4002.51.00.00 - Latex

This HTS category, 4002.51.00.00, specifically covers **latex**, which is a dispersion of polymer microparticles in an aqueous medium. In the context of synthetic rubber, this refers to the form in which it is produced or supplied, typically as a liquid emulsion. It is crucial to note that this classification applies to the *latex* form of acrylonitrile-butadiene rubber (NBR).

This classification is distinct from its sibling, 4002.59.00.00, which covers "Other" acrylonitrile-butadiene rubber. While both fall under NBR, 4002.51.00.00 is exclusively for the latex form, whereas 4002.59.00.00 would encompass NBR in other primary forms such as solid blocks, granules, or powders. The physical state and medium of presentation are the key differentiators.

As this is a leaf node, there are no further subcategories under 4002.51.00.00. Classification within this heading is determined by the identification of the material as acrylonitrile-butadiene rubber and its presentation as latex. This implies that any product meeting these criteria, regardless of specific additives or processing unless they fundamentally alter its identity as NBR latex, will fall under this code.
