Overview

This HTS category, 7318.15.50.51, specifically classifies continuously threaded rod made of alloy steel. This includes rods that have been uniformly threaded along their entire length and are intended for use in the manufacture of fasteners or as components where continuous threading is required. The defining characteristic is the material composition, which is alloy steel, distinguishing it from other types of steel.

This category is differentiated from its sibling, 7318.15.50.56 ("Other"), by the specific description of "Continuously threaded rod." While both fall under "Other screws and bolts, whether or not with their nuts or washers" and then "Studs," the sibling category likely encompasses continuously threaded rods that are not of alloy steel, or other forms of threaded rod not meeting the specific alloy steel criteria.

As a leaf node, this category represents the most granular classification for this specific type of article. Therefore, the focus for classification here is on the precise definition of "continuously threaded rod" and the confirmation of its composition as "alloy steel" according to recognized metallurgical standards. This ensures accurate import and export declarations for these specialized threaded components.
