4001.10.00.00 - Natural rubber latex, whether or not pre-vulcanized

This HTS category, 4001.10.00.00, specifically addresses natural rubber latex, whether or not it has undergone pre-vulcanization. Natural rubber latex is the milky fluid extracted from rubber trees, which retains its elastic properties in liquid form. Pre-vulcanization is a process that chemically alters the latex to improve its stability and processing characteristics. This classification is crucial for distinguishing liquid natural rubber from other forms and derived materials.

It is important to differentiate this category from its siblings. While this node covers natural rubber *latex*, the sibling category "Natural rubber in other forms" would encompass natural rubber that has been processed into solid forms like blocks, sheets, or crumbles, but has not been vulcanized. Furthermore, "Balata, gutta-percha, guayule, chicle and similar natural gums" (4001.30.00) covers distinct types of natural gums, which, while also natural, possess different chemical structures and properties compared to natural rubber.

As this is a leaf node, there are no further subcategories to explore. The classification of natural rubber latex therefore rests on its state as a liquid, its natural origin from rubber trees, and the presence or absence of pre-vulcanization treatment. Importers and exporters should ensure that the form and processing of the natural rubber product accurately align with this specific description to ensure correct customs declaration.
