How to obtain a certificate of origin

What it certifies and what it does not

The certificate of origin issued by a chamber of commerce certifies the non-preferential origin of the goods: which country they are from, under the general rules of origin. It is used for labelling, for statistics, for public tenders, to satisfy a requirement of an importer or a letter of credit, and to evidence origin at destinations that simply demand it.

What it does not do is lower duty. Tariff reduction comes from preferential origin, and that is evidenced with a different document: a statement on origin on the invoice, a EUR.1 or an A.TR depending on the agreement. Confusing the two is the most common misunderstanding of the whole procedure.

One shipment can need both: the preferential one so your customer pays less duty, and the chamber’s one because their bank or their administration asks for it.

How it is applied for

  1. Check it is really being asked forAsk your customer who requires it: their customs, their bank under the letter of credit, or a tender specification. If nobody asks for it, it is a cost and a formality that adds nothing.
  2. Gather the documentationThe commercial invoice for the shipment and, depending on the chamber, a manufacturer’s declaration or purchase invoices evidencing origin. If you are not the manufacturer, you need your supplier to declare it to you in writing.
  3. File the applicationAlmost every chamber now does this online. You complete the form with the same data as the invoice and attach the documentation.
  4. Collect or download the certificateThe chamber stamps and returns the original, on paper or with an electronic signature. Allow one or two working days, and more if it is the first time or supplier declarations have to be produced.
  5. Legalise it if the destination requires itSome countries additionally require consular or foreign-ministry legalisation. That step comes after the chamber’s endorsement and adds several days.

What slows the procedure down

  • Asking for it the day before loadingThe chamber has deadlines and opening hours, and if a supplier declaration is missing the file stops. A week of margin is reasonable.
  • Declaring EU origin for something that is only packaged hereOrigin does not depend on where something is packaged or shipped from. If the processing is not sufficient, the origin is the product’s.
  • Data differing from the invoiceThe chamber endorses against the invoice. Any difference in description, weight or amount sends the application back.
  • Assuming it lowers dutyIt does not. If preference is what you are after, what you need is proof of preferential origin, which is a different document.
