7210.70.60.30 - Electrolytically coated or plated

This HTS category, 7210.70.60.30, specifically covers flat-rolled products of iron or non-alloy steel that have been electrolytically coated or plated with a metallic substance. These products are characterized by their width of 600 mm or more, and they have undergone further processing beyond simple plating, such as being painted, varnished, or coated with plastics. The electrolytic coating process imparts specific protective or decorative properties to the base metal, making it suitable for a range of industrial and consumer applications.

The distinction between this category and its sibling, 7210.70.60.60 (Other), lies in the specific method of metallic coating. While both fall under the broader "zinc coated or plated" designation and have undergone other finishing processes like painting or plastic coating, this subcategory is exclusively for those where the metallic layer was applied through an electrolytic process. This method involves using an electric current to deposit the coating, offering precise control over layer thickness and uniformity, differentiating it from other zinc coating methods.

As this is a leaf node, there are no further subcategories. Classification under 7210.70.60.30 therefore depends on confirming that the flat-rolled iron or non-alloy steel product meets the width requirement, has been painted, varnished, or plastic-coated, and crucially, that the metallic coating applied was specifically achieved through electrolysis. The presence of other metallic coatings applied by different methods would lead to classification in alternative HTS codes.
