What a Digital Product Passport actually is

A Digital Product Passport is not a new form to fill in. It is a permanent digital record attached to a batch of goods that anyone along the supply chain can read and verify.

Think of a Digital Product Passport the way you think of a logbook that travels with your shipment. Every important fact about the product — where it was grown, who grew it, what was applied to it, how it was transported — is recorded in one place. Crucially, once recorded, no one can quietly change those facts without the system detecting it.

The passport itself is a digital file — a structured record that can be read by computers, not just humans. This is what allows EU customs systems to check it automatically, without a human auditor having to review every page of a paper file.

Each passport has a unique ID and is linked to an entry on a public digital ledger. The ledger acts like a fingerprint registry: it doesn't store the full record, but it stores a mathematical fingerprint of it. If the record is ever changed after the fact, the fingerprint no longer matches — and the tampering is detected immediately.

Data is collected at the source

GPS location, pesticide records, soil readings, and transport temperatures are recorded as the shipment moves from farm to port.

A fingerprint is taken and locked

The data is fingerprinted and stored on IOTA — a free public blockchain. This creates a permanent, tamper-proof reference that cannot be deleted or altered.

Compliance is checked automatically

Software reads the data and checks it against EU rules — pesticide limits, deforestation-free location, safe temperatures. No human sign-off needed.

The passport is issued

If all checks pass, a Digital Product Passport is created — a unique certificate with a QR code that any EU buyer or customs official can scan to verify.

What makes this different from a PDF certificate is verifiability. A PDF can be forged. A DPP linked to a public blockchain cannot — because anyone can independently check whether the fingerprint matches, without having to trust the exporter.

This is precisely what EU buyers and customs authorities are asking for: not trust, but proof.

Key takeaway

A Digital Product Passport is a machine-readable, tamper-proof digital record that travels with your shipment and proves — to anyone who checks — that your goods meet EU standards. TRACE generates this automatically.
