HS code for Spring mattress: 9404.29
Mattresses, of other materials, not cellular rubber or plastics.
Classification of spring mattress under HS 9404.29
Spring mattresses are classified under HS code 9404.29, which falls within Chapter 94 of the Harmonized System. This chapter covers furniture, bedding, and mattresses. Specifically, heading 9404 encompasses mattress supports and articles of bedding or similar furnishing. The classification 9404.29 is designated for mattresses made of materials other than cellular rubber or plastics, whether or not covered. Because spring mattresses rely on a core of metallic springs (such as Bonnell, offset, or pocket coils) rather than a solid block of foam, they are excluded from the 9404.21 subcategory and placed into the residual 9404.29 category. The classification remains consistent regardless of whether the mattress includes additional layers of padding, such as felt, wool, or textile fibers, provided the primary structural support is derived from the spring unit.

Codes often confused with 9404.29
Common mistake. Spring mattresses are frequently misclassified under HS code 9404.21, which is reserved strictly for mattresses made of cellular rubber or plastics (like memory foam or latex). Another common error is using HS code 9401, which covers seats and sofas; however, even if a mattress is used on a sofa bed, it remains classified under 9404 when imported as a separate component. Additionally, mattress toppers without springs are classified under 9404.90 rather than 9404.29.

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).
