e-Customs Proof
Make your compliance verifiable.
e-Customs Proof helps marketplaces and online sellers certify customs and VAT data and ensure a full control from online product to customs clearance in Europe.
What’s the real cost of unverified data?
In cross-border e-commerce, customs brokers often rely on fragmented, unverifiable information — especially with FBA, where sellers don’t always know how to deal with customs clearance. But under EU law, you’re still responsible for what and how it is declared.
“More than 80% of parcels inspected by customs show data mismatches. That’s exposure you can’t afford — to penalties, delays, and lost trust.”
e-Customs Proof secures your data with verifiable credentials
e-Customs Proof is a blockchain-based application that certifies that you are the owner of the real customs data, such as value, VAT / IOSS and EORI before the shipment leaves, then link that certified information to the declaration filed by your broker or forwarder.
Throughout the process, you retain verifiable proof of compliance — without exposing any sensitive commercial and private data.
How it works
Whether you manage logistics yourself or ship through forwarders or your FBA, e-Customs Proof helps you take control of your customs data and gives you visibility on customs clearance status and duties amount.
Certify your product and value data
Upload or connect your shipment info — via Excel, API or Amazon — and structure it as a verifiable credential (EBSI-compliant).
Bind your data to the customs flow
Your credential is linked to the shipment ID or declaration — ready for your logistic suppliers.
Prove your compliance
A tamper-proof, audit-ready record is generated — and can be shared on demand with EU customs or VAT authorities.
Make compliance verifiable
e-Customs Proof turns sensitive commercial and private customs data into verifiable credentials — enabling marketplaces and authorities to prove compliance, without exposing raw information.
Verifiable credential generation
Turn IOSS numbers, declared values and descriptions into certified EBSI-compatible credentials (B2C). FBA shipment under control with your EU entity certified with EBSI (B2B).
FBA-ready binding mechanism
Link certified data to declarations, even when logistics are handled by third parties.
Tamper-proof audit trail
Secure, timestamped records — ready for inspection. You make sure your data are well received by authorities.
Privacy-preserving data sharing
Share proof, not raw data — keep your margins and strategy confidential. Sellers keep control on their sensitive commercial data without compromise.
In cross-border e-commerce, trust isn’t just earned — it’s documented.
Prove your compliance
Certify your data before the declaration is even submitted.
Lower your risk exposure
Share consistent, verifiable data — even via third-party brokers.
Protect your marketplace reputation
Avoid blocked goods, delayed deliveries, or customs / VAT penalties.
