A UK exporter puts its GB EORI in the statement. The saving also relies on the goods really meeting the rule.

The origin has to be on the [invoice](/resources/commercial-invoices), and a USMCA claim has to be backed by a certification. Some specific programmes have their own requirements, so check with your [broker](/directory/customs-brokers)."},{"question":"Can I get a certificate after shipping?","answer":"Sometimes. For EUR.1 deals, there's a route for certificates issued retrospectively, and self-declarations can often be added later if the agreement allows. Under the EU-UK deal, a claim can be made [within 3 years of importation](https://www.gov.uk/guidance/proving-originating-status-and-claiming-a-reduced-rate-of-customs-duty-for-trade-between-the-uk-and-eu).
