4403.12.00 - Nonconiferous

This HTS category, 4403.12.00, encompasses nonconiferous wood in its rough state, regardless of whether the bark or sapwood has been removed or if it has been roughly squared. This classification specifically pertains to wood that has been treated with preservatives such as paint, stain, or creosote. The treatment is applied to protect the wood from decay, insects, or other environmental damage, extending its usable life for various applications.

Crucially, this category is distinguished from its sibling, 4403.11.00, by the botanical origin of the wood. While 4403.11.00 covers treated coniferous woods (like pine, spruce, or fir), 4403.12.00 is exclusively for treated wood derived from nonconiferous trees (such as oak, maple, or mahogany). The "nonconiferous" characteristic is the primary determinant for classification within this particular sub-heading.

The subcategories under 4403.12.00 provide further refinement based on the intended end-use of the treated nonconiferous wood. Specifically, "Poles, piles and posts" address wood cut to form these structural elements, often for construction or infrastructure purposes. The remaining "Other" subcategory serves as a residual classification for treated nonconiferous wood that does not fall into the specific uses of poles, piles, or posts, but still meets the criteria of being in rough form and having received preservative treatment.
