Overview

This HTS subcategory, 7318.15.20.51, specifically classifies bolts with round heads that are made of stainless steel. These are threaded fasteners designed for joining materials, characterized by their cylindrical shank and the presence of a rounded head. This classification applies when these stainless steel bolts, along with any accompanying nuts or washers entered in the same shipment, have shanks or threads with a diameter of 6 mm or more.

Distinguishing this category from its sibling, 7318.15.20.55 ("Other"), is the precise head shape. While both cover stainless steel bolts with a shank or thread diameter of 6 mm or more that are entered with their nuts or washers, this subcategory is exclusively for those with *round* heads. The "Other" category would encompass stainless steel bolts meeting the diameter and shipment criteria but featuring different head shapes, such as hex, square, or pan heads.

As this is a leaf node, there are no further subcategories. The classification is finalized based on the material (stainless steel), fastener type (bolt), head shape (round), diameter, and whether accompanying nuts or washers are shipped concurrently. Therefore, accurate identification relies on confirming all these defining characteristics.
