7211.23.15.00 - Of high-strength steel

This HTS category, 7211.23.15.00, specifically classifies flat-rolled products of iron or non-alloy steel that meet several precise criteria. The steel must be of a width less than 600 mm and have undergone cold-rolling (cold-reduction). Furthermore, it contains by weight less than 0.25 percent of carbon and has a width of less than 300 mm. Crucially, the material must have a thickness exceeding 1.25 mm and be described as "of high-strength steel." This designation implies specific metallurgical properties and manufacturing processes that result in enhanced tensile strength.

This classification is distinguished from its sibling category, 7211.23.20.00 ("Other"), which serves as a residual category for flat-rolled products meeting the broader criteria of 7211.23 but not specifically designated as "high-strength steel." The key differentiator lies in the metallurgical definition and inherent strength characteristics of the steel in this specific subcategory, which are not necessarily present in the "other" category.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Therefore, classification under 7211.23.15.00 relies on the precise adherence to all the established physical and material specifications outlined, with particular emphasis on the "high-strength steel" designation. Importers and exporters must ensure that the steel product's technical specifications confirm it meets the defined high-strength requirements to be correctly classified here.
