7217.10.20.00 - Of a thickness exceeding 0.25 mm but not exceeding 1.25 mm

This HTS category, 7217.10.20.00, specifically classifies wire of iron or nonalloy steel that is neither plated nor coated, and has been polished. Crucially, the defining characteristic for this classification is the wire's cross-sectional thickness, which must exceed 0.25 mm but not exceed 1.25 mm. This category is for wire that meets the specified thickness range and material composition (less than 0.25% carbon by weight), excluding any surface treatments like plating or coating.

This classification distinguishes itself from its siblings based on precise thickness tolerances. HTS code 7217.10.10.00 covers similar wire with a thickness *not exceeding* 0.25 mm, while HTS code 7217.10.30.00 pertains to wire with a thickness *exceeding* 1.25 mm. Therefore, this category acts as a middle ground, capturing products falling within a very specific dimensional band.

As this is a leaf node within the HTS, there are no further subcategories. Classification decisions within this node hinge solely on the confirmed wire material (iron or nonalloy steel with low carbon content), the absence of plating or coating, and the critical thickness measurement falling between 0.25 mm and 1.25 mm, inclusive of the lower bound and exclusive of the upper bound.
