7223.00.10.31 - With a diameter of 0.25 mm or more but less than 0.76 mm

This HTS classification covers stainless steel wire with a specific diameter range. Specifically, it applies to round stainless steel wires that have a diameter greater than or equal to 0.25 mm but less than 0.76 mm. This category falls under the broader heading of "Wire of stainless steel," originating from Section XV of the Harmonized Tariff Schedule, which deals with base metals and articles thereof, and specifically Chapter 72 for iron and steel.

The defining characteristic of this classification is its precise dimensional requirement. It is distinct from sibling categories that cover thinner wires (less than 0.25 mm) and thicker wires (0.76 mm or more). The crucial differentiator for 7223.00.10.31 lies in its placement within the established diameter intervals for stainless steel wire.

As this node is a leaf node in the HTS structure, there are no further subcategories. Therefore, classification into this code is determined solely by meeting the specified diameter criteria for stainless steel wire. Examples of goods that would fall under this classification include fine stainless steel wire used in medical devices, specialized industrial applications requiring precise wire dimensions, or components for electronics where specific tensile strength and diameter are critical.
