The Certificate of Origin (CO) is an essential document in import customs clearance to declare a country where a commodity or good was manufactured, which hastened the customs clearance process.
The legalization sticker proves the authenticity of the CO document to use in the custom clearance process and as evidence in the importer court.
There have been recent cases of counterfeit Certificates of Origin, which may negatively impact business operations and international trade. To ensure that you are using a valid document, we strongly recommend that you verify its authenticity before conducting any transactions. You may refer to the sample provided below as a preliminary guideline for document verification.
To verify whether a Certificate of Origin (CO) or a Legalization sticker has been genuinely issued by the Thai Chamber of Commerce, please refer to the official document format shown below.
If the document does not match the official format, it should be presumed inauthentic. You may verify its validity by submitting the Certificate No. to the Export Document Certification Department via email at co_online@thaichamber.org, where our team will assist in verifying the document.
