Product classification
HS code for Coil springs: 7320.20
Iron or steel, helical springs and leaves for springs.
Classification of coil springs under HS 7320.20
Coil springs are classified under HS code 7320.20, which falls within the chapter for articles of iron or steel. Heading 7320 specifically covers springs and leaves for springs, of iron or steel. The classification process follows the material-based logic of the Harmonized System. Under GRI 1, the heading is determined by the material composition and the specific function of the article. Subheading 7320.20 is reserved for helical springs, which include the common coil variety used in various mechanical applications. Even when these springs are intended for use as components in machinery (Chapter 84) or vehicles (Chapter 87), they are generally classified under 7320 because they are considered "parts of general use" as defined in Note 2 to Section XV. This note stipulates that springs of base metal are to be classified in their own respective headings regardless of their intended end-use, unless they are specifically excluded by other section or chapter notes. The helical design, characterized by a wire wound into a cylindrical or conical shape, is the defining physical attribute for this subheading. This ensures a uniform classification for compression, tension, and torsion coil springs made from steel wire or rod.

Codes often confused with 7320.20
Common mistake. A frequent misclassification occurs under HS code 8708.80, which covers suspension systems and parts for motor vehicles. While coil springs are used in suspensions, they must be classified under 7320.20 as parts of general use unless they are imported as part of a complete strut or shock absorber assembly. Additionally, they are sometimes confused with 7320.90, which is a residual category for other types of springs like disc springs or flat springs.
Top exporters and importers of HS 732020 (the code used for coil springs), 2025
In 2025, the largest exporter of HS 732020 (the code used for coil springs) 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.
Figures cover everything classified under HS 732020, not only coil springs.

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).

Questions about coil springs
What is the HS code for Coil springs?
The HS code for Coil springs is 732020 (Iron or steel; helical springs and leaves for springs). The HS code for helical coil springs made of iron or steel is 7320.20.
How do I classify Coil springs for customs?
Coil springs is classified under HS code 732020 — Iron or steel; helical springs and leaves for springs. This is a 6-digit subheading level code.
Are stainless steel coil springs classified differently?
No, stainless steel is a type of steel, so helical springs made from it still fall under the 7320.20 classification.
Which countries are the top exporters of coil springs (HS 732020)?
In 2025, the top exporters of HS 732020 (the code used for coil springs) in UN Comtrade data were China ($1.5B, 30% of world exports), Germany ($936M) and the United States ($518M). World exports came to about $5.1B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of coil springs (HS 732020)?
In 2025, the top importers of HS 732020 (the code used for coil springs) in UN Comtrade data were Mexico ($547M, 13% of world imports), Germany ($414M) and the United States ($412M). World imports came to about $4.1B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Is the HS code for Coil springs the same in all countries?
The base HS code 732020 for Coil springs is internationally standardized for the first 6 digits across 200+ countries. Individual countries may add additional digits for national tariff lines and specific classifications.
What is the NCM code for coil springs in Brazil?
Brazil splits HS 732020 into 2 NCM codes, so the right one for coil springs depends on the product's details: 7320.20.10 (Cylindrical helical springs of iron or steel), 7320.20.90 (Other helical springs of iron or steel).
