A Form E Certificate of Origin is the document that lets goods exported from Vietnam into China enjoy preferential tariffs under the ASEAN–China Free Trade Area (ACFTA). Yet many exporters see their certificates rejected by the importer or denied preferential treatment by Chinese customs — over basic mistakes in applying for and completing the C/O. This guide walks through the procedure for obtaining a Form E C/O for Vietnam-to-China exports under Circular 12/2019/TT-BCT — which remains in force as of 14 October 2026.
1. What is a Form E C/O and why do exporters need it?
A Form E Certificate of Origin certifies origin under the Rules of Origin of the Framework Agreement on Comprehensive Economic Cooperation between ASEAN and China (ACFTA). When Vietnamese goods arrive in China accompanied by a valid Form E, the importer may apply the ACFTA preferential tariff — usually significantly lower than the MFN rate.
In other words, a Form E does not change the quality of the goods, but it directly determines their after-tax landed cost in China — a decisive factor when competing against goods from other ASEAN countries also leveraging ACFTA.
2. Legal basis: Circular 12/2019/TT-BCT remains in force
The issuance and management of Form E C/Os in Vietnam are governed by Circular 12/2019/TT-BCT of the Ministry of Industry and Trade dated 30 July 2019 (effective 12 September 2019), prescribing the Rules of Origin under ACFTA. It remains in force as of 14 October 2026 and is the only text exporters need to follow.
- Appendix II of the Circular: the Form E specimen;
- Appendix III: box-by-box instructions for completing the C/O;
- Article 33: third-party invoicing;
- The general origin framework: Decree 31/2018/ND-CP dated 8 March 2018 detailing the Law on Foreign Trade Management on rules of origin.
Important note: the Protocol upgrading ACFTA was signed in 2025 but has not entered into force as of the date of writing. Exporters should continue to apply Circular 12/2019/TT-BCT until new guidance is issued. Do not confuse Form E with Form D (ASEAN), Form AK (ASEAN–Korea) or Form AJ (ASEAN–Japan).
3. Origin criteria: the threshold condition for a Form E
Not every shipment to China qualifies for a Form E. The threshold condition is meeting the ACFTA origin criteria:
- WO (Wholly Obtained) — wholly obtained goods (grown, raised, extracted… in Vietnam);
- PE (Produced Entirely) — produced entirely in Vietnam from originating materials;
- RVC (Regional Value Content) — regional value content meeting the prescribed threshold (commonly 40%);
- CTH (Change in Tariff Heading) — tariff-heading change under the applicable Product Specific Rules (PSR).
Exporters must look up the PSR by HS code for each product to identify the correct criterion. A wrongly declared origin criterion is among the most frequently detected errors in post-issuance verification.
4. The application dossier: eight groups of documents
- Application form for C/O issuance, duly completed;
- Form E specimen (Appendix II of Circular 12/2019/TT-BCT), completed per the Appendix III instructions;
- Export customs declaration with clearance completed;
- Commercial invoice;
- Transport documents (bill of lading, airway bill…);
- Detailed schedule of materials used to manufacture the exported goods (to evidence the origin criterion);
- Material consumption norms and production process (for manufactured goods);
- Trader dossier (first-time registration: enterprise registration certificate, specimen signatures…); and any other documents evidencing origin upon request.
5. Seven steps to file on the eCoSys system
The issuing authority for Form E is the Ministry of Industry and Trade (through its regional Import-Export Management Offices), receiving applications via the eCoSys system. Note: for preferential C/O forms such as Form E, exporters do not file with VCCI (which issues only non-preferential forms such as Form B or Form X). The seven steps:
- Register a trader account on eCoSys and register the digital signature and seal;
- Declare the trader dossier (first time) and obtain approval from the issuing authority;
- Create the C/O application on eCoSys with the electronic dossier attached;
- Complete the Form E strictly per the Appendix III instructions — pay special attention to the 13-character reference number: starting with VN (exporting country) + CN (importing country) + the subsequent character groups as prescribed;
- Submit and track: processing time is 6 working hours for online filings and 8 working hours for paper filings (as published on the National Public Service Portal);
- Collect the result: the paper C/O, signed and stamped, is handed to the trader (or delivered by the registered method);
- Deliver the documents to the importer in China for preferential clearance.
6. Five common mistakes that get a Form E rejected
- Inconsistency across documents: product name, quantity or value on the C/O not matching the invoice, transport document or customs declaration — the most common error;
- Wrong origin criterion: declaring RVC where only CTH is met, or vice versa; failing to check the PSR by HS code;
- Third-party invoicing: where a trading company in a third country issues the invoice — it must be declared under Article 33 of Circular 12/2019/TT-BCT with the third party clearly shown on the C/O; omission is grounds for the importing customs to refuse preference;
- Malformed reference number: fewer than 13 characters or wrong VN/CN group order;
- Missing origin evidence: no material schedules or consumption norms retained — a major risk in post-issuance verification, where the competent authorities of both countries may cooperate to verify an issued C/O.
7. After issuance: a 10-point check before handing over the documents
Before sending the Form E to the Chinese counterpart, cross-check ten items: (1) the 13-character reference number in the correct structure; (2) exporter/importer names and addresses; (3) goods description; (4) HS code; (5) origin criterion; (6) quantity and weight; (7) invoice number and date; (8) third-party details (if any); (9) signature and seal of the issuing authority; (10) consistency with the entire export document set. Fixing errors after handover costs far more than correcting them upfront.
