The forced-labor tariff may not apply. The legal text: “articles that are civil aircraft (all aircraft other than military aircraft); their engines, parts and components; their other parts, components and subassemblies; and ground flight simulators and their parts and components, that otherwise meet the criteria of general note 6 of the HTSUS” (HTS 9903.05.88).

The auto and auto-parts tariff doesn't apply to “all entries of articles classifiable under provisions of the HTSUS enumerated in subdivision (g) of this note or meeting the requirements of subdivision (p) of this note … (ii) that are not parts of passenger vehicles (sedans, sport utility vehicles, crossover utility vehicles, minivans, and cargo vans) and light trucks” (HTS 9903.94.06).

No forced-labor tariff on line 4009.12.0020: the auto and auto-parts tariff (HTS 9903.94.05) or the truck and bus tariff (HTS 9903.74.08) covers it instead, whichever applies.

Depending on the goods, the auto and auto-parts tariff (HTS 9903.94.05) or the truck and bus tariff (HTS 9903.74.08) applies, never both; the stack shows the auto and auto-parts tariff.

Court status: Challenged at the U.S. Court of International Trade in In re Section 301 Forced Labor Cases, Court No. 26-03555-3JP, before a three-judge panel. The plaintiffs, Learning Resources and others, have moved for judgment on the agency record, arguing that the action (91 FR 47318) exceeds USTR's statutory authority, is arbitrary and capricious, and is pretextual; 25 states, plaintiffs in Court No. 26-cv-03467-3JP, support them as amici (brief filed Sep 11, 2026). No ruling as of Oct 1, 2026, so the rate is unchanged.
