UK releases updated preferential tariff & Rules of Origin guidance
HMRC has published statutory guidance on the Customs Tariff (Preferential Trade Arrangements) (EU Exit) Regulations 2020, covering the UK's preferential tariffs and Rules of Origin (RoO) for post-Brexit trade agreements. The guidance consolidates reference documents for all preferential arrangements the UK maintains, including the UK-EU TCA and bilateral FTAs. Shippers and customs brokers need this to determine eligibility for preferential tariff rates and to support claims of preferential origin on export and import documentation.

On 20 May 2026, HMRC released statutory guidance on the Customs Tariff (Preferential Trade Arrangements) (EU Exit) Regulations 2020, providing shippers and customs professionals with authoritative reference documents for all UK preferential trade agreements concluded since EU exit.

— HMRC, May 2026
The guidance consolidates technical rules for determining eligibility under the UK's preferential trade framework. This includes:
- Preferential tariff schedules — itemised duty rates for each FTA partner, broken down by HS chapter and product line
- Rules of Origin requirements — the substantial-transformation criteria, cumulation rules, and origin protocols that govern which goods qualify for preferential treatment
- Reference documents — the enabling legislation and implementing instruments for each agreement (UK-EU Trade and Cooperation Agreement, bilateral FTAs with Japan, Australia, Canada, and others)
The regulations apply to goods imported into or exported from the UK under preferential trade arrangements. Shippers claiming preferential rates must ensure goods meet the applicable Rules of Origin—typically requiring minimum percentage local content, specific manufacturing processes, or originating-country inputs—and must maintain supporting documentation (invoices, certificates of origin, supplier declarations) to evidence entitlement.
HMRC clarifies that the guidance supersedes previous temporary notices and applies uniformly across all UK preferential arrangements. The consolidation reflects changes to bilateral FTA negotiations and updates to partner-country schedules since 2020.
Since each FTA partner has distinct rules (e.g., Japan's automotive RoO differ materially from the EU's textile rules), exporters and importers must consult the specific agreement schedules relevant to their product and destination. Failure to apply the correct Rules of Origin can result in tariff re-assessment, penalties, and delays at the border.
What this means for shippers
Verify immediately that all current export and import claims of preferential origin align with the updated HMRC reference documents—misclassification of origin or failure to meet RoO thresholds triggers duty reassessment. Download the relevant FTA schedules for your product and partner country from HMRC's guidance portal, confirm cumulation and local-content percentages with your suppliers, and update your customs declarations and certificate-of-origin templates. Review completed shipments from the past 12 months for any discrepancies; HMRC audits can reach back four years. /hs-codes/search
