HS Code for Steel springs

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.

Products Included

• Disc springs (Belleville springs)
• Flat springs
• Spiral springs (non-helical)
• Torsion bar springs
• Clock-type springs (general use)

Common Misclassification

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.
