HS code for Steel springs: 7320.90
Iron or steel, springs n.e.c. in heading no. 7320.
Classification of steel springs under HS 7320.90
Steel springs are classified under HS code 7320.90. Heading 7320 is dedicated to springs and leaves for springs of iron or steel. While 7320.10 covers leaf-springs and 7320.20 covers helical springs, the 7320.90 subheading acts as a residual category for all other types of springs. This includes disc springs (often called Belleville washers), flat springs, and certain types of tension or torsion springs that do not meet the definition of helical. The classification depends on the mechanical function of the item—storing energy through elasticity. The material must be iron or steel, and the item must be recognizable as a spring. This heading is quite broad but excludes springs that have been incorporated into other machinery or vehicles if they are presented as part of a larger assembly. However, when imported as individual components for general use or as spare parts, they remain in 7320.90. It is important to note that the manufacturing method (cold-formed or hot-formed) does not usually change the four-digit heading but may affect national-level tariff lines.

Codes often confused with 7320.90
Common mistake. A frequent misclassification occurs with HS code 7320.20, which is specifically for helical springs (coil springs). Many importers label all coiled springs as "helical," but if the spring is a flat-rolled spiral or a disc, it must go to 7320.90. Additionally, springs for watches or clocks are excluded from Chapter 73 and must be classified under HS code 9114.90 as clock or watch parts.

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).
