One document, many hands, zero drift.
Bills of lading, certificates of origin and inspection reports pass through many hands. Every party in the chain can verify it holds the same untampered document the issuer sealed at the start.
What gets sealed
Sealed at issuance by the carrier, so quantity and condition claims stay fixed across the voyage.
Anchored when certified, defeating substitution at borders and in tariff disputes.
Sealed at inspection, so downstream buyers see exactly what the inspector wrote.
How it runs day to day
The issuer seals the document the moment it is created.
The document travels its normal path: email, EDI, portals.
Each intermediary can verify it against the chain on receipt.
At destination, customs or the buyer confirms it is the original, untouched.
A cargo arrives with an inspection report claiming a higher grade than the goods show. The report fails verification: it is not what the inspector sealed. The genuine report verifies, and liability lands where it belongs.
Paper trails across jurisdictions are where tampering hides best; a chain-anchored fingerprint travels better than any stamp.
