Last updated: August 2026 dataCotton-filled, innerspring, and other non-foam mattresses classify here, with Indonesia and Canada the leading US suppliers and Poland a notable European source. The heading's structure mirrors the foam-mattress heading: dedicated lines for crib and toddler-bed sizes, a dimensional threshold line for full-size adult units (width over 91 cm, length over 184 cm, depth over 8 cm), and NESOI catch-alls for each construction type. Uncovered innerspring mattress units — sold as components to domestic manufacturers — have their own lines (9404299005, 9404299013, 9404299050), a distinction that matters for both duty treatment and antidumping order scope analysis.

No. Uncovered innerspring units — the spring assembly without a fabric cover — have dedicated lines (9404299005 for crib sizes, 9404299013 for full-size dimensional threshold units, and 9404299050 for others) separate from finished mattresses. This distinction is important for antidumping order scope: some orders cover finished mattresses but not bare innerspring units, or vice versa, so a scope ruling may be warranted.
Poland's presence among the top suppliers reflects European innerspring and pocket-coil mattress manufacturing capacity serving the US market, often at higher price points and with shorter lead times for specialty or private-label programs. European-origin goods are not subject to the Section 301 tariffs that affect Chinese-origin mattresses, which has made them more competitive in certain segments.
