For Customs Authorities
For customs and border agencies accepting or verifying digitally signed trade documents.
What changes
A UNVTD document is standard JSON containing the same trade data as a traditional document, plus a cryptographic signature. It can be verified without contacting the issuer or a central database, validated against a published schema, and parsed as plain JSON — no proprietary format required.
Integration options
| Option | Description |
|---|---|
| API integration | Accept UNVTD documents via existing submission APIs alongside or instead of PDF attachments. |
| Batch processing | Ingest and validate in bulk using published schemas and open-source verification libraries. |
| Manual verification | Verify individual documents using any W3C VC-compatible verifier tool. |
Verifying issuer identity
The issuer field contains a DID. Resolve it to retrieve the issuer’s public key, verify the signature, then check the DID against your existing trust framework (AEO programmes, registered exporter schemes, etc.). No new central infrastructure is required.
Use the conformance test suite to validate documents submitted by traders.
