HS code for Innerspring mattress: 9404.29
Mattresses, of other materials, not cellular rubber or plastics.
Classification of innerspring mattress under HS 9404.29
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.

Codes often confused with 9404.29
Common mistake. 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.

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).
