USITC finds injury in Chinese fiberglass door panels case — AD/CVD orders are next

Updated July 11, 2026 · Impact score 83/100 · Confidence 93%

The USITC determined on July 9, 2026 that a U.S. industry is materially injured by dumped and subsidized fiberglass door panel imports from China, clearing the final statutory step before Commerce issues antidumping and countervailing duty orders.

Why it matters

Importers of Chinese fiberglass door panels should treat the June 15 final Commerce rates as moving into order stage. Covered door slabs, sidelites, and unfinished panels under HTS 3925.20.0010 and related codes are now positioned for binding AD/CVD order treatment once Commerce publishes the orders.

What to check next

Identify open purchase orders and in-transit shipments under HTS 3925.20.0010 and related codes, confirm exporter-specific AD/CVD rates with your broker, and watch for Commerce's order publication before finalizing landed-cost assumptions.
