7212.30.10.30 - Of a width less than 51 mm, in coils

This HTS category, 7212.30.10.30, specifically covers flat-rolled products of iron or non-alloy steel that have been plated or coated with zinc, and are further characterized by a width of less than 51 millimeters and are supplied in coils. These are often referred to as galvanized steel strips or narrow galvanized steel coils. The key physical attributes are the specific width limitation and the form of presentation as a coil, in addition to the zinc coating.

Within the broader classification of "Otherwise plated or coated with zinc" and further refined by "Of a width of less than 300 mm" and "Of a thickness exceeding 0.25 mm or more," this subcategory distinguishes itself by a more stringent width requirement. While other categories at this level might include wider galvanized steel products, 7212.30.10.30 is exclusively for those with a width strictly under 51 mm. The sibling category, 7212.30.10.90, covers all other galvanized flat-rolled products within the preceding criteria that do not meet the 51 mm width restriction.

As this is a leaf node in the HTS classification system, there are no further subcategories to introduce. Classification under 7212.30.10.30 is definitive based on meeting all the stipulated criteria: being flat-rolled iron or non-alloy steel, plated or coated with zinc, of a width less than 51 mm, and presented in coils, with an implied thickness of 0.25 mm or more from its parent.
