Last updated: September 2026 dataNBR latex — the emulsion form of nitrile rubber — is the primary raw material for dipped nitrile examination and industrial gloves, a sector that has seen sustained demand growth in healthcare and food-processing applications. South Korea leads US import supply, with Malaysia a close second; both countries host major latex-dipping industries that drive upstream NBR latex demand. The single applicable tariff line is 4002510000. Acrylonitrile content grade (low, medium, or high nitrile) is a key specification variable that buyers should document on commercial invoices.

Acrylonitrile content — typically ranging from roughly 18% to 50% — directly determines the latex's oil resistance, flexibility at low temperatures, and suitability for specific end products such as gloves or seals. While HTS classification does not subdivide by acrylonitrile level, buyers and customs brokers should include the grade specification on commercial invoices and purchase orders to support quality control, end-use verification, and any downstream product certification requirements.
NBR latex is an industrial chemical intermediate and does not trigger mandatory FSIS, FDA, or APHIS admissibility review. Standard CBP entry procedures apply, though importers should ensure compliance with EPA TSCA inventory requirements for chemical substances and verify that the product's CAS number is listed or exempt.
