Overview
Calculates import duty what-if scenarios: current vs proposed duty and landed-cost deltas from caller-supplied values, rates, freight, insurance, quantity, origin, destination, and optional HTS code. Scenario math only: does not choose final HTS classification, act as customs broker, or file customs documents. Use it as a tariff duty scenario calculator, landed cost delta API, or HTS cost scenario tool.
