4409.29.06 - Wood continuously shaped along any of its ends, whether or not also continuously shaped along any of its edges or faces, all the foregoing whether or not planed, sanded or end-jointed

This HTS category, 4409.29.06, encompasses nonconiferous wood that has been continuously shaped along any of its ends, edges, or faces. This shaping can include a variety of profiles such as tonguing, grooving, rebating, chamfering, V-jointing, beading, molding, or rounding. The wood may also undergo further processing like planing, sanding, or end-joining. The key characteristic is the continuous shaping that creates interlocking or decorative features along the wood's dimensions, facilitating assembly or enhancing aesthetic appeal.

This specific subheading falls under the broader classification of "Other" nonconiferous wood products that are continuously shaped. It is distinguished from other subcategories within Chapter 44 by its focus on the specific end-use and further processing of shaped, nonconiferous wood not otherwise specified.

Within this category, further subdivisions exist to distinguish specific applications. The subcategory 4409.29.06.55 specifically addresses wood flooring that is end-matched, meaning the ends are shaped to interlock for installation. The residual subcategory, 4409.29.06.65, covers all other types of continuously shaped nonconiferous wood products that do not fall under the end-matched flooring designation.
