Last updated: August 2026 dataFlexible and rigid polyurethane foam sheet and strip serve the automotive seating, furniture, footwear, and thermal-insulation industries, making this a widely traded industrial input. Like cellular PVC, the US schedule splits the heading by textile backing and fiber content across six 10-digit lines, with 3921131100 and 3921131500 covering man-made fiber combinations and 3921135000 capturing non-backed cellular polyurethane forms. Canada and Mexico are the leading suppliers, consistent with deep automotive and furniture supply-chain integration under USMCA.

The essential character test applies: if the plastic component imparts the primary function and the textile backing is subordinate (e.g., a thin knit backing on foam sheet), classification under 392113 is generally appropriate. If the textile component dominates — for instance, a thick woven fabric with a thin foam coating — the article may classify as a coated textile under Chapter 59. CBP binding rulings are advisable for borderline composite constructions.
Goods meeting USMCA rules of origin from Canada or Mexico are generally eligible for preferential tariff treatment. For cellular polyurethane sheet, the applicable rule typically requires a tariff-shift from chemical inputs or satisfaction of a regional value content threshold. Importers should obtain a valid USMCA certification of origin and confirm rule compliance with their customs broker.
