What Is a Certificate of Origin?

A Certificate of Origin (CO) is an official document that identifies the country in which goods were produced, manufactured, or substantially transformed.

Customs authorities in many countries use the Certificate of Origin to determine the applicable customs treatment, verify the origin of goods, and apply trade agreements or trade policy measures where appropriate.

For international businesses, the Certificate of Origin is one of the most important documents used in global trade.

Why Is a Certificate of Origin Important?

A Certificate of Origin helps businesses:

Verify the country of origin
Support customs clearance
Meet import requirements
Facilitate international trade
Support claims under applicable trade agreements
Improve customs documentation accuracy

Some destination countries require a Certificate of Origin before imported goods can be cleared through customs.

When Is a Certificate of Origin Required?

The requirement depends on several factors, including:

Destination country
Product category
Import regulations
Applicable trade agreements
Customer requirements

Not every international shipment requires a Certificate of Origin.

Information Included in a Certificate of Origin

Although the format may vary, a Certificate of Origin generally includes:

Exporter information
Importer information
Country of origin
Product description
Quantity
Packaging details
Commercial invoice reference
Certification details

The information should match the accompanying commercial documents.

Certificate of Origin vs. Preferential Origin Documents

A standard Certificate of Origin should not be confused with preferential origin documents.

Preferential Origin Documents
