Preferential and Non-Preferential Origin
Analysis of origin rules to correctly manage tariff preferences, origin declarations, Made in requirements, proofs of origin and customs documentation.
Origin, Made in & Preferential Agreements
From substantial transformation and list rules to cumulation, proofs of origin and free trade agreements.
Origin is not simply the country of shipment
Rules of origin determine the economic nationality of goods. A correct analysis requires customs classification, materials used, processing operations performed, list rules, trade agreements and available documentation. An error may affect duties, trade-policy measures, proofs of origin, Made in requirements and declarations made to customers.
Non-preferential origin: wholly obtained goods and last substantial transformation
Where only one country is involved in production, the analysis concerns wholly obtained products: for example goods harvested, extracted, born and raised, or otherwise wholly obtained in that territory under the applicable rules. Where two or more countries are involved, the place of the last substantial transformation must instead be identified.
List rules and Annex 22-01
For goods covered by EU list rules, the product’s CN classification is used to identify the relevant technical criteria, including through Annex 22-01 to the Union Customs Code Delegated Regulation. Minimal operations that, by themselves, do not confer origin must also be considered.
Preferential origin: sufficient working, cumulation and free trade agreements
Preferential origin may allow reduced or zero customs duties where the conditions of the applicable agreement are met. The analysis is not limited to the country of production: the product-specific rule, sufficient working or processing, any insufficient operations and the cumulation possibilities provided by the agreement must be checked.
Bilateral and diagonal cumulation
Bilateral cumulation may allow certain materials originating in the other party to the agreement to be treated as originating. Diagonal cumulation may extend the mechanism to several countries linked by compatible rules, as under the Pan-Euro-Mediterranean system when the relevant conditions are met.
- PEM and the Pan-Euro-Mediterranean Convention
- CETA and other EU free trade agreements
- FTAs, rules of origin and list rules
- REX and Approved Exporter
- EUR.1, EUR-MED and origin declarations
- statement on origin and proof of origin
Proofs of origin and documentation
The appropriate proof depends on the applicable regime and agreement. AEO C Trades reviews consistency between the origin rule, bill of materials, processing operations, supplier declarations and the document used to claim preferential treatment.
- certificate of origin
- origin declaration
- statement on origin
- EUR.1 and EUR-MED
- REX and Approved Exporter
- supplier declarations and long-term supplier declarations
2026 developments on non-preferential origin
From 1 July 2026, Implementing Regulation (EU) 2026/1422 updated procedures concerning evidence of non-preferential origin, including the acceptance of electronic certificates in the relevant special regimes and new documentary rules for certain goods originating in the United States. The applicable requirements must be assessed case by case and in relation to the relevant customs measure.
Melt & Pour: connected to origin, but distinct
For certain steel imports, from 1 October 2026 the country of melt and pour must also be evidenced. The Melt & Pour concept does not replace customs origin: it is a specific metal-traceability requirement that must be managed together with classification, documentation and rules of origin.
