Import Duty on Aluminum Extrusions
US general (MFN) import duty rates for Aluminum Extrusions range from 1.5%–5% across 7 HTS lines (e.g. HTS 7604.10.10.00 at 5%), per USITC HTS release 2026HTSRev22. This is a planning estimate: Section 301, Section 232, AD/CVD, quotas and MPF/HMF are excluded and must be added separately.
Aluminum extrusions carry Section 232 exposure, and the duty is assessed on the aluminum content rather than on a simple headline rate.

What changes by country of origin
The MFN rate is the same regardless of where the goods are made. Everything below it is not.
| Origin | Base rate | US preference | What else attaches |
|---|---|---|---|
| China | MFN rate above | No US preference on these codes | Section 301 lists 1-4A apply to most consumer goods on top of MFN; the 2026 forced-labor 301 action adds a further layer. |
| Vietnam | MFN rate above | No US preference on these codes | No Section 301 list duty. The 2026 forced-labor 301 action applies. No US FTA, so MFN is the base. |
| India | MFN rate above | No US preference on these codes | No Section 301 list duty and no US FTA. Forced-labor 301 applies. GSP expired, so MFN is the base. |
| Thailand | MFN rate above | No US preference on these codes | No Section 301 list duty and no US FTA. Forced-labor 301 applies. |
| Indonesia | MFN rate above | No US preference on these codes | No Section 301 list duty and no US FTA. Forced-labor 301 applies. |
| Mexico | MFN rate above | No USMCA line on these codes | USMCA: duty-free when the goods meet the rules of origin and the preference is claimed. MFN applies otherwise. |
Free-trade programs named on the lines in this group: Australia (AUSFTA) (7 lines), Bahrain (BHFTA) (7 lines), Chile (CLFTA) (7 lines), Colombia (CTPA) (7 lines), Agoa (7 lines), Caribbean Basin (7 lines). A preference only applies when the goods meet that program's rules of origin and the claim is made on entry. This page does not estimate Section 301 list rates or anti-dumping duty; enter the applicable Section 301 rate in the calculator yourself and verify current list coverage and exclusions at the USTR exclusion notices.
What decides the rate
7604 covers aluminum bars, rods and profiles. Aluminum products have been subject to Section 232 measures at rates well above the MFN line, and the assessment can depend on the aluminum content of the article. Extrusions from several origins have also faced anti-dumping orders, which this site does not estimate.
Where this goes wrong
An extrusion machined into a finished part may leave 7604 for a machinery heading. Fabrication beyond simple cutting changes the classification, so the scope of the US processing matters.

Questions this page answers
What applies to aluminum extrusions beyond the 1.5% to 5% MFN rate?
Section 232 measures on aluminum sit well above the MFN line, and assessment can depend on the aluminum content of the article. Extrusions from several origins have also faced anti-dumping orders, which this site does not estimate.
Does machining an extrusion change its classification?
Fabrication beyond simple cutting can move it out of 7604 into a machinery heading. The scope of the processing matters, so the routing steps should be documented.
Does this estimate include anti-dumping duty?
No. Anti-dumping and countervailing duty are case-specific and can exceed every other layer combined, so they are outside the estimate by design. The calculator covers base duty, the Section 301 and 232 layers you enter, the merchandise processing fee and the harbor maintenance fee.
