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 less 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: Flat Chapter 99 rate replacing the ordinary Column 1 rate. Column 1 General reads “10%”, Column 1 Special reads “10%”, 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.
A replacement rate, not an additional duty — read the column, not the pattern
Most lines in the 9903.82 range read “The duty provided in the applicable subheading + X%”. This one reads simply “10%”, and the difference is substantive: the Chapter 99 rate replaces the ordinary Column 1 rate instead of stacking on it. That is why the heading is limited to articles whose ordinary rate is already under 10 percent — for them, 10 percent is a floor. An entry team that assumes the additive pattern here will over-declare.
Two floors exist, and an article can only stand on one of them
The 10 percent floor here is not the only one in the range. Subdivision (f) sets a 15 percent floor at 9903.82.10 and 9903.82.11, and subdivisions (e) and (k) set a further pair at 9903.82.23 through 9903.82.26 that also reaches articles of copper. An article is provided for in one of those routes, not in whichever produces the friendlier number, so the first question is which subdivision of U.S. note 16 names it — and only after that does it matter where its ordinary rate sits relative to the floor. Column 2 is unchanged on every one of these lines, so none of it reaches an entry taking Column 2 rates.
Headings that displace this one
The article description opens with an “Except as provided for in headings” clause, so 3 headings take precedence over 9903.82.07. 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
Is the 10 percent under 9903.82.07 added to the ordinary duty rate?
No. The Column 1 General and Special entries read “10%” rather than “The duty provided in the applicable subheading + 10%”, so the Chapter 99 rate replaces the ordinary Column 1 rate. Verified against 2026 HTS Revision 15 on August 7, 2026. That is the structural difference from 9903.82.06 and 9903.82.09, which are additive. Column 2 reads “No change”.
What if my derivative article's column 1 rate is exactly 10 percent?
Then 9903.82.08 applies, not 9903.82.07. The pair splits at “less than 10 percent” versus “equal to or greater than 10 percent”, so a rate of exactly 10 percent falls on the 9903.82.08 side and reads “No change” — the ordinary rate already meets the floor. Use the ad valorem equivalent where the ordinary rate is specific or compound.
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.
For the full 9903.82 map in one table, see Section 232 HTS Codes List & 9903.82 Duty Map, which lists every heading in the range with its treatment and cited subdivision. To be told when the range changes, see Section 232 steel and aluminum tariff alerts. For how a Chapter 99 overlay sits on top of the ordinary duty columns, see how U.S. import tariff layers fit together.
