The certificate of origin is a document in which the economic origin of an exported product is mentioned. Although normally validated by the Chamber of Commerce, in the case of diamonds, it can be validated by the Diamond Office. (Note: The certificate of origin must not be confused with the Kimberley Process Certificate!)

Blank application forms to apply for a certificate of origin can be obtained at the Diamond Office in Antwerp (when abroad, it can be obtained at the local Chamber of Commerce).

The main documents, which must be submitted with the application, are the following:

• Purchasing invoice mentioning the origin of the product;
• Supplier’s declaration (long term declaration);
• Supplier’s certificate of origin;
• Form  A
