Product classification
HS code for Corrugated galvanized iron: 7210.41
Iron or non-alloy steel, flat-rolled, width 600mm or more, corrugated, plated or coated with zinc (not electrolytically).
Classification of corrugated galvanized iron under HS 7210.41
Corrugated galvanized iron (CGI) is classified under HS code 7210.41. This falls under Chapter 72, which covers iron and steel. Heading 7210 is for flat-rolled products of iron or non-alloy steel, of a width of 600 mm or more, clad, plated, or coated. The subheading 7210.41 specifically identifies products that are both corrugated and plated or coated with zinc (galvanized). The corrugation process involves forming the flat sheet into a series of parallel ridges and furrows to increase its structural rigidity, making it ideal for roofing. This specific combination of material (non-alloy steel), width (600mm or more), coating (zinc), and form (corrugated) leads directly to 7210.41. This material is widely used in the construction industry for roofing and siding due to its durability and resistance to corrosion. The classification is very specific about the width; if the product is less than 600mm wide, it would fall under heading 7212. The zinc coating must be applied to the surface of the steel, typically through a hot-dip process, to qualify as galvanized.

Codes often confused with 7210.41
Common mistake. CGI is frequently misclassified under HS code 7210.49, which is for other zinc-coated flat-rolled products that are not corrugated. Another error is using HS code 7308.90, which covers structures and parts of structures. While CGI is used in structures, the sheets themselves are considered base metal products of Chapter 72 unless they have been further worked into identifiable structural components like prefabricated roof trusses.
Top exporters and importers of HS 721041 (the code used for corrugated galvanized iron), 2025
In 2025, the largest exporter of HS 721041 (the code used for corrugated galvanized iron) in UN Comtrade data was China, with 63% of world exports; the largest importer in UN Comtrade data was the Philippines, with 21% of world imports.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
