A Certificate of Origin (COO) is an essential document in international trade. Issued by the exporter, it verifies that a product was manufactured in a specific country. The COO also includes details about the product, its destination, and the exporting country. Many international trade agreements require this document to determine whether goods qualify for import and what duties apply.
Is a Certificate of Origin Mandatory?
Yes, a COO is mandatory. Customs officials require it as a separate document from the commercial invoice and packing list. The COO must be:
- Signed by the exporter
- Notarized
- Endorsed by the local chamber of commerce
In some cases, Customs may also request additional verification from a specific chamber of commerce.
While some countries have flexible COO requirements, others impose strict regulations, requiring specific formats, third-party certifications, and other conditions. The COO is presented to Customs at the destination to confirm the country of origin. If a Free Trade Agreement (FTA) exists between the countries, the COO can lead to lower import duties.
For example, Free Trade Agreements between the United States and other countries often require additional proof of origin. Customs authorities can confirm whether goods qualify for preferential duty rates, such as under the USMCA (United States-Mexico-Canada Agreement).
How to Obtain a Certificate of Origin
- Complete and notarize the required affidavit.
- Provide a Manufacturer’s Invoice or Commercial Invoice showing the place of manufacture.
- Fill out a Certificate of Origin form.
- Submit the notarized affidavit, COO form, and invoices to your local chamber of commerce for stamping. Be sure to specify which documents need authentication.
Preferential vs. Non-Preferential COOs
In the heavy equipment sector, it is vital to distinguish between these two types. A Non-Preferential COO (a Generic COO) simply states where the machine was made for statistical purposes or to comply with embargoes. It does not reduce tariffs.
Conversely, a Preferential COO is linked to a specific trade agreement (like USMCA or CAFTA-DR) and is the golden ticket that eliminates duties. You must not use a generic template when claiming FTA benefits; doing so will result in a claim rejection.
Electronic Certificates (eCO)
Historically, runners had to physically courier documents to the Chamber of Commerce. Today, the Electronic Certificate of Origin (eCO) saves massive amounts of time. You can upload your affidavit and invoice to an online portal, and an accredited Chamber will digitally stamp and sign the document, returning a printable PDF in hours rather than days.
For urgent air freight shipments of spare parts (like a critical hydraulic pump needed to fix a downed crane), using an eCO process can cut days off the transit time.
Dealing with Kits and Assembled Machinery
A common headache involves shipping kits or disassembled machinery (Knock-Down units). If you ship a crane in three separate containers — one for the boom, one for the cab, one for the tracks — the COO must match the Bill of Lading. Some countries require a separate COO for each container, while others allow one set COO. Always verify with the receiving broker before the ship sails.
