7212.20.00.00 - Electrolytically plated or coated with zinc

This HTS classification, 7212.20.00.00, specifically addresses flat-rolled products of iron or nonalloy steel that are less than 600 mm in width and have been electrolytically plated or coated with zinc. The key distinguishing feature of this category is the method of zinc application: *electrolytic deposition*. This process involves using an electric current to deposit a thin layer of zinc onto the steel surface, typically resulting in a smooth and uniform coating.

It is crucial to differentiate this category from its siblings. For instance, HTS code 7212.30 covers products "Otherwise plated or coated with zinc," implying methods other than electrolytic, such as hot-dip galvanizing. Products plated with tin fall under 7212.10.00.00, while those painted, varnished, or coated with plastics are classified under 7212.40. This category strictly pertains to the electrolytic zinc coating method.

As 7212.20.00.00 is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification under this code relies solely on confirming that the flat-rolled iron or nonalloy steel product meets the width requirement (less than 600 mm) and possesses an electrolytic zinc plating or coating. Examples of goods that would fall here include certain types of galvanized steel sheets and coils used in automotive components, appliances, and construction, where the specific electrolytic coating process is applied for corrosion resistance.
