Certificate of Origin (COO) – What You Need to Know?

When shipping goods internationally—by air or ocean—customs may ask for a Certificate of Origin (COO).

This document confirms where your goods were made and is a key part of many trade and customs processes.

What Is a Certificate of Origin?

A Certificate of Origin proves the country where the goods were manufactured or obtained. t’s usually prepared by the exporter or manufacturer and, in some cases, must be signed and stamped by an authorized body (like a Chamber of Commerce).

Why Is It Important?

  1. Customs Clearance: Helps customs verify if your goods can enter the country.
  2. Tariff Benefits: Determines if your shipment qualifies for reduced or zero import duties under trade agreements.
  3. Trade Restrictions: Proves your goods are not from a restricted or banned country.
  4. Authenticity: Confirms the origin for buyers (e.g., “Belgian chocolates made in Belgium”).

When Do You Need It?

  • Required for many shipments, especially when claiming tariff benefits.
  • Not always needed for small, low-value shipments.
  • Rules vary depending on the trade agreement between countries.

How Customs Checks a COO?

Customs will verify:

  • The COO’s reference number
  • Signatures and stamps
  • Validity date (usually 12 months)
  • Consistency with the invoice and bill of lading

Who Issues It?

  • Chambers of Commerce
  • Customs authorities
  • Trade departments
  • Exporters or manufacturers (if self-certification is allowed)

In Short: A Certificate of Origin is your proof of where goods are made. It helps avoid delays, reduces costs under trade agreements, and ensures your shipment meets customs requirements. At Shippers Bay, we guide you through getting the right COO so your cargo moves smoothly across borders.
