How to obtain a C/O, form by form

The FTA rate only applies when the shipment carries the right proof of origin. Since 5 May 2025 every C/O — preferential and non-preferential — is issued by the regional Import-Export Management Offices of the Ministry of Industry and Trade (Decision 1103/QĐ-BCT); VCCI no longer issues C/O or REX numbers. Applications are filed online on eCoSys.

The process, in five steps

  1. Register your trader profile on eCoSys (ecosys.gov.vn) — done once, reused for every later application.
  2. Determine the goods' HS code and its origin criterion under the intended agreement — open the code's page on this site and check the Origin tab.
  3. Prepare the file: application form, the completed C/O, commercial invoice, export customs declaration, bill of lading, and a materials breakdown with evidence for the criterion (material purchase invoices, consumption norms, production process — depending on WO, CTC or RVC).
  4. File online on eCoSys, choosing the right form from the table below; a complete application is typically granted within hours to a few working days.
  5. Send the C/O to the buyer to lodge with the IMPORTING country's customs — a C/O is typically valid for 12 months from issue.

Which form for which agreement

The same form is used in both directions: Vietnam issues it for exports, and the partner country's authority issues it for goods entering Vietnam (the EVFTA and UKVFTA are the exception — see their notes). The origin-criterion column links to the circular whose annex sets the rules.

Goods bound for Korea have three parallel routes: AKFTA (form AK), VKFTA (form KV) and RCEP.

CPTPPCPTPP Agreement

Vietnam issues the CPTPP form during its transition period; several member countries already accept exporter or importer self-certification on their own timetables.

DASEAN (ATIGA)

e-Form D is transmitted through the ASEAN Single Window — the importing customs receives it electronically. Certified exporters may self-certify under the AWSC scheme instead of a C/O.

EUR.1Vietnam - EU (EVFTA)

Vietnam issues EUR.1 for exports to the EU; consignments up to EUR 6,000 may carry an origin declaration on the invoice instead. The reverse direction has NO paper C/O: EU goods entering Vietnam use self-certification by EU exporters registered under REX.

Circular No. 14/2026/TT-BCT
EUR.1 (UK)Vietnam - UK (UKVFTA)

Same mechanism as the EVFTA: EUR.1 (UK version) for exports, invoice declaration up to EUR 6,000, and UK goods entering Vietnam use UK exporters' self-certification.

One form for all 15 members, but Vietnam's RCEP rates are split by COUNTRY GROUP — for the same code, the rate for China, Korea, Japan, ASEAN and Australia/NZ can differ; the rate follows the origin country on the C/O.

Non-preferential C/O (form B)

Form B does not reduce any duty — it only certifies Vietnamese origin when the buyer or the importing country requires proof (letters of credit, trade-remedy screening…). It follows Vietnam's non-preferential origin rules (Decree 31/2018/NĐ-CP) and, since 5 May 2025, is issued through the same MOIT offices and eCoSys as the preferential forms.

Reference guide, not legal advice — the binding texts are Decree 31/2018/NĐ-CP and each agreement's origin circular. Criterion notation (WO, CTH, RVC…) is explained on the rules-of-origin page.
