Origin and Preference Audits: Recovering Duty Through Trade Agreements

The average UK textile importer has a 53% preference utilisation gap. That means over half of eligible imports are paying full duty when zero-tariff treatment is available under trade agreements.

What Origin and Preference Audits Cover

An origin and preference audit reviews your FTA eligibility, documentation validity, product-specific rules compliance, and retroactive preference claim opportunities across your TRE declaration history.

FTA Eligibility Review

Identify which of the UK's 70+ trade agreements apply to your supply chain. The TCA, CPTPP, DCTS, and bilateral agreements each have different origin rules, cumulation options, and documentation requirements.

Documentation Audit

Verify that EUR.1 certificates, Statements on Origin, REX registrations, and supplier declarations are valid, complete, and correctly referenced on customs declarations. Incomplete or incorrectly linked documents can invalidate preferential claims.

Product-Specific Rules of Origin

Each FTA defines origin rules at product level:

• Textiles often require a change in tariff heading plus specific manufacturing or processing criteria.
• Automotive products typically face value-added or regional value content thresholds.
• Food products may need to be wholly obtained or meet strict processing rules.

Audits compare your bill of materials, processing steps, and customs classifications against these product-specific rules.

Retroactive Preference Claims

Missed preferences can usually be claimed retroactively within the 3-year C285 window. By analysing TRE data, every declaration where preference was available but not claimed can be identified, quantified, and prepared for refund applications.

How BorderAudit Automates Preference Audits

BorderAudit automates origin and preference audits with:

• REX validation to confirm exporter registrations and status.
• Document intelligence to read and validate EUR.1s, Statements on Origin, and supplier declarations.
• Automated preference analysis across your TRE declaration history to flag every missed opportunity.

With a 53% preference gap in textiles alone and GBP 4.7M recovered to date, automated audits turn complex FTA rules into measurable duty savings.
