Tariff Monitor: US Import Tariff Lookup

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.
