All-in 2026 rate by country of origin

The general rate plus every additional duty the engine applies for that origin on September 2, 2026(Section 301, Section 232, Section 201, Section 338, and the forced-labor Section 301 action), as a share of customs value. Columns appear only for origins that carry an additional layer somewhere in this heading; for every other origin the all-in rate is the general rate.

A range means the 10-digit lines under that 8-digit line resolve differently. "+" marks a line with a per-unit duty component the percentage does not capture. "*" marks lines the engine could not price. Chapter 99 headings beneath a rate are the additional-duty provisions applied. AD/CVD, quota, and the regimes listed under "Not included" are not in these numbers.

Not included in the numbers above

Antidumping and countervailing duties, tariff-rate quotas, and partner-agency requirements are never in these rates. The engine also flags regimes it knows about but does not compute for this heading:

No unmodeled regime in the current measures bundle touches heading 8481. That is not a statement that no AD/CVD order exists for these goods: check the Commerce Department's orders for the specific product and origin before relying on a landed cost.

Questions about HTS 8481

What is the U.S. import duty rate for HTS 8481?

The general (column 1) rate for the 14 rate lines under heading 8481 is Free to 5.6%. That is the base rate for goods from countries with normal trade relations. Additional duties stack on top by origin: for goods from China entered on September 2, 2026 the all-in ad valorem rate is 23% to 50%.

Is HTS 8481 subject to Section 301 tariffs on goods from China?

Yes. Section 301 List 1 (9903.88.01), Section 301 List 3 (9903.88.03), Section 301 List 4A (9903.88.15) applies to goods of Chinese origin under this heading, on top of the general rate.

How many HTS codes are in heading 8481?

Heading 8481 has 14 legal rate lines (8-digit) and 61 filable statistical lines (10-digit) in the 2026 HTS Revision 17. The entry is filed at the 10-digit level; the rate is set at the 8-digit line.

Which trade agreements give a lower rate under HTS 8481?

Lines in this heading list preferential rates for goods that qualify under U.S.-Australia FTA, Automotive Products Trade Act (Canada), U.S.-Bahrain FTA, U.S.-Chile FTA, U.S.-Colombia TPA, CBERA, U.S.-Israel FTA, U.S.-Jordan FTA, KORUS (U.S.-Korea FTA), U.S.-Morocco FTA, U.S.-Oman FTA, CAFTA-DR, U.S.-Panama TPA, U.S.-Peru TPA, USMCA, U.S.-Singapore FTA, U.S.-Japan Trade Agreement. The special column shows the program codes per line. Eligibility depends on the rules of origin and the certification on file, not on the shipping country alone.

How this page is built

The rate lines are the USITC 2026 HTS Revision 17 export, unedited. The all-in rates come from the Borderless tariff engine (the same code behind the tariff simulator), run for each 8-digit line and origin with an entry date of 2026-09-02; its measures bundle is dated 2026-08-21and cites the Federal Register and CBP notices behind every layer. Page generated 2026-09-02. These are estimates for planning, not classification advice or a filing: the classification of your goods, the origin determination, and any claim are confirmed by a licensed broker before an entry is filed. Maintained by Borderless CHB; Joy Xue, Licensed U.S. customs broker (CBP filer code NQR), confirms the classification and the duty stack on every entry before it is filed.
