Millwork intended for interior use in the US should typically be kiln-dried to a moisture content of 6–9% to minimize warping, shrinkage, or joint failure after installation. Shipments arriving at higher moisture levels may be rejected by buyers or require costly re-drying. Importers should specify moisture content in purchase contracts and request mill certificates confirming kiln-drying treatment.

The scope of antidumping orders on wooden moldings and millwork is defined by the US Department of Commerce order and any subsequent scope rulings. Importers should review the order's product description carefully — covering factors such as species, profile type, and surface finish — and may request a formal scope ruling from Commerce if their product's coverage is uncertain.
