The U.S. International Trade Commission instituted five-year sunset reviews on April 1, 2026, for antidumping and countervailing duty orders on chassis and subassemblies from China under Investigation Nos. 701-TA-657 (CVD) and 731-TA-1537 (AD). Interested parties must submit responses by May 1, 2026, with adequacy comments due June 9, 2026.

The original countervailing duty order was issued May 10, 2021 (86 FR 24844), followed by the antidumping duty order on July 8, 2021 (86 FR 36093). These orders have now reached their five-year statutory review period under 19 U.S.C. 1675(c), which requires the Commission to determine whether revocation would likely lead to continuation or recurrence of material injury to the domestic industry.

Key Dates for Compliance Teams:
• Review instituted: April 1, 2026
• Response deadline: May 1, 2026
• Adequacy comments deadline: June 9, 2026
• Contact: Peter Stebbins, Office of Investigations (202-205-2039)

The subject merchandise scope covers chassis and subassemblies from China. In the original determinations, the Commission defined the Domestic Like Product as coextensive with the investigation scope—all domestically produced chassis and subassemblies thereof. The Domestic Industry definition includes all domestic producers except CIMC Intermodal Equipment, LLC's assembly operations, which were excluded.

Importer Action Required: The Commission will assess response adequacy to determine whether to conduct full or expedited reviews. Expedited review determinations rely on facts available, potentially including only information submitted in response to this notice. Importers of subject merchandise should track this proceeding via EDIS at edis.usitc.gov.

For trade compliance engineering teams, the outcome of these sunset reviews directly impacts duty rate calculations on HTS classifications covering chassis imports from China. If the orders are revoked, AD/CVD rates would drop to zero for subject merchandise. If continued, current duty margins remain in effect for another five years. Systems pulling live tariff data must be prepared to update cached AD/CVD rates based on the Commission's final determination, expected later in 2026.
