Authentication of Export Documents

The WTC Denver authenticates or "chamberizes" export documents such as commercial invoices, Certificates of Free Sale, Certificates of Origin and Export Registry Forms.

What is a Certificate of Free Sale?

Upon review the World Trade Center Denver can issue a Certificate of Free Sale for products manufactured and legally sold in the United States. A Certificate of Free Sale states that the company selling the products has submitted evidence to us that the products listed on the certificate are freely sold in the United States.

If the U.S. Food and Drug Administration (FDA) covers your product, we cannot issue a Certificate of Free Sale for you. You must contact the FDA directly and have them issue the certificate.

Why do I need a Certificate of Free Sale?

Many countries are now requiring a Certificate of Free Sale, sometimes called a "Certificate for Export" or "Certificate to Foreign Governments", as assurance from a foreign agency that the products listed on the certificate are freely sold and manufactured in the U.S.

How do I get a Certificate of Free Sale from the World Trade Center Denver?

*Please Read Carefully*(Certificates may be delayed, denied, and include additional costs if requirements below are not met)

  • 1) Please specify for which country or list of countries you would like the Certificate(s) issued (not just regions).
  • 2) You must be able to prove your products were manufactured in the U.S. by submitting a written declaration from the manufacturer (a signed declaration from your company if you are the manufacturer) stating that the products are manufactured in the United States. The declaration must: (1) be on the letterhead of the company requesting the certificate, (2) contain within the declaration the names of the products being certified, (3) include the language "products are manufactured and freely sold in the USA," and (4) include the name of the applicant company.
  • 3) For each product you would like listed on the Certificate of Free Sale, your company must submit copies of invoices showing the sale of each product to two different U.S. customers.
  • 4) The invoices should be dated within the last 12 months and the product names must be the same as how they will appear on the Certificate.
  • 5)* Please specify exactly how the products should be listed on the Certificate(s). This should coincide with how they are listed on the commercial invoice by at least 80% (e.g.: Listed as 'Grape Shampoo' on invoice, but needs to be listed as 'Shampoo, Grape, 16 oz.' on the certificate. An example we cannot comply with would be if 'Grape Shampoo' is listed on the invoice, but needs to be listed as 'Special Volume Control Grape Shampoo' on the certificate).*If the product(s) name you list on the form does not match the invoice product(s) name we will not be able to process the certificate.
