7217.30.15.30 - Containing by weight 0.6 percent or more of carbon

This HTS classification, 7217.30.15.30, specifically covers flat wire made from iron or non-alloy steel that has been plated or coated with base metals other than precious metals or metal carbides. The defining characteristic of this subcategory is its carbon content, which must be 0.6 percent or more by weight. This precise carbon threshold is a key determinant for distinguishing it from other flat wires within the broader "plated or coated with other base metals" category.

The distinction from its sibling category, 7217.30.15.60 ("Other"), lies in the explicit carbon content requirement. While the sibling category encompasses all other plated or coated flat iron and non-alloy steel wires not meeting the 0.6% carbon threshold, this classification is reserved for those meeting or exceeding that specific carbon percentage. Therefore, when classifying a flat wire product, its carbon composition is a critical factor in determining whether it falls into this specific subcategory or the broader "other" category.

As this is a leaf node within the HTS, there are no further subcategories. Classification decisions at this level will depend directly on verifying the material composition (iron or non-alloy steel), the form (flat wire), the coating (other base metals), and critically, the carbon content by weight (0.6% or more). Examples of goods that would fall here include certain types of spring steel wire or high-carbon steel wire that have been plated or coated for corrosion resistance or other functional purposes.
