7616.10.90.30 - Threaded fasteners

This category, HTS 7616.10.90.30, specifically classifies threaded fasteners made of aluminum. This includes a broad range of items designed for joining or fastening materials through the use of screw threads. Examples within this classification encompass aluminum screws, bolts, nuts, washers, rivets, and similar components. The defining characteristic is their threaded nature and their composition of aluminum.

Within the broader heading for aluminum articles, and more specifically for fasteners, this subcategory distinguishes itself from its sibling, 7616.10.90.90 ("Other"). While the sibling category captures a more general "other" classification for fasteners not otherwise specified, 7616.10.90.30 is precisely for those aluminum fasteners that possess the standard threaded functionality. Therefore, the presence of screw threads is the primary differentiator.

As this is a leaf node in the HTS structure, there are no further subcategories under 7616.10.90.30. Classification at this level is determined by the material (aluminum) and the specific type of fastener (threaded). This implies that all threaded fasteners made of aluminum that do not fall into more specific subheadings (if they existed) would be classified here. It is important to ensure that the goods possess the characteristic threaded design and are indeed made of aluminum to fall within this category.
