1. Vietnam and the Convention
Vietnam acceded to the Apostille Convention in September 2026.
Until it takes effect between China and Vietnam, Chinese documents destined for Vietnam require consular legalization: notarization, foreign ministry authentication, and Vietnamese embassy or consulate legalization.
This is a transitional period, and it is where exporters make mistakes in both directions.
2. What to do during the transition
Confirm the current position before each shipment rather than relying on an analysis from last quarter.
Two questions:
Has the Convention entered into force between China and Vietnam as at the date of the intended use?
Does the Vietnamese receiving authority accept apostilled documents yet, or does it require legalization?
Vietnam’s accession and its effective date are separate. The gap between them is the complication.
3. The consular route, while it applies
Notarization at a Chinese notary office with foreign-related authority.
Authentication by the Chinese foreign ministry or an authorized local foreign affairs office.
Legalization by the Vietnamese embassy or the consulate covering the issuing province.
Vietnamese consular districts cover different groups of provinces. Confirm which consulate serves the province where the document was issued.
4. Documents typically requiring legalization
Business licence, for tenders and registration.
Powers of attorney.
Contracts, where the Vietnamese counterparty requires legalization.
Free sale certificates.
Certificates of origin and commercial invoices, where the customs entry requires legalized documents.
Civil documents, including birth, marriage, academic and criminal record certificates.
5. What the import requirement actually is
Vietnamese customs requirements for commercial documentation differ from the embassy’s legalization requirements.
Commonly, Vietnam’s customs entry for Chinese goods requires the certificate of origin and commercial invoice, but not necessarily legalized versions. The legalization requirement more often arises from the Vietnamese counterparty’s registration or tender process than from the customs entry itself.
That distinction matters because it determines whether the legalization cycle is on the critical path. A shipment that needs only the certificate of origin and invoice, unl egalized, does not need to wait for a consular cycle.
Ask the importer what the entry requires, separately from what the embassy will legalize.
6. Timing
Embassy legalization typically takes around seven working days.
With notarization and foreign ministry authentication, a full cycle runs two to three weeks.
After Vietnam’s accession takes effect, the apostille route would reduce this to days. Until then, plan on the consular cycle.
7. The Form E interaction
Vietnam is a party to the China-ASEAN FTA and to RCEP. Most Chinese-origin goods entering Vietnam claim preference under Form E or RCEP.
The certificate of origin is not the same document as a legalized commercial document. Where the importer needs both a Form E for the preference and a legalized invoice for their own registration process, those are two separate workstreams.
8. Common errors
Assuming the Convention already applies
Vietnam’s accession is recent. The effective date and the receiving authority’s readiness are separate questions.
Assuming it does not apply when it does
The opposite error, after the effective date. Documents legalized unnecessarily cost weeks.
Sending documents to the wrong consulate
Vietnam allocates by province.
Confusing customs requirements with legalization requirements
The entry may not need legalized documents at all. Confirm before arranging a consular cycle.
Not accounting for the Form E separately
Preference and legalization are different processes.
9. Closing view
Vietnam is in a transitional position, which makes it a destination where judgement matters more than procedure.
The judgement is simply this: check the current status before each shipment, and check the receiving authority’s readiness separately from the Convention’s legal status.
