Know before you ship.
Flags when a code falls under an antidumping or countervailing order, a SIMA finding, a tariff-rate quota, or a partner-agency requirement such as food, plant or product safety declarations. One screen, both countries.
A classification you can defend.
Describe the product and TariffSense works through the questions that decide the heading: material, function, assembly, use. It researches rulings and tariff notes, lays out the branches ("if it is X, then heading A; if Y, then B") and produces a written report you can keep in the file. Structured questionnaires are available for teams that prefer a guided path.
Search by number or by description.
Browse the tariff, search descriptions in plain language, and read the chapter and section notes that matter for the heading you are looking at.
Duty data where your systems and agents can use it.
Pull rates, measures and screening results into your ERP, your TMS or your own AI assistant through our API and MCP server.
