Trademark Registration Certificate Apostille for Vietnam

The Situation

Sending a trademark certificate to Vietnam looks like a two-step job: notarize, then apostille. In practice there are three points where the file stops moving, and all three sit outside the Apostille stage.

Vietnamese consulates examine the document differently from a Chinese notary office, and the difference is what causes the returns.

What Actually Went Wrong

First stop: the certificate must reflect the current register state, and any assignment, renewal or change of name since registration makes it stale.

Second stop: the goods and services classes must match the register exactly, since abbreviated class lists are rejected.

Third stop: Vietnam requires consular legalisation through the embassy until the Convention takes effect.

How It Was Resolved

Work the three in order and the Apostille becomes the easy part.

Get the CNIPA trademark register extract first. Then have the notary certify the fact rather than the copy. Then verify the name and date details against the receiving requirement. The Apostille attaches at the end and takes five to ten working days.

Vietnam is not covered by the Convention for China until 11 September 2026, so consular legalisation is the only route before that date. That means the text of the notarization is read, not just the seal — which is why the order matters more than the effort.

The General Rule

For Vietnam specifically, Consular legalisation takes three to four weeks, far longer than the Apostille route.

The general rule: the Apostille certifies that a signature and seal are genuine. It does not certify that the document says the right thing. Everything the receiving authority needs to be true has to be true before the seal goes on.
