Terms of use

Last updated: 2026-06-11

These terms govern your use of Preferential Origin Checker (https://preferential-origin.shipcostlab.com), a free informational tool.

Access

The site is provided free of charge, as-is, for informational use. No account, registration, or subscription is required or offered.

Informational character — no professional advice

The worksheet produces indicative preferential-origin assessments and duty-savings estimates based on simplified, chapter-bucket product-specific rules. It is not customs, tax, or legal advice. The official text of the relevant free-trade agreement and its Annexes remains the only authoritative source. Consult a licensed customs broker or trade counsel before claiming preferential origin on a real customs entry.

Our content

Text, calculations, datasets, and design are owned by the site operator (identified in the legal notice) unless otherwise attributed. You may quote short excerpts with attribution. Commercial reuse requires prior permission.

Third-party references

We cite third-party sources (FTA texts, WTO/WCO materials) for reference. We are not responsible for their availability or for changes made to them after our dataset's last verification date.

Liability

To the extent permitted by applicable law, the operator accepts no liability for decisions taken solely on the basis of the site's outputs. Rules-of-origin annexes change; data may become outdated between dataset verifications.

Changes

We may update these terms. Continued use after an update constitutes acceptance.
