Classify any product to the 6-digit HS subheading — the code that is identical in all 200+ WCO member countries

Every answer is grounded in the General Rules of Interpretation, the Section and Chapter Notes, and — where available — real customs rulings, and shows its reasoning. Accuracy still depends on how completely the product is described, and on cases genuinely sitting on a boundary between two headings. That is why we flag "boundary" cases explicitly instead of forcing a single confident answer.

We do not store the product descriptions you submit for classification. AI calls can also be made using your own API key, so your data can go directly to your chosen AI provider rather than through ours.

No. A1 HS provides decision support, not a customs ruling. Only a competent authority can issue a binding classification. Use A1 HS to prepare your reasoning and identify supporting rulings, then verify everything before you file or apply.

A lookup tool returns a heading if you already know roughly where to search. A1 HS reads a plain-language product description, applies the General Rules of Interpretation and the Section and Chapter Notes, checks it against real customs rulings, and explains which rule and which ruling led to the result.

A general model will give you a code and sound certain. It has no access to the actual tariff schedule, so anything below 6 digits is guesswork, and it cannot point you to a ruling that exists. A1 HS reads the real schedule for the country you choose, cites the WCO legal texts it relied on, and attaches customs rulings you can open and read.

You still get the 6-digit HS subheading, which is identical worldwide and is the level most classification disputes turn on. National tariff lines and rulings are added one country at a time — see the coverage table above for what is live today versus on the roadmap.

You can connect your own API key from your AI provider. You pay that provider directly at their rates, and detailed opinions generated with your own key are unlimited — we don't mark up the AI cost.

Some products genuinely sit between two plausible headings — like the marble slab example above. Instead of guessing, A1 HS shows both candidate headings and the specific fact that decides between them, so you know exactly what to confirm before filing.
