HS Code for Spring mattress

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.

Products Included

Common Misclassification

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.
