HS Code for Hot-dip galvanized alloy steel sheet

The classification of hot-dip galvanized alloy steel sheet under HS code 7225.92 is determined by the material composition, the width of the product, and the specific method of coating. According to the Harmonized System, heading 7225 applies to flat-rolled products of alloy steel having a width of 600 mm or more. The subheading 7225.92 is specifically designated for these products when they are plated or coated with zinc by methods other than electrolytic deposition. The hot-dip process involves passing the steel through a molten bath of zinc, which creates a metallurgical bond and a relatively thick protective layer. Because the base metal contains alloying elements such as chromium, nickel, or molybdenum in quantities exceeding the limits defined in Note 1(f) to Chapter 72, it must be classified as alloy steel. The width requirement of 600 mm or more is a critical threshold; if the product were narrower, it would move to heading 7226. Furthermore, the distinction between hot-dip and electrolytic coating is vital, as electrolytic zinc coating is classified under 7225.91.

Products Included

• Hot-dip galvanized alloy steel coils (width ≥ 600mm)
• Zinc-coated alloy steel plates for automotive body panels
• Galvanized high-strength low-alloy (HSLA) steel sheets
• Corrosion-resistant alloy steel flat-rolled products coated in molten zinc

Common Misclassification

This product is frequently confused with HS code 7225.91, which covers alloy steel coated electrolytically with zinc. It is also often misclassified under 7210.49, which is the code for hot-dip galvanized non-alloy steel. The distinction depends entirely on the chemical composition of the steel substrate. Additionally, if the width is less than 600 mm, the correct code would be 7226.99.

FAQ

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

The HS code for hot-dip galvanized alloy steel sheet with a width of 600 mm or more is 7225.92.

How do I distinguish between alloy and non-alloy steel for this code?

Classification as alloy steel requires the presence of specific elements by weight, such as 0.3% or more of aluminum, 0.0008% or more of boron, or 0.3% or more of chromium, as defined in the Chapter 72 legal notes.
