7616.10.70.30 - Threaded fasteners

This category, HTS 7616.10.70.30, specifically covers threaded fasteners made of aluminum. This includes items such as aluminum screws, bolts, nuts, rivets, and similar articles that are designed to join or secure materials, and importantly, feature threads or shanks exceeding 6 mm in diameter. The classification focuses on the threaded nature and the substantial diameter, differentiating these from smaller fasteners or those not intended for threaded engagement.

It is important to distinguish this category from its sibling, 7616.10.70.90, which is designated for "Other" aluminum articles that do not meet the specific criteria of this threaded fastener classification. Therefore, if an aluminum fastener has threads or holes measuring 6 mm or less in diameter, or if it is not a threaded fastener at all, it would likely fall under the "Other" sibling category, assuming it is not classified elsewhere.

As this is a leaf node within the HTS structure, there are no further subcategories for this specific classification. The classification is definitive for aluminum threaded fasteners with a diameter exceeding 6 mm. Examples of items falling here include substantial aluminum lag screws, large diameter aluminum bolts used in construction or manufacturing, and corresponding aluminum nuts and washers with threads greater than 6 mm.
