On June 15, 2026, the Supreme Court of the United States denied a petition for certiorari in HTMX Industries, LLC, et al., the lead case challenging the imposition of additional duties on merchandise imported from China pursuant to Section 301 Lists 3 and 4A. The U.S. Court of International Trade (CIT) and the U.S. Court of Appeals for the Federal Circuit had previously approved the Section 301 duty assessments under List 3 and List 4A.
The Supreme Court’s decision not to hear the case, which was announced by the Court with no explanation, marks the end of the litigation that began in 2020, and which grew to include over 6,000 importers. We anticipate that the CIT will establish procedures to dismiss the cases that had been stayed pending resolution of the lead case.
