Official article description
Except as provided for in headings 9903.82.12, 9903.82.17 and 9903.85.68, derivative aluminum and steel articles with an ad valorem (or ad valorem equivalent) rate of duty under column 1 equal to or greater than 10 percent, as provided for in subdivisions (c)(ix)–(x) and (e) of U.S. note 16 to this subchapter
Transcribed verbatim from the live USITC export for 2026 HTS Revision 15 on Aug 7, 2026. The heading text points to U.S. note 16(c)(ix)–(x) and (e); the enumerated scope lives in that note, not in the description above.
How this heading is treated
- Treatment: No change to the ordinary subheading rate. Column 1 General reads “No change”, Column 1 Special reads “No change”, and Column 2 reads “No change”.
- Metals reached: Derivative aluminum and steel articles.
- Origin condition: Any origin except general note 3(b) countries and Russian-origin derivative steel.
- Controlling note: U.S. note 16(c)(ix)–(x) and (e), in the legal notes to subchapter III of Chapter 99.
“No change” here is the output of a calculation, not an exemption
It is easy to read this heading as a carve-out, but it is the upper half of a minimum-rate mechanism. 9903.82.07 replaces the ordinary Column 1 rate with a flat 10 percent for derivative aluminum and steel articles whose rate is below that level; 9903.82.08 takes the same articles when the rate is at or above 10 percent and leaves it alone. Reporting under this heading is therefore a positive claim that the ad valorem or ad valorem equivalent rate clears the threshold, and the arithmetic behind it is the importer's record.
A heading that can change without the product changing
Nothing about the article decides this heading on its own. What decides it is whether the ordinary Column 1 rate for the subheading clears 10 percent, so an amendment to that ordinary rate, a reclassification, or — where the ordinary rate is specific — a movement in entered unit value can move the same part from 9903.82.08 to 9903.82.07 with no change at all in the goods. That is an argument for re-checking the heading against HTS revisions and against price movement, rather than storing it in a product master as a settled attribute.
Headings that displace this one
The article description opens with an “Except as provided for in headings” clause, so 3 headings take precedence over 9903.82.08. Rule them out before applying the treatment above.
9903.82.12— General note 3(b) origins — plus 25%9903.82.17— Russian derivative steel — plus 25%9903.85.68— outside the 9903.82 range; read it in the official USITC lookup
Tariff Sentinel publishes a page per heading only for the 26 9903.82 headings read directly against 2026 HTS Revision 15. The heading 9903.85.68 above sits outside that range, so it is cited to the official lookup rather than summarised here.
Frequently asked questions
Does 9903.82.08 mean no Section 232 duty applies?
It means no additional duty is added, because the ordinary Column 1 rate already equals or exceeds the 10 percent floor that 9903.82.07 imposes on the same articles. All three columns read “No change” in 2026 HTS Revision 15, read August 7, 2026. It is not an exemption: the article is still covered by U.S. note 16, and reporting the heading claims that the threshold test is met.
Can the same part report 9903.82.08 on one entry and 9903.82.07 on another?
Yes. The heading turns on whether the ordinary Column 1 rate clears 10 percent, not on a property of the goods. Where that ordinary rate is specific or compound, its ad valorem equivalent moves with entered unit value, so a lower-priced entry of the same part can fall below the threshold and go to 9903.82.07 at a flat 10 percent instead. A tariff revision that changes the ordinary rate produces the same shift with no pricing change at all.
How to use this page
A Chapter 99 heading is reported alongside an ordinary Chapter 1–97 classification, never instead of it, so this page is the second half of a two-part answer. Settle the ordinary classification and the country of origin first, then read U.S. note 16(c)(ix)–(x) and (e) against the article, then select the heading. Where a rate threshold is involved, the test runs on the ad valorem equivalent for that entry, which makes it value-dependent rather than a fixed attribute of the part.
