Reading supplier's declarations with AI: origin proofs, EUR.1 and HS codes

In international trade, the proof of origin determines duties, preferences and compliance. But the documents required for it — supplier’s declarations, certificates of origin, EUR.1 certificates — come in countless variants, often as scans, PDFs or paper. Capturing and checking them by hand ties up experienced customs and export staff.

AI-based reading automates this step: the relevant details are extracted in structured form, reconciled against other documents and handed over to customs or ERP systems.

The relevant documents

• A supplier’s declaration is a supplier’s statement about the customs origin of the goods — the basis for preferential proofs, often as a long-term supplier’s declaration (LTSD).
• The EUR.1 movement certificate documents preferential origin under free trade agreements and enables reduced or zero duties.
• The certificate of origin certifies the country of origin of goods and is often issued by chambers of commerce.

A common data field runs through all three: the HS code, which classifies the goods internationally.

What AI does here

An AI model reads these documents template-free and recognises the decisive fields even on unseen layouts:

1. Extract. Country of origin, goods description, HS codes, quantities and referenced documents are captured in structured form — whether the document is a scan, PDF or structured file.
2. Reconcile. The details are checked against commercial invoices, delivery notes and freight documents, so discrepancies surface early.
3. Hand over. The validated data flows into customs software, ERP or accounting — with visual grounding that traces every value back to its original location.

Connecting to freight processing

Proofs of origin rarely stand alone: they belong to a case made up of a freight invoice, customs documents and a delivery note. feld.ai automates customs documents and connects them within freight invoice processing into an end-to-end, auditable process — sovereign and running on our own servers in Austria.
