording wrong, or fail the product-specific rule of origin, and the preference can be denied — with your buyer facing retrospective duty and remembering exactly whose paperwork caused it. Register the process properly, document your value-addition math per HS line, and keep the origin file as carefully as the invoice.

2. Reprice with the duty saving in the open

A 12% tariff disappearing does not mean 12% more margin for you. Sophisticated UK buyers — the supermarket groups moved on day one; over 50 consignments worth US$140 million shipped under CETA in the first 24 hours — will negotiate for a share of the saving. Decide your split before they decide it for you: our practice is to lead with a sharper landed price on the first order and hold margin on the reorder, because reliability, not the opening discount, is what a UK category buyer actually pays for.

3. Fix the non-tariff layer now

Zero duty does not waive UK food safety, labelling or standards requirements. For F&B exporters that means UK-compliant labels, health certification where applicable, and shelf-life planning for a longer retail chain. For textiles and leather, it means testing and REACH-adjacent chemical compliance. The exporters who treated ratification year as preparation year are shipping now; the ones who waited are discovering that a certification queue does not care that the tariff is zero.

The 90-day sequence we run for clients

• Weeks 1–2: HS-line audit — confirm each SKU's CETA rate, rule of origin and value-addition position in writing.
• Weeks 2–4: Origin-declaration process set up; export documentation templates updated; first declarations reviewed by a second pair of eyes.
• Weeks 3–6: UK buyer outreach with revised CIF pricing and a one-page spec book per SKU — buyers shortlist on documentation speed.
• Weeks 6–12: First shipments; post-clearance review of each origin file; reorder pricing locked.

The window is open. In our trade, being contracted and compliant in the first quarter of a duty window is worth more than a year of marketing afterwards.
