HS Code for Hot-dip galvanized steel coil

The classification of hot-dip galvanized steel coil under HS code 7210.49 is strictly governed by the material composition, dimensions, and the specific method of surface coating. This code applies to flat-rolled products of iron or non-alloy steel. A primary requirement is the width, which must be 600mm or greater. The defining characteristic is that the steel has been plated or coated with zinc. Specifically, this subheading covers products where the zinc is applied via the hot-dip process—submerging the steel in a bath of molten zinc—rather than through electrolytic deposition. Furthermore, the product must not be corrugated; corrugated zinc-coated sheets are classified under 7210.41. The steel must also be "non-alloy," meaning it does not contain elements like chromium, nickel, or molybdenum in quantities that would classify it as alloy steel under Chapter 72, Note 1(f). This classification is essential for distinguishing standard industrial galvanized coils from specialty electrolytic or corrugated products. The material is typically used in construction, automotive body parts, and household appliances where corrosion resistance is paramount.

Products Included

• Hot-dip galvanized steel coils (HDGC)
• Zinc-coated non-alloy steel sheets in coils
• Galvanized wide strip (width >= 600mm)
• Non-corrugated zinc-plated flat-rolled steel

Common Misclassification

This code is frequently confused with HS code 7210.30, which covers flat-rolled iron or non-alloy steel that is electrolytically plated or coated with zinc. The distinction lies in the application method; hot-dip (7210.49) results in a thicker, more durable coating compared to the thinner electrolytic layer (7210.30). Additionally, if the product is corrugated, it must be classified under 7210.41. If the width of the coil is less than 600mm, it falls under heading 7212.

FAQ

What is the HS code for hot-dip galvanized steel coil?

The HS code for hot-dip galvanized steel coil (non-alloy, width 600mm or more, not corrugated) is 7210.49.

What is the difference between HS 7210.49 and 7210.30?

HS 7210.49 refers to steel coated with zinc via a hot-dip molten bath, while 7210.30 refers to steel coated via an electrolytic process.
