About
A serious tool for serious importers
TariffClassify is built for trade-compliance professionals, importers, and customs brokers who need defensible HTS classifications and accurate landed-cost figures. Everything we do starts from the General Rules of Interpretation and the live HTSUS schedule — not from a black box.
What we do
We classify products under the correct 10-digit US HTS code by applying the General Rules of Interpretation systematically — the same framework used by licensed customs brokers and CBP itself. Every classification cites the GRIs applied, the alternative codes considered, and the reasoning that selected the winning code. Confidence scores and alternative codes are surfaced for human review on every result.
On top of the base classification, we layer the duty-rate overlays that change what importers actually pay — Section 301, IEEPA, AD/CVD, and Section 232. The free landed-cost calculator computes total delivered cost including the Merchandise Processing Fee and Harbor Maintenance Fee, with USMCA exemptions flagged automatically.
GRI-driven reasoning
Every classification cites the General Rules of Interpretation applied. No black-box answers, no unexplained codes.
2026 HTSUS — 35,571 provisions
Indexed against the current USITC schedule. Re-indexed when USITC publishes revisions.
Section 301, IEEPA, AD/CVD overlays
Every classification checks for additional duty layers automatically. The total duty stack is on the result, not buried in your broker's invoice.
Defensible, not magical
Reasoning, alternative codes, and confidence scores on every classification — for the moment a CBP officer asks you to defend it.
Where our data comes from
- 2026 HTSUS schedule — published by the US International Trade Commission (USITC). We index the full machine-readable JSON release covering all 35,571 tariff provisions and re-index when USITC publishes revisions.
- Section 301 lists — sourced from the US Trade Representative's Section 301 docket. We track Lists 1–4A and document active product-specific exclusions.
- AD/CVD orders — from the International Trade Administration's ACCESS docket and Commerce Federal Register notices.
- Import statistics — from the US Census Bureau Foreign Trade API, with caching to respect rate limits.
- Binding ruling history — referenced from CBP's CROSS database where directly applicable.
What we are not
TariffClassify is not a substitute for a licensed customs broker, a customs attorney, or a binding ruling from CBP. AI-assisted classification is research support, not legal advice. For commercial entries — especially large or high-stakes ones — verify codes with a qualified professional and consider filing a binding ruling on borderline cases.
