Do Section 301, 232 or 201 tariffs apply to HTS 0304?

It depends on the 8- or 10-digit subheading, the country of origin, the entry date and, for Section 232, the metal content. These additional duties are listed in Chapter 99 of the HTS. The free duty calculator checks each program for a given code, origin and date and shows which apply and why.
