Last updated: April 2026 dataA residual category for natural rubber in primary forms — including crepe rubber, air-dried sheets, and other processed forms not captured by smoked sheets or TSNR grades — this heading serves specialty compounders who require specific processing characteristics unavailable in standard grades. Pale crepe and sole crepe, for example, are used in footwear and pharmaceutical applications where color and purity are paramount. Because the heading aggregates diverse processing forms, importers should document the specific rubber type and processing method in entry paperwork to support accurate HTS classification and avoid reclassification at the port.

This heading captures natural rubber in primary forms not classified as latex, smoked sheets, or TSNR — including pale crepe, brown crepe, sole crepe, and air-dried sheet (ADS). Each form has distinct processing characteristics: pale crepe is prized for its light color in footwear and medical applications, while brown crepe is typically produced from lower-grade coagulum and used in general compounding.
Accurate classification requires documenting the specific processing method and physical form — crepe, sheet, or other — on the commercial invoice and entry summary. Because this is a residual heading, CBP may scrutinize whether a product belongs here or under a more specific rubber heading. Working with a licensed customs broker and providing a detailed product specification sheet helps prevent reclassification and potential duty adjustments.
