The Certificate of Origin (C/O) is one of the essential documents in import-export activities. However, for a C/O to be legally recognized and used abroad, businesses must undergo the consular legalization process. The following article provides a detailed guide on the consular legalization of Certificates of Origin (C/O), from document preparation to completion at the foreign embassy.
Purpose of Consular Legalization of Certificates of Origin (C/O)
In the context of globalization and growing international trade, the demand for using Certificates of Origin (C/O) between Vietnam and other countries is steadily increasing.
Specifically, many individuals need to legalize Certificates of Origin issued by foreign authorities for use in Vietnam, or conversely, certify documents issued by Vietnam for use abroad. This procedure is particularly common in cases related to migration, marriage, or import-export activities.

Consular Legalization of Certificates of Origin Issued by Foreign Authorities for Use in Vietnam
Consular legalization is the process of verifying the validity of signatures and seals on Certificates of Origin issued by foreign authorities. Once legally confirmed, the document is recognized for official use in Vietnam.
Depending on the country and specific requirements, this procedure can be carried out either in Vietnam or in the country that issued the certificate.
Step 1: Consular Certification at the Embassy or Consulate of the Issuing Country
- The applicant must bring the Certificate of Origin along with a translation into Vietnamese or English (if the document is not originally in one of these languages) to the consular office of the issuing country in Vietnam, or to a diplomatic authority authorized to perform consular certification.
- The documents will then be reviewed and stamped with the consular certification seal.

Step 2: Apply for Consular Legalization at Vietnamese Authorities
After completing the consular certification, you need to prepare and submit your documents to:
- Consular Department – Ministry of Foreign Affairs of Vietnam (40 Trần Phú, Ba Đình, Hanoi)
- Ho Chi Minh City Department of Foreign Affairs (6 Alexandre de Rhodes, District 1)
The profile includes:
- Application form for consular legalization/certification (according to the prescribed template)
- Original and copy of personal identification: valid citizen ID or passport
- Original and copy of the Certificate of Origin that has been consularly certified by the foreign authority
- Other related documents if specifically required by the receiving authority
Once the procedure is completed, the Certificate of Origin issued abroad will be legally valid for use in Vietnam in transactions, administrative procedures, or commercial activities.

Consular Legalization Procedure for Certificates of Origin Issued in Vietnam for Use Abroad
The Certificate of Origin (C/O) is an important document in export activities, indicating the origin of goods. When this certificate needs to be used abroad (e.g., for customs clearance, preferential tariff benefits, or participating in international tenders), it must undergo consular certification. This involves verifying the validity of signatures and seals on the document by the competent authority in Vietnam, followed by legalization at the foreign embassy or consulate in Vietnam.
Detailed Steps of the Procedure:
Step 1: Prepare Initial Documents
- Original Certificate of Origin issued by the competent authority in Vietnam, such as the Vietnam Chamber of Commerce and Industry (VCCI) or other authorized agencies.
- Certified translation into English or the language of the country where the document will be used (depending on the receiving country’s requirements).
Note: Some countries only accept translations certified by a judicial authority, so it is important to check the specific requirements beforehand.
