Exporters and importers of these panels must now account for additional duty liabilities on all Chinese sourced fiberglass door panels entering US ports.

On June 15, 2026, the U.S. Department of Commerce announced a final affirmative countervailing duty (CVD) determination against fiberglass door panels exported from China. The investigation, which covered the period January 1, 2024, through December 31, 2024, concluded that countervailable subsidies are being provided to Chinese producers and exporters of these panels.
Who Is Affected
This determination applies to all fiberglass door panels (HS Chapter 70 products, though not explicitly stated in the source) originating in China and imported into the United States. Importers, distributors, and retailers sourcing these panels from Chinese manufacturers will face additional duty assessments retroactively applied to entries during the investigation period and prospectively on future shipments.
The U.S. Department of Commerce determines that countervailable subsidies are being provided to producers and exporters of fiberglass door panels from the People's Republic of China.
Exporters and customs brokers must recalculate landed costs for affected shipments, adjust pricing strategies, and determine whether to absorb CVD costs or pass them to US customers.
What This Means for Shippers
All importers with fiberglass door panels from China must immediately revise their cost estimates to include the new countervailing duties. Review prior-period entries during January–December 2024 for potential additional duty liability and prepare for increased landed costs on all future China-sourced door panel shipments. Engage your customs broker or logistics partner now to quantify the CVD impact and adjust supplier negotiations accordingly.
