Frequently asked questions

What is the duty rate for HTS 2922?

Heading 2922 has 64 rate lines. The general (MFN) duty rates are 6.5% (38 lines), Free (15 lines), 5.8% (6 lines), 3.7% (3 lines). Products of free trade agreement partners may enter at the special rate, and Column 2 rates apply to countries without normal trade relations. Chapter 99 tariffs can be added on top: calculate the full amount.

Do Section 301, 232 or 201 tariffs apply to HTS 2922?

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.

What fees are added to an import under HTS 2922?

Formal entries pay the Merchandise Processing Fee of 0.3464% of value (minimum $34.58, maximum $670.86 in FY2027). Ocean shipments also pay the Harbor Maintenance Fee of 0.125% of value. See the import duty calculator for how they combine.
