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.

Trade-agreement preferences
Lines in this heading print a preferential rate for goods that qualify under these programs. The special column above shows which program codes each line carries. Qualification is a fact about the goods (rules of origin, certification on file), not about the country they shipped from.

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:
- Section 232Section 232 metals note 16(c)(ix)/(x) equipment-class ladder (headings 9903.82.07/.08/.10/.11/.12, for classes like 8457/8428/8432/8415.10.60): a good here is a Section 232 derivative when at least 15% of its weight is the covered metal (steel or aluminum). If so, apply heading 9903.82.10 with the 'Section 232 derivative' claim (the additional duty tops the column-1 rate up to 15% total), which from 2026-07-24 also removes the forced-labor 301 duty under 9903.05.90 (note 52(f)). Origin-specific headings (9903.82.12 for GN 3(b) countries, 9903.82.17 for Russia) and capped ag/industrial-use headings (9903.82.23 to .26, including a 10% tier that needs at least 85% U.S. melt) are not computed and may apply instead. Verify melt-and-pour, metal content and end use. Goods actually under this §232 regime are likewise exempt from the Brazil 301 25% (9903.05.07, BR origin, from 2026-07-22) and the Canada §338 50% (9903.03.15, CA origin, from 2026-08-19): any such line shown for them overstates; verify.

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.
