Tariff Intelligence
Drop in a spec sheet and get back the HTS code, every tariff layer and the landed $/lb, with each rate checked against official sources and the risky ones flagged.
Version 14
Example: sodium sesquicarbonate from China
| Layer | Rate |
|---|---|
| HTS 2836.99.50.50 (Other carbonates) | 3.7% |
| Section 301, List 3 | +25% |
| Section 301, forced labor | Exempt (9903.05.86) |
| Section 232 and AD/CVD | None |
| Total duty | 28.7% (29.17% with fees) |
Flagged risk. CBP has never ruled on this product. If it were classed as soda ash (2836.20) instead, it would lose the forced-labor exemption and the duty would jump to 38.7%. The recommendation: confirm with the broker or request a binding ruling.
Example output from the tool. Tariff rates change, so check current sources before relying on any figure here.
What it does
- Send it a spec sheet, a COA or just a product name and an origin, and it works out the 10-digit HTS code.
- Builds the full US duty stack layer by layer: base rate (MFN), Section 301 China lists and exclusions, Section 301 forced labor with the exemptions that apply to the end use, Section 232, duty suspensions (9902) with expired ones flagged, antidumping and countervailing duties, and processing and harbor fees.
- Converts the result to landed $/lb.
- Research agents check every rate against primary sources: the live HTSUS, USTR lists, CBP rulings and the Federal Register. Anything that cannot be confirmed is flagged instead of guessed.
- Runs on Claude, using several agents and purpose-built skills made from official USTR and other government sources.
A working tool, not customs advice.
