4409.10.10 - Wood siding

HTS 4409.10.10 specifically covers wood siding made from coniferous wood. This category includes lumber that has been continuously shaped along its edges or faces, such as through processes like tongue-and-groove, rebating, chamfering, V-jointing, beading, molding, or rounding. The wood may be planed, sanded, or end-jointed. The primary function of these articles is for exterior cladding or covering of buildings.

This classification is distinct from its siblings, particularly HTS 4409.10.20.00, which is designated for finished wood flooring. While both involve shaped wood, siding is intended for external wall application, whereas flooring is designed for interior floor surfaces. Other related sibling categories like "Wood moldings" and "Wood dowel rods" are differentiated by their specific shapes and primary end-uses, which are not primarily for wall covering.

Within the "Other" subcategory for coniferous wood siding, further distinctions are made. The primary subdivisions are "Resawn bevel siding" and "Other." Resawn bevel siding refers to a specific type of siding characterized by its angled cut and interlocking profile, designed for weather resistance. The "Other" subdivision would encompass any coniferous wood siding that does not fit the specific criteria of resawn bevel siding, but still meets the general requirements of continuously shaped lumber for siding purposes.
