7225.92.00.00 - Otherwise plated or coated with zinc

This HTS category, 7225.92.00.00, encompasses flat-rolled products of other alloy steel, with a width of 600 mm or more, which are otherwise plated or coated with zinc. This classification applies to alloy steel, as defined by Chapter 72 of the Harmonized Tariff Schedule, that has undergone a zinc coating process not specifically covered by other subheadings within 7225.9. The key distinguishing feature is the *method* of zinc application.

This category is distinct from its sibling, 7225.91.00.00, which specifically covers flat-rolled products of other alloy steel that are *electrolytically* plated or coated with zinc. Therefore, 7225.92.00.00 applies to zinc plating or coating that is achieved through methods other than electrolysis, such as hot-dip galvanizing or other mechanical or chemical deposition processes. The distinction lies in the specific technological process employed for the zinc coating.

As this is a leaf node, there are no further subcategories. Classification within this heading hinges on determining that the product is indeed "other alloy steel," is flat-rolled with a width of 600 mm or more, and has been coated with zinc via a method that is not electrolytic. Practical application would involve examining manufacturing documentation or the physical characteristics of the coating to confirm the plating process.
