Last updated: April 2026 dataLiquid-phase unvulcanized rubber—whether dissolved in solvent or dispersed in aqueous or non-aqueous media—enters under 4005200000 and is distinct from carbon-black or silica compounds, which have their own heading. These formulations serve adhesive, coating, and dipping applications in industries ranging from glove manufacturing to textile lamination. South Korea and Germany lead US supply, with Italy, the United Kingdom, and Japan also significant sources, pointing to a supplier base concentrated in advanced chemical-processing economies.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
A solution involves rubber fully dissolved in a solvent, yielding a homogeneous liquid, while a dispersion (latex-type) consists of rubber particles suspended in a medium. Both forms classify under 4005200000 as long as the rubber is unvulcanized and the compound is not based on carbon black or silica, which would redirect it to heading 400510.
Yes—CBP may query whether a shipment is natural rubber latex (heading 4001) or a compounded rubber solution (4005200000). The distinction turns on whether the material is a compounded formulation with added chemicals versus raw or concentrated latex. Detailed technical documentation from the manufacturer is advisable to support the correct classification.
