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.
