In international trade, many countries require that trade documents must be certified by a competent Chamber of Commerce in the place of documents issuance to ensure their legitimacy before they can be accepted as valid. The Hong Kong General Chamber of Commerce (HKGCC) is a worldwide trusted organization providing certification of documents service.

Almost all business documents can be certified by the chamber. The Chamber provides certification of documents for export invoices, B/L and AWB, packing lists, etc. and endorsement of documents for company registry, business registration certificate, trade mark certificate, laboratory reports, etc.

Submit an 'Application and Declaration Form' (CDA or CDB) and the invoice to be certified in two copies. A photocopy of business registration certificate is also required for verification of applicant’s identity.

It takes 4 working hours to complete the issuance. One hour expeditious service is also available to those with urgent needs.
