HS Code for Galvanized alloy steel sheet

The classification of galvanized alloy steel sheet under HS code 7225.92 is strictly governed by the material's chemical composition, its physical dimensions, and the specific nature of its surface coating. According to the Legal Notes to Chapter 72 of the Harmonized System, "alloy steel" is defined by the presence of specific alloying elements that exceed certain weight thresholds, such as 0.3% for aluminum, 0.0008% for boron, or 0.3% for chromium. This product must also meet the definition of "flat-rolled," which refers to products with a rectangular cross-section that does not conform to the definition of "bars and rods." The width is a primary classifier; heading 7225 is reserved for products with a width of 600 mm or more. Subheading 7225.92 specifically addresses those alloy steel sheets that have been plated or coated with zinc using methods other than electrolytic deposition. This typically refers to the hot-dip galvanization process, where the steel is submerged in a bath of molten zinc. This classification follows General Interpretative Rules (GRI) 1 and 6, ensuring that the product is distinguished from non-alloy steel and from narrower strips. The presence of the zinc coating is essential for providing corrosion resistance, making these sheets ideal for automotive and construction applications.

Products Included

• Hot-dip galvanized alloy steel sheets
• Zinc-coated silicon-electrical steel (width 600mm+)
• Alloy steel plates coated with zinc-aluminum alloys
• Corrugated alloy steel sheets with non-electrolytic zinc coating

Common Misclassification

This code is frequently confused with 7210.49, which covers galvanized flat-rolled products of non-alloy steel. The distinction depends entirely on the chemical analysis of the steel. It is also often confused with 7225.91, which is specifically for alloy steel that has been coated electrolytically rather than through hot-dip or other methods. Finally, if the width is less than 600 mm, the product must be classified under heading 7226 regardless of the coating method.

FAQ

What is the HS code for Galvanized alloy steel sheet?

The HS code for galvanized alloy steel sheet with a width of 600 mm or more, coated by non-electrolytic methods, is 7225.92.

What documentation is needed to prove this classification?

Importers should provide a Mill Test Certificate (MTC) that details the chemical composition to prove it meets the "alloy steel" definition and specifies the coating method used during production.
