Commercial Invoice Apostille for Opening an Overseas Bank Account in Vietnam
The Situation
A family office in Shenzhen came to us with the intake deadline three weeks out, preparing a corporate account file for account opening in Vietnam.
The commercial invoice had been notarized and apostilled. It was then examined by the bank compliance team, and the objection was not about the Apostille seal. It was about what the earlier stage had certified — the invoice is a private document, so it needs CCPIT commercial certification before an Apostille can attach.
What Actually Went Wrong
Vietnam is not covered by the Convention for China until 11 September 2026.
In this case the gap was narrower: the invoice is a private document, so it needs CCPIT commercial certification before an Apostille can attach. Everything downstream was procedurally correct and substantively useless, because the receiving side needed the fact and had been given the form.
Vietnam requires consular legalisation until the Convention takes effect.
How It Was Resolved
The fix ran through the CCPIT commercial certification of the invoice rather than through the Apostille stage. Once that record was in hand, the notarization could certify the invoice must be stamped by the issuing company before CCPIT will certify it, and the Apostille attached to it meant something.
The redo took five to ten working days at the Apostille stage on top of the time needed to retrieve the record. Because account opening can absorb some delay, the recovery fit inside the original schedule.
The General Rule
Three things decide whether a commercial invoice clears account opening in Vietnam:
One, the invoice is a private document, so it needs CCPIT commercial certification before an Apostille can attach.
Two, the invoice must be stamped by the issuing company before CCPIT will certify it.
Three, Consular legalisation takes three to four weeks, far longer than the Apostille route.
The Apostille stage itself is the predictable part — five to ten working days, no surprises. The surprises all sit upstream and downstream of it.
Check These Before You Submit
- Confirm what the bank compliance team in Vietnam requires, in writing, before notarizing
- Check that the notarization certifies the fact — the invoice is a private document, so it needs CCPIT commercial certification before an Apostille can attach
- Verify the invoice must be stamped by the issuing company before CCPIT will certify it
- Have the CCPIT commercial certification of the invoice ready before the notary appointment
