7215.10.00.10 - Containing by weight 0.1 percent or more of lead

This HTS category, 7215.10.00.10, specifically classifies bars and rods of iron or non-alloy steel that are classified as "free-cutting steel" and have undergone cold-forming or cold-finishing processes. The defining characteristic for inclusion in this subcategory is the presence of 0.1 percent or more of lead by weight within the steel's composition. This lead content enhances the machinability of the steel, allowing for faster cutting speeds and improved tool life during manufacturing processes.

This classification distinguishes itself from its sibling category, 7215.10.00.80 ("Other"), by its specific lead content requirement. While both fall under bars and rods of free-cutting steel, not further worked than cold-formed or cold-finished, the "Other" category would encompass similar steel types that do not meet the minimum lead threshold or are distinguished by other characteristics not explicitly defined within this leading subcategory.

As this is a leaf node in the HTS classification system, there are no further subcategories under 7215.10.00.10. Therefore, the primary focus for classification within this code remains on confirming that the bars or rods are made of free-cutting steel, have been cold-formed or cold-finished, and crucially, contain at least 0.1 percent lead by weight.
