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 8544. 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.

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.
