7212.30.10 - Of a thickness exceeding 0.25 mm or more

This HTS category, 7212.30.10, specifically covers flat-rolled products of iron or non-alloy steel that are of a width less than 600 mm, have been clad, plated, or coated, and are otherwise plated or coated with zinc. Crucially, within this subcategory, it focuses on those items with a thickness exceeding 0.25 mm. These products are typically used in various industrial applications where the protective or decorative properties of zinc coating are required.

This classification distinguishes itself from its sibling category, 7212.30.30.00, which is described as "Other." This implies that 7212.30.10.00 encompasses specific types of zinc-coated, flat-rolled steel products that do not fall under the broader "other" designation of its sibling, likely due to distinct physical characteristics or manufacturing processes not covered elsewhere at this level.

The subcategories within 7212.30.10, namely 7212.30.10.30 ("Of a width less than 51 mm, in coils") and 7212.30.10.90 ("Other"), further refine the classification based on specific dimensions and presentation. The existence of these subcategories suggests that within the broader scope of zinc-coated steel products exceeding 0.25 mm in thickness and less than 600 mm in width, further distinctions are made regarding their width (less than 51 mm) and whether they are supplied in coils. This allows for more precise accounting and tariff application based on product form.
