1. When the invoice needs legalization
Common cases.
The destination is not a party to the Apostille Convention and requires legalized commercial documents.
The destination is a party but its customs authority requires legalization of the invoice for a specific product category.
A letter of credit requires a legalized invoice.
2. The chain
For an invoice:
Notarization by a Chinese notary office with foreign-related authority.
Authentication by the Chinese foreign ministry or an authorised local office.
Legalization by the destination embassy.
Three steps.
3. The notarization detail
The notary certifies the invoice.
Where the invoice is a document prepared by the exporter, the notary’s act is the certification of the document as presented, or the certification of the exporter’s signature.
Price of legalization is fixed at the moment the notarial certificate is issued. Changes after that require redoing the chain.
4. Where CCPIT fits
For some destinations, the invoice chain begins with CCPIT certification of the invoice rather than notarization.
Where that applies:
CCPIT certifies the invoice.
The notarized or certified document is authenticated.
The embassy legalizes.
Confirm which starting document the destination requires. Producing the wrong one wastes a cycle.
5. The content requirements
A legalized invoice must be final at the time of notarization.
Elements to confirm before the chain starts:
Exporter and consignee details.
Goods description.
Quantity and value.
Trade term.
Country of origin.
The destination’s own invoice requirements.
6. The translation
Some destinations require the invoice in Arabic, French or Spanish.
Where translation is required, it should be done before notarization, and the notarization should cover the translated version.
7. The invoice and the certificate of origin together
Many destinations require the invoice and certificate of origin to be legalized together, and the embassy checks that they correspond.
Where they do not, both are returned.
Align consignee, description, quantity and value before submission.
8. The timing
Notarization: a few days.
Authentication: a few days.
Legalization: typically seven to ten working days.
Total: two to three weeks.
9. The re-submission problem
Where the destination requires the invoice and certificate of origin together and one is defective, both are returned and both re-legislated.
This is the most expensive form of the problem, because the correct document is invalidated by the defective one.
10. Common errors
Wrong starting document
CCPIT where notarization is required, or the reverse.
Invoice not finalised before notarization
Changes require a new cycle.
Invoice and certificate of origin inconsistent
Both returned.
No translation where required
Rejected.
Underestimating the timeline
Two to three weeks.
11. Closing view
Invoice legalization is mechanical once the chain is correct, and the chain’s correctness is destination-specific.
Confirm the starting document and the content requirements before anything is submitted.
