The preferential 0% duty in UK–EU trade is not automatic: the goods must meet a rule of origin under the TCA and have proof of origin — a statement on origin from the exporter or the importer's knowledge. Simply buying goods in the UK or EU does not decide their origin.
Contents
Rules of origin between the UK and the EU come up every time a company wants to use a customs preference or avoid an unnecessary duty cost. Many teams treat origin as a simple statement on the invoice, rather than something to check in advance to confirm the goods actually meet the rules.
This article explains when origin matters, what needs to be checked, and why simply buying goods in the UK or the EU doesn't automatically give a right to preferential treatment.
When rules of origin genuinely matter
This becomes crucial whenever an importer or exporter wants to use the preferential duty rate under the trade agreement (the TCA). GOV.UK guidance is clear: the goods have to be covered by the agreement, meet the relevant rule of origin and be accompanied by the correct proof of origin. A preference means 0% duty only for goods that genuinely have preferential origin — not for everything shipped between the UK and the EU.
The most common wrong assumption
A company assumes that because the goods were bought in the United Kingdom or the European Union, they automatically have preferential origin. What matters is not just where the goods were sold, but where and how the product was made, and whether it meets the rule under the agreement for its commodity code. See how to determine the origin of goods.
What proof of origin you need
In UK–EU trade the preference is proved by a statement on origin made out by the exporter, or by the importer's knowledge that the goods are originating. An EU exporter making out statements for consignments worth more than €6,000 in total needs a REX number (GOV.UK). EUR.1 certificates are not used in this trade. More detail is in statement on origin and the REX system; for products with supplier components, a supplier declaration of origin helps.
What to check in practice
- Whether the goods are covered by the relevant trade agreement.
- Which rule of origin applies to the specific commodity code.
- Whether the product meets the origin condition for that rule.
- What proof of origin will be needed at clearance.
- Whether the commercial declaration and the company's documents support that status, and will be kept for the required period (exporter — at least 4 years; importer — at least 3 years under the TCA, and 4 years in the UK per HMRC).
Why this comes back at clearance
Because it is exactly at the declaration stage that you have to answer whether the preference is justified and whether the documents back it up. If the team hasn't checked beforehand, the problem only surfaces when a quick decision is needed: pay the full duty, or try to assemble documentation under time pressure.

Frequently asked questions
Do goods bought in the UK always have UK origin?
No. Where goods were bought does not determine preferential origin — what matters is where and how they were made and whether they meet the rule of origin for their commodity code.
What proof of origin does the UK–EU agreement accept?
According to GOV.UK, a statement on origin made out by the exporter, or the importer's knowledge that the goods are originating. EU exporters making out statements for consignments worth more than €6,000 need a REX number. An EUR.1 certificate is not proof of origin in this trade.
Can you claim the preference without proof of origin?
In practice, no. At clearance you must be able to document your right to the reduced rate — by an exporter's statement or by the importer's own knowledge and records. Without it you pay duty at the normal rate. If no preference claim was made at import, one can still be made later — no more than 3 years after importation and with a valid proof of origin; the excess duty is then refunded (Article 55(2) TCA; GOV.UK).
How long must origin records be kept?
Under the TCA (Article 59) an exporter keeps a copy of the statement on origin and the supporting records for at least 4 years from the date it was made out, and an importer claiming preference keeps its records for at least 3 years from importation. An importer in the UK keeps records for 4 years from importation according to HMRC guidance. Older records can be used in a criminal investigation. The retention period is not the same as the validity period of a statement on origin.
When is the best time to check the rules of origin?
Before you send the commercial offer, before you ship and before you issue the documents — not only at clearance. That is when you can still change a component source or revisit the price calculation.
