Last updated: August 2026 dataArchitectural millwork—door frames, window casings, moldings, stair components, and engineered wood flooring—serves the residential and commercial construction sectors and is classified under NAICS 321918. Flooring products in this category include solid and engineered hardwood planks, where species, grade, finish, and tongue-and-groove construction distinguish commodity from premium lines. Antidumping and countervailing duty orders on hardwood flooring from China have significantly reshaped sourcing patterns, pushing buyers toward Southeast Asian and European suppliers. Accurate scope determination is essential, as the orders' product coverage turns on construction method and species.

Scope coverage typically turns on construction method (solid versus engineered), species, surface finish, and country of origin. Even flooring assembled in a third country may be subject to circumvention findings if the core components originate from a covered country. Importers should request a formal scope ruling from the Department of Commerce when product specifications are ambiguous.
Millwork components require a commercial invoice specifying species, dimensions, finish type, and end use. If the product contains composite wood panels, EPA TSCA Title VI formaldehyde emission compliance documentation (CARB phase 2 equivalent) may also be required. A licensed customs broker can confirm current entry documentation requirements.
