Every heading in the 9903.82 range as read from the live USITC export for 2026 HTS Revision 15 on 2026-08-07. Heading numbers link to the page for that heading, which carries the verbatim article description and the cited U.S. note 16 subdivision.
This index maps Chapter 99 treatments, not ordinary product classifications. Confirm the Chapter 1–97 HTS code and the relevant subdivision of U.S. note 16 first, then metal weight, origin, ordinary Column 1 rate, and entry date.
Three things this range gets used for, and one it cannot settle
The 9903.82 headings answer three operational questions. Which line does a covered metal article report on — the residual plus-50-percent line at 9903.82.02, or one of the narrower origin, threshold, or carve-out lines that displace it? What does the line actually do to the duty: 5 of the 26 headings replace the ordinary Column 1 rate with a flat Chapter 99 rate rather than adding to it, and two put the duty in the Special subcolumn where a Column 1 comparison cannot see it. And which subdivision of U.S. note 16 has to be read before the line can be claimed.
What the range cannot settle is the ordinary classification. A Chapter 99 heading is reported alongside a Chapter 1–97 code, so the base subheading, the metal content, the country of origin, the ordinary Column 1 rate, and the entry date all have to be resolved first. Several lines here also carry an “Except as provided for in headings” clause that reaches outside the 9903.82range entirely — 9903.85.67 and 9903.85.68, the Russian aluminum provisions at the applicable subheading’s duty plus 200 percent — so a review scoped to this subchapter alone can miss the most expensive outcome available.
Which coverage this index claims, and which it does not
26 headings have their own page here because 26 headings were read directly against the live schedule. The count is measured rather than assumed: an export request spanning 9903.82.01 to 9903.82.99 returned exactly 26 rows on Aug 7, 2026, ending at 9903.82.26. The other Chapter 99 families this site cites — the 9903.05 country-action headings behind the 2026 Brazil and forced-labour actions, and the 9903.88 Section 301 list and exclusion headings — appear in reference tables and change notices with their official sources, but have no per-heading pages, because publishing one per mention would mean publishing pages nobody had checked against the schedule.
Frequently asked questions
What is a Chapter 99 heading?
A Chapter 99 heading is a temporary provision reported alongside an ordinary Chapter 1–97 HTS classification, never instead of it. It carries the trade-remedy or program treatment — an additional duty, a replacement rate, or an explicit no-change carve-out — while the ordinary subheading still supplies the base rate, the units, and the classification itself. The 9903.82 range holds the Section 232 aluminum, steel, and copper provisions.
How many Section 232 headings are in the 9903.82 range?
26, from 9903.82.01 through 9903.82.26, as read from the live USITC export on Aug 7, 2026. That is a measured count rather than an assumption: an export request spanning 9903.82.01 to 9903.82.99 returned exactly 26 rows, ending at 9903.82.26. USITC published four revisions in fourteen days during 2026, so re-run the export against the current release before treating the count as fixed.
Why do two Chapter 99 headings sometimes have the same article description?
Because the distinguishing conditions live in the U.S. note the heading points to, not in the heading text. 9903.82.20 and 9903.82.21 both read “Derivative steel articles as provided in subdivision (j) of U.S. note 16 to this subchapter” in the live export, yet one adds 25 percent and the other reads “No change”. 9903.82.15 and 9903.82.16 are a second identical-description pair, fifteen points apart. Any mapping built from descriptions alone will get one of each pair wrong.
Does a stated percentage in this range always mean an additional duty?
No, and the distinction changes the amount owed. A column reading “The duty provided in the applicable subheading + 25%” adds to the ordinary rate. A column reading simply “15%” replaces the ordinary Column 1 rate, which is how the threshold pairs at 9903.82.07/.08, .10/.11, .23/.24 and .25/.26 implement a minimum effective rate rather than a surcharge. Read the column text, not the pattern.
Are all 9903 headings covered here?
No. Tariff Sentinel publishes a page per heading only for the 9903.82 Section 232 range, because those 26 headings were read line by line against the live schedule. The 9903.05 country-action headings and the 9903.88 Section 301 list and exclusion headings appear in this site's reference tables and change notices, cited to the official source, but do not have their own pages yet.
