Last updated: August 2026 dataResidual wood joinery and carpentry for construction — spanning drilled or notched studs (4418991000), laminated wood arches (4418999110), roof trusses (4418999120), fabricated structural members (4418999140), prefabricated partitions and panels (4418999150), and wood flooring (4418999105) — feeds directly into residential and commercial building supply chains. Canada is the primary supplier, with Brazil, Vietnam, Cambodia, and Chile also among the leading sources. The breadth of product forms within this heading means that classification at the 10-digit level requires careful matching of the specific product geometry and function to the correct tariff line, as duty rates and trade-remedy exposure can differ across lines.

Prefabricated wood partitions and panels classified at 4418999150 are building components — individual panels or partition elements intended for assembly on-site. Complete prefabricated building sections or modular units that constitute a substantial portion of a structure may instead fall under Chapter 94 (prefabricated buildings). The distinction turns on whether the goods are components for incorporation into a building versus a substantially complete structural unit; a binding ruling from CBP is advisable for modular or panelized systems near this boundary.
Canada offers proximity and USMCA-based trade terms, making it a reliable baseline source for structural wood members. Brazil and Vietnam supply a wider range of tropical and processed wood joinery, but both origins require attention to chain-of-custody documentation under the Lacey Act, which prohibits importation of wood products harvested in violation of source-country laws. Diversifying across these origins can reduce concentration risk but increases the compliance documentation burden.
