Last updated: July 2026 dataFoam and latex mattresses — whether open-cell polyurethane, memory foam, or cellular rubber — are classified here, with or without fabric covers. The US schedule subdivides the heading by end-use and dimension: crib and toddler-bed sizes (9404210010), oversized adult mattresses exceeding specified width, length, and depth thresholds (9404210013), and a residual NESOI line (9404210095). Indonesia and Vietnam are the dominant suppliers, reflecting the concentration of foam-processing capacity in Southeast Asia, and imports from both countries have been subject to antidumping scrutiny in recent years. Buyers should verify country-of-origin documentation carefully, as production shifting among regional suppliers has made substantial-transformation determinations a recurring compliance issue.

The schedule breaks out crib and toddler-bed mattresses (9404210010) as a separate line, then carves out large adult mattresses exceeding 91 cm in width, 184 cm in length, and 8 cm in depth (9404210013), with all other cellular rubber or plastics mattresses falling into the NESOI line (9404210095). Correct classification depends on precise measurements and the intended end-use of the mattress.
Yes. Mattresses from several Southeast Asian countries, including Vietnam and Indonesia — the top two suppliers under this heading — have been subject to antidumping and circumvention investigations. Importers should monitor Commerce Department orders and scope rulings, as misclassification or circumvention findings can result in retroactive duty liability.
