Tested on rulings it has never seen

Every code below is marked against a binding ruling that US Customs issued between June and August 2026, after the training data was collected.

Why I built it

I've sold wooden curtain poles on Etsy since 2020. Since US de minimis ended, every parcel to the US needs a 10-digit tariff code, and from 9 July Etsy wants sellers outside the US to ship with duties paid. "Handmade gift" doesn't cut it any more.

A general model guesses codes that look right and often don't exist. A small open model, trained on the rulings US Customs publishes, does the boring part properly and costs a fraction of a penny per parcel.

How it works

  1. You describe the item, the way you would in a listing.
  2. Plain code finds the most similar past rulings among about 86,000 that US Customs has published, plus the matching lines of the tariff schedule.
  3. A Qwen3-8B fine-tuned on Tinker reads them and answers with a code, or asks for the one fact it's missing.
  4. Plain code checks the answer against the current US tariff schedule and reads the duty from it. A code that doesn't exist is shown as not real.
