HS Code 7229.20 – Steel, alloy; wire, of silico-manganese steel
HS code 7229.20 is the 6-digit subheading for steel, alloy, wire, of silico-manganese steel. It is used for silico-manganese spring wire, valve spring wire, suspension spring wire, torsion bar wire and high-strength wire for fasteners.
What HS 7229.20 covers
This HS code covers wire made from silico-manganese alloy steel, a specific type of alloy steel known for its excellent spring properties. The addition of silicon and manganese enhances the steel's strength, elasticity, and fatigue resistance, making it ideal for applications requiring high resilience and durability under repetitive stress. This wire is predominantly used in the manufacturing of various types of springs, including valve springs, suspension springs, and industrial springs, which are critical components in the automotive industry, general machinery, and electrical appliances. International trade in silico-manganese steel wire is driven by the global demand for high-performance spring components. Countries with robust automotive and precision manufacturing sectors are key importers, while specialized steel wire producers are the primary exporters, focusing on quality and consistent mechanical properties.

Codes often confused with 7229.20
Common mistake. Can be confused with 722990 (other alloy steel wire) if the specific silico-manganese composition is not identified, or 7217 (non-alloy steel wire) if the alloy content is overlooked.
Top exporters and importers of HS code 722920, 2025
In 2025, the largest exporter of HS code 722920 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.

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).
