Look up US import duty rates and HTS codes from the official US Harmonized Tariff Schedule (USITC). Ask "what is the tariff on LED lamps from China" or "HTS code for wooden toys": Dutyfinch finds matching codes, shows the general, special and column 2 rates, and flags whether Section 301 China duties apply (lists 1-4B, exclusions and the 2024 increases), with the official source link. General information only, not customs or legal advice.
Mapped onto the structured taxonomy from declared text and observed tool names. Confidence shown for derived entries.
