Tariff Monitor: US Import Tariff Lookup
Claude connectorCommunityLook up US HTS codes and estimate stacked import tariff rates (MFN, Section 301, Section 232) by origin country.
Tariff Monitor answers US import tariff questions from the USITC Harmonized Tariff Schedule (19,856 10-digit codes).
Tools:
- lookup_hts_code: finds HTS codes for a product name or numeric prefix. Common product words (laptop, earbuds, e-bike) are mapped to the official heading that covers them.
- calculate_tariff: estimated total rate for one HTS code and origin country, broken into layers: MFN base rate, Section 301 China (matched by HTS line, Lists 1 to 4A), Section 232, and the 2026 Section 301 forced-labor tariff. Each answer gives the date the data was checked, the exemptions and assumptions applied, and optionally the annual dollar duty for a given import value.
- compare_origins: one HTS code across 2 to 8 origin countries, lowest rate first.
All three tools are read-only. Figures are estimates for planning, not customs rulings; confirm at hts.usitc.gov. Preferential rates (USMCA, free trade agreements) are not applied. No account or API key. Limit: 25 tool calls per IP address per day.
