4421.99.20.00 - Sanded, grooved or otherwise advanced in condition

This HTS category, 4421.99.20.00, specifically covers wood dowel pins that have undergone further processing beyond basic shaping. This includes dowel pins that have been sanded to a smooth finish, grooved for improved grip or adhesion, or otherwise modified to enhance their utility or appearance. The key differentiator here is the advanced condition of the wood dowel pins, indicating that they are ready for direct use in applications such as furniture assembly, construction, or crafting without requiring significant additional preparation by the end-user.

Within the broader classification of "Other articles of wood," and specifically under "Other" subcategories leading to "Other," this leaf node distinguishes itself from plain, unfinished wood dowel pins by the evident finishing or modification processes applied. While plain dowel pins would fall into a sibling category, this classification captures those where labor or manufacturing processes have already been incorporated, making them a distinct product.

As a leaf node, there are no further subcategories under HTS 4421.99.20.00. Therefore, the focus for classification purposes rests on the presence of the specified advancements: sanding, grooving, or any other comparable processing that alters the dowel pin from its raw or basic form. This ensures that only appropriately finished wood dowel pins are classified here, aligning with the principle of capturing goods at their most specific level of detail within the tariff schedule.
