7318.15.60.70 - Of stainless steel

This HTS category, 7318.15.60.70, specifically classifies screws and bolts made of stainless steel, where the shank or thread has a diameter measuring less than 6 millimeters. These fasteners are intended for joining materials, and their designation as "other" within the broader "other screws and bolts" grouping indicates they do not fall into more specific, previously listed subcategories for this diameter range. The stainless steel composition is a key defining characteristic, offering corrosion resistance and durability, differentiating these items from those made of other iron or steel alloys.

The immediate sibling category, 7318.15.60.80, also covers "other" screws and bolts with a shank or thread diameter of less than 6 mm, but it is not limited to stainless steel. Therefore, the critical distinction lies in the material composition. While both categories capture fasteners of a similar size and general type, 7318.15.60.70 is exclusively for those fabricated from stainless steel, a premium material for applications requiring enhanced resistance to rust and environmental degradation.

As this HTS code represents a leaf node, there are no further subcategories. Classification at this level is definitive, meaning goods meeting the criteria of stainless steel screws and bolts with a diameter under 6 mm will be classified here, provided they do not fit into more specific preceding categories within the 7318 heading. Practical classification will rely on confirming the material (stainless steel) and the precise diameter of the threaded portion or shank.
