7217.10.80.30 - With a diameter of 1.0 mm or more but less than 1.5 mm

This HTS category, 7217.10.80.30, specifically classifies wire of iron or non-alloy steel that is round in cross-section. The wire is not plated or coated, and it has undergone heat treatment. A key defining characteristic is its diameter, which must be 1.0 mm or more but less than 1.5 mm. Furthermore, this wire contains by weight 0.6 percent or more of carbon, placing it within the category of higher carbon steel wires.

This subcategory is distinct from its siblings based on precise diameter ranges. Specifically, it differs from 7217.10.80.25, which covers round wires with a diameter of less than 1.0 mm, and from 7217.10.80.45, which classifies round wires with a diameter of 1.5 mm or more. The classification hinges entirely on meeting the specified diameter range of 1.0 mm to less than 1.5 mm, in addition to the other qualifying criteria.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification under 7217.10.80.30 requires a definitive match with all preceding criteria: being wire of iron or non-alloy steel, round in shape, not plated or coated, heat-treated, containing 0.6% or more carbon by weight, and falling precisely within the specified diameter range of 1.0 mm to less than 1.5 mm. Examples of such wire might include specific types used in manufacturing applications where the precise tensile strength and flexibility offered by this diameter and carbon content are crucial.
