4421.99.10.00 - Coniferous

HTS 4421.99.10.00 specifically covers coniferous wood dowel pins that are plain, meaning they do not have any additional shaping, threading, or finishing beyond basic preparation for use as dowels. These are essentially cylindrical rods of coniferous wood intended for use as fasteners, joinery components, or support elements in furniture, cabinetry, construction, and other applications where the joining of two or more pieces of wood is required.

This classification distinguishes itself from its sibling category, 4421.99.15.00 ("Other"), by its specific focus on plain coniferous dowel pins. While the "Other" category would encompass a broader range of wooden articles not specifically classified elsewhere within the 4421.99.10 subheadings, this subheading is narrowly defined for the simple dowel pin form factor made from coniferous woods.

As a leaf node in the HTS structure, 4421.99.10.00 does not have further subcategories. Therefore, the classification relies on the precise identification of the article as a plain dowel pin manufactured from coniferous wood. Key classification criteria would include the cylindrical shape, the material being coniferous timber, and the absence of specialized features such as pre-drilled holes, screw threads, or decorative finishes that would necessitate classification under a different, more specific subheading.
