HS Code for Innerspring mattress

The classification of an innerspring mattress falls under HS code 9404.29. Chapter 94 covers furniture, bedding, and similar stuffed furnishings. Heading 9404 specifically includes mattress supports and articles of bedding fitted with springs or stuffed or internally fitted with any material. Within this heading, mattresses are subdivided by material. Subheading 9404.21 is strictly for mattresses made of cellular rubber or plastics, such as memory foam or latex. Consequently, mattresses that utilize metal springs as their primary support structure—even if they contain layers of foam, felt, or textile padding—are classified under 9404.29, which covers mattresses of "other materials." This classification is based on the internal structural components of the mattress rather than the external ticking or upholstery. The presence of the spring unit is the defining characteristic that moves the product from the cellular plastic category to the residual "other" category.

Common Misclassification

Innerspring mattresses are most commonly misclassified under 9404.21, which is only for mattresses made entirely or primarily of cellular rubber or plastics (foam). They may also be confused with 9404.10, which covers mattress supports (box springs) that do not have a sleeping surface. Another error is using 7320, which covers iron or steel springs, but as a finished article of bedding, the mattress must stay in 9404.

FAQ

What is the HS code for innerspring mattress?

The correct HS code for a mattress containing metal springs is 9404.29.

Does this code apply to hybrid mattresses?

Yes, if the mattress contains an internal spring system combined with foam layers, it is generally classified under 9404.29 because it is not exclusively made of cellular materials.
