Steel, alloy, wire, of silico-manganese steel.
Classification of silico-manganese steel wire under HS 7229.20
Silico-manganese steel wire is classified under HS code 7229.20. According to the Chapter 72 definitions, wire is defined as a cold-formed product in coils, of any cross-sectional shape, that does not conform to the definition of flat-rolled products. Heading 7229 specifically covers "Wire of other alloy steel." For a product to be classified as silico-manganese steel, it must adhere to the chemical composition limits set out in Chapter 72, Note 1(f), which specifies carbon content (≤ 0.7%), manganese (0.5% to 1.9%), and silicon (0.6% to 2.3%). The classification process involves identifying the alloy type first and then the manufacturing process. Since wire is produced by cold-drawing a hot-rolled rod through a die, it is distinct from the rods classified in heading 7227. The subheading 7229.20 provides a specific breakout for this alloy, ensuring that silico-manganese wire is tracked separately from other alloy wires like chrome-vanadium or high-speed steel wire.

Codes often confused with 7229.20
Common mistake. The most frequent misclassification occurs with HS code 7227.20, which covers silico-manganese rods in coils. The difference is that 7227.20 applies to hot-rolled products, while 7229.20 applies to cold-drawn products. If the product has undergone cold-drawing to reduce its diameter, it is wire. Another error is classifying it under 7217, which is for non-alloy steel wire. If the manganese or silicon levels exceed the alloy thresholds, 7217 is incorrect and 7229 must be used.
Top exporters and importers of HS 722920 (the code used for silico-manganese steel wire), 2025
In 2025, the largest exporter of HS 722920 (the code used for silico-manganese steel wire) in UN Comtrade data was China, with 33% of world exports; the largest importer in UN Comtrade data was the United States, with 12% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 722920, not only silico-manganese steel wire.

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).
