For electronics and hardware with global supply chains, origin is rarely obvious. This guide explains the sufficient processing tests, cumulation provisions, documentation requirements, and the audit risks of getting it wrong.

A component at Chapter 85 (electrical machinery) that becomes a different Chapter 85 heading after assembly may qualify. **Tech relevance:** Widely used for electronics — assembly operations that change the tariff heading of inputs can establish origin ### Sufficient processing — specific manufacturing operations **How it works:** Some product-specific rules require specific operations (e.g., wafer fabrication for semiconductors, PCB assembly with local content thresholds) **Tech relevance:** Semiconductors and complex electronics often have specific rules rather than general CTH ### Sufficient processing — value added threshold **How it works:** The ex-works price of the finished product must exceed the value of non-originating materials by a specified percentage (varies by FTA: typically 40–50%) **Tech relevance:** Common alternative rule for products where CTH is difficult to achieve — particularly for final assembly operations in Asia ## Cumulation provisions: why they matter for electronics Bilateral cumulationMaterials originating in the partner country (e.g., Japan under CPTPP) count as originating in the country processing them into the final product. Most common form of cumulation in UK FTAs. Diagonal cumulationMaterials from a third country that is part of the same pan-Euro-Mediterranean system (or equivalent UK system) can count as originating. Relevant for UK-Turkey trade and UK agreements with Mediterranean countries. Full cumulation (CPTPP)Within CPTPP, processing operations carried out in any member country count toward the origin calculation, even if the material does not itself acquire originating status. This is the most flexible form and particularly advantageous for complex electronics supply chains.

No — China is not a CPTPP member. Goods assembled in China, even if they contain components from CPTPP member countries, generally cannot claim CPTPP preferential rates for import into the UK. CPTPP preference requires goods to originate (under the product-specific rules of origin) in a CPTPP member country. If goods are assembled in China using components from Vietnam (a CPTPP member), the goods origin would typically be Chinese, not Vietnamese, unless the assembly in Vietnam itself meets the product-specific rule. ### What is a Registered Exporter (REX) statement and when is it required? A REX statement is an origin declaration made by an exporter registered with their national customs authority (under the EU/UK REX system). For shipments above EUR 6,000 in value, origin must be declared by a REX-registered exporter. Below EUR 6,000, any exporter can make an origin declaration on their invoice. For UK imports claiming FTA preference, check whether the specific FTA requires a REX statement, a movement certificate (EUR.1), or simply an invoice declaration. ### How long must origin documentation be kept for HMRC audit purposes? HMRC can audit preference claims for up to 4 years after the date of import (longer in cases of fraud). Best practice is to retain origin documentation — supplier declarations, REX certificates, EUR.1 movement certificates, cost calculations for value-added claims — for a minimum of 6 years to align with HMRC's general record-keeping period for customs and tax records. Store documentation in a retrievable format linked to the customs entry reference. 🇬🇧 UK roadmap for your product Every standard, document, and test that applies — free, no account required.
