HS Code 7320.20 – Iron or steel; helical springs and leaves for springs
HS code 7320.20 is the 6-digit subheading for iron or steel, helical springs and leaves for springs. It is used for coil springs, compression springs, extension springs, torsion springs and valve springs.
What HS 7320.20 covers
This category covers helical springs made of iron or steel, which are ubiquitous in a vast array of applications, from automotive suspension systems (coil springs) to industrial machinery, consumer electronics, and even medical devices. Unlike leaf springs, helical springs offer compact design and versatile performance characteristics, making them indispensable components in modern engineering. The global trade involves a complex supply chain, with specialized spring manufacturers exporting to diverse industries worldwide. Importers range from large-scale automotive assembly lines and industrial equipment manufacturers to smaller workshops and distributors. Exporters are typically nations with advanced manufacturing capabilities and a strong focus on precision engineering. Factors like material composition, spring rate, fatigue life, and corrosion resistance are critical trade considerations, driving demand for high-quality, reliable components.

Codes often confused with 7320.20
Common mistake. Often confused with 732010 (leaf springs) due to general 'springs' classification, but 732020 is specific to helical designs. Also, 870880 for vehicle suspension parts might overlap, but 732020 is for the spring itself.
Top exporters and importers of HS code 732020, 2025
In 2025, the largest exporter of HS code 732020 in UN Comtrade data was China, with 30% of world exports; the largest importer in UN Comtrade data was Mexico, with 13% 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).
