US tariff tools

Hand-curated workflows for HTS classification, China HS bridging, and US import duty decisions. Every figure traces back to USITC Harmonized Tariff Schedule and US Federal Register source records.

These tools are built for cross-border sellers, small importers, and customs brokers who need to reason about US import duty on a specific shipment without paying for an enterprise classification system. Use them alongside the calculator on the home page, or save SKUs to track Section 301, IEEPA, and Reciprocal tariff changes over time.

Last updated April 2026 · USITC HTS sync weekly · Federal Register sync every 6 hours.

China HS to US HTS candidate finder Start with a China tariff code (HS8 / HS10 / 章则) or a Chinese product name. The tool resolves the shared HS6 anchor and surfaces every US HTS line that begins with the same six digits, ranked by likelihood. Built for sellers shipping from China who already know their domestic classification but need to cross-walk to USITC for landed cost.

On the roadmap

  • AD/CVD lookup Planned

    Check whether an HTS line is currently subject to anti-dumping or countervailing duties, with the underlying Commerce case number.

  • De minimis status checker Planned

    Decide whether a shipment qualifies for the $800 de minimis exemption after the 2025 China rule changes.

  • Origin shift calculator Planned

    Estimate landed-cost delta when sourcing the same SKU from a different country, factoring Section 301 and FTA preferences.

  • Export rebate lookup Planned

    Pull the China export VAT rebate rate for a given HS line so margin math accounts for the upstream credit.
