Product classification
HS code for Hot-dip galvanized steel coil: 7210.49
Iron or non-alloy steel, flat-rolled, width 600mm or more, (not corrugated), plated or coated with zinc (not electrolytically).
Classification of hot-dip galvanized steel coil under HS 7210.49
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.

Codes often confused with 7210.49
Common mistake. 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.
Top exporters and importers of HS 721049 (the code used for hot-dip galvanized steel coil), 2025
In 2025, the largest exporter of HS 721049 (the code used for hot-dip galvanized steel coil) in UN Comtrade data was China, with 26% of world exports; the largest importer in UN Comtrade data was Germany, with 7.8% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
