Overview

This HTS category, 7318.15.20.55, specifically encompasses bolts with round heads that have shanks or threads measuring 6 mm or more in diameter, excluding those made of stainless steel. These fasteners are designed for applications where a round head is required for aesthetic or functional purposes, such as countersinking into a rounded recess or providing a specific bearing surface. The key distinguishing factor for this classification is the presence of a round head combined with the specified diameter and material composition.

It's important to differentiate this category from its sibling, 7318.15.20.51, which covers similar bolts with round heads but are specifically manufactured from stainless steel. This distinction allows for precise tariff treatment based on the material composition, which often impacts corrosion resistance and application suitability.

As this is a leaf node in the HTS structure, there are no further subcategories to introduce. Classification under this code hinges on meeting all preceding criteria: being a bolt with a round head, having a diameter of 6 mm or more, and not being made of stainless steel. Common examples include standard cup-head bolts or carriage bolts with rounded heads that do not fit the stainless steel exclusion.
