Last updated: July 2026 dataPrevulcanized and unvulcanized natural rubber latex — the liquid colloidal form of Hevea brasiliensis sap — is a critical input for dipped goods such as surgical gloves, condoms, and balloons, where film uniformity and protein content are closely monitored. Guatemala leads US supply, followed by Vietnam and Thailand, reflecting a geographically diverse sourcing base that helps importers manage crop-cycle and weather-related supply disruptions. The single US tariff line covering this heading is 4001100000, and the commodity enters duty-free under the general rate. Latex concentrations and ammonia-preservation levels are key specification parameters that affect classification and end-use suitability.

Both prevulcanized and unvulcanized natural rubber latex fall within the same tariff line (4001100000). Prevulcanization — partial cross-linking achieved before dipping — is a processing distinction relevant to end-use performance but does not create a separate classification; the heading explicitly covers both states.
Key parameters include dry rubber content (DRC), total solids content (TSC), ammonia level (high-ammonia vs. low-ammonia grades), mechanical stability time (MST), and volatile fatty acid (VFA) number. These affect shelf life, processing behavior, and suitability for medical versus industrial dipped goods, and should be confirmed against purchase contracts and certificates of analysis.
