Last updated: August 2026 dataStructural wood posts and beams classified here are those not falling under the engineered wood subheadings 4418.81–4418.89 (glulam, CLT, etc.), making species, dimension, and processing method the key classification determinants. Canada dominates supply, consistent with its role as the primary source of dimensional softwood lumber for US construction markets. Slovenia and Sweden also appear among leading suppliers, reflecting European glued or finger-jointed solid timber exports. The single US tariff line under this heading is 4418300100.

Heading 441830 covers solid or finger-jointed sawn timber posts and beams that are not engineered through lamination processes. Glue-laminated timber (glulam, 441881) and cross-laminated timber (CLT, 441882) are specifically excluded and classified in their own subheadings. The key test is whether the structural member is a single sawn piece (or finger-jointed solid) versus a composite of glued laminations.
Softwood lumber from Canada has historically been subject to antidumping and countervailing duty orders. Whether a specific post or beam shipment falls within the scope of those orders depends on the product's species, dimensions, and end-use, as defined in the relevant Commerce Department scope rulings. Importers should verify current scope and deposit rates with a licensed customs broker before entry.
