The Department of Commerce initiated sunset reviews effective April 1, 2026 for eleven antidumping duty orders and four countervailing duty orders, triggering a five-year evaluation period that could result in order continuation or revocation. Trade compliance systems that cache duty rates tied to these specific case numbers must flag these orders for potential rate changes.

The AD proceedings span mattresses from six countries: Cambodia (A-555-001), Malaysia (A-557-818), Serbia (A-801-002), Thailand (A-549-841), Türkiye (A-489-841), and Vietnam (A-552-827). All six mattress cases are first reviews, indicating these orders were originally imposed approximately five years ago and are now subject to their initial sunset evaluation under section 751(c) of the Tariff Act of 1930.

Chinese Industrial Products Under Review: Six distinct product categories from China face AD sunset reviews: Boltless Steel Shelving Units Prepackaged for Sale (A-570-018, 2nd Review), Chassis and Subassemblies (A-570-135, 1st Review), Non-Refillable Steel Cylinders (A-570-126, 1st Review), Prestressed Concrete Steel Wire Strand (A-570-945, 3rd Review), and Small Vertical Shaft Engines (A-570-124, 1st Review).

The CVD proceedings add four more case numbers to track: C-570-019 for Chinese boltless steel shelving (2nd review), C-570-136 for Chinese chassis and subassemblies (1st review), C-570-128 for Chinese mattresses (1st review), and C-570-127. Systems querying HTS subheadings associated with these products should implement monitoring for these Commerce case numbers.

Data Integrity Alert: The procedures governing these reviews fall under 19 CFR 351.218(c). Compliance engineering teams should note that revocation of any order would eliminate the corresponding AD/CVD duty rates from applicable HTS classifications. Continuation would maintain existing rates but may include margin recalculations.

The U.S. International Trade Commission is publishing concurrent Institution of Five-Year Reviews notices with corresponding ITC case numbers (731-TA series for AD, 701-TA series for CVD). For the chassis and subassemblies order alone, the ITC case number is 731-TA-1537 for AD and 701-TA-657 for CVD—both numbers that downstream compliance systems may need to cross-reference.

The prestressed concrete steel wire strand order (A-570-945) entering its third review represents the longest-standing order in this batch, having survived two prior sunset evaluations. The boltless steel shelving orders (A-570-018 and C-570-019) are entering their second reviews. All other orders are first reviews, reflecting the wave of trade actions implemented around 2020-2021.

Commerce contacts for specific cases include Walter Ankner at (202) 482-8374 for all mattress proceedings, Thomas Martin at (202) 482-3938 for boltless steel shelving and prestressed concrete steel wire strand, and Mary Kolberg at (202) 482-1785 for chassis, non-refillable steel cylinders, and small vertical shaft engines.
