HS Code 7227.20 – Steel, alloy; bars and rods, hot-rolled, in irregularly wound coils, of silico-manganese steel
HS code 7227.20 is the 6-digit subheading for steel, alloy, bars and rods, hot-rolled, in irregularly wound coils, of silico-manganese steel. It is used for silico-manganese spring wire, automotive suspension spring coils, railway buffer springs material, industrial valve spring stock and leaf spring material.
What HS 7227.20 covers
This HS code pertains to silico-manganese alloy steel bars and rods, hot-rolled and supplied in irregularly wound coils. Silico-manganese steel is highly valued for its excellent strength, toughness, and elasticity, making it a preferred material for springs, particularly in automotive suspension systems and industrial machinery. The international trade involves specialized steel mills exporting these coils to spring manufacturers and automotive component suppliers globally. Importers are typically large-scale manufacturers in the automotive, railway, and heavy machinery sectors. Trade flows are heavily influenced by the health of the global automotive industry and infrastructure development. Buyers prioritize consistent mechanical properties, fatigue resistance, and formability for subsequent processing into finished springs, ensuring reliability in critical applications.

Codes often confused with 7227.20
Common mistake. Often confused with other alloy steel bars in coils (722790) if the specific 'silico-manganese' alloy type is not correctly identified, or with non-alloy spring steel if the alloy content is overlooked.
Top exporters and importers of HS code 722720, 2025
In 2025, the largest exporter of HS code 722720 in UN Comtrade data was China, with 35% of world exports; the largest importer in UN Comtrade data was the United States, with 19% 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).
