7222.20.00.41 - Containing less than 8 percent by weight of nickel

This HTS category, 7222.20.00.41, specifically covers bars and rods of stainless steel that have been cold-formed or cold-finished, and are of a circular cross-section with a maximum diameter measuring less than 18 millimeters. Crucially, these products must contain less than 8 percent by weight of nickel. The "other" designation at this level indicates that these are stainless steel bars and rods that do not fall under more specific subheadings within the broader category of cold-formed or cold-finished bars and rods.

The primary distinguishing factor for this specific subheading, 7222.20.00.41, lies in its nickel content. It is differentiated from its sibling category, 7222.20.00.43, which covers similar stainless steel bars and rods that contain 8 percent or more but less than 24 percent by weight of nickel. Therefore, the precise chemical composition, particularly the percentage of nickel, is the decisive criterion for classifying goods under either of these subheadings.

As this is a leaf node within the HTS, there are no further subcategories to introduce. Classification under 7222.20.00.41 is final once the criteria of being a cold-formed or cold-finished stainless steel bar or rod with a circular cross-section under 18 mm in maximum dimension, and containing less than 8 percent nickel by weight, are met. Practical application would involve verifying these physical dimensions and analyzing the material's composition to ensure accurate customs declarations.
