Choose this endpoint when you need a fast, single-call lookup of both the standard US duty rate and any Section 301 China tariff surcharge for a specific HTS code, especially for automated cost calculations, trade compliance checks, or product sourcing decisions involving Chinese-origin goods. It is ideal for agents that need structured tariff data without building and maintaining their own HTS/301 database.
