Last updated: July 2026 dataMedium density fiberboard is produced by bonding wood fibers under heat and pressure with resin binders, yielding a smooth, uniform panel widely used in furniture, cabinetry, molding, and retail fixtures. MDF imports are subject to EPA TSCA Title VI formaldehyde emission standards, which require third-party certification from a CARB-approved testing laboratory before the product can be sold in the US. Antidumping and countervailing duty orders have been applied to MDF from certain origins, making supplier-origin verification a critical step in landed-cost calculations for importers.

Under EPA's TSCA Title VI rule, MDF must be certified by a CARB-approved third-party certifier (TPC) confirming compliance with formaldehyde emission limits. Importers must maintain chain-of-custody documentation linking the certified product to the specific mill and production lot; non-compliant panels are subject to recall and civil penalties.
The US has issued antidumping and countervailing duty orders on MDF from specific countries. Before sourcing, importers should check the current scope of active orders with the US Department of Commerce and CBP, request a scope ruling if the product's specifications are borderline, and factor potential duty deposits into landed-cost models — especially when switching to a new supplier country.
