REX registration, proof of origin

Hi all, Is there a list of countries anywhere that require REX registration as a proof of origin please for duty relief? I know about India, Pakistan and obviously the EU, but is there any other countries that you have to have a valid REX number from that country to apply duty relief? Google is no help at all. Thanks

For imports into the UK the only country / territory where a REX registration number needs to be shown on the statement on origin is the EU. When the UK left the EU it lost access to the REX system which is an EU scheme. The acceptable proofs if origin for UK agreements are listed in the online UK tariff schedule . https://www.trade-tariff.service.gov.uk/rules_of_origin/proofs Where a statement on origin is an acceptable proof then the exporter number will be needed . Depending on the agreement it may be the exporter tax registration number or an approved exporter number. An approved exporter number is not however the REX number.

Thank you, that's really helpful.

Hi lisacustoms,
REX is no longer issued to the traders established in GB (except NI traders) and there is no list available on gov.uk.
Customer can check resources published by EU such as below link.
REX – Registered Exporter system
Thank you.
