2930.20.90.20 - Products used principally for rubber processing

This HTS classification, 2930.20.90.20, specifically covers products utilized primarily for the processing of rubber. These are organo-sulfur compounds that fall within the broader family of thiocarbamates and dithiocarbamates, but are not intended for use as pesticides. The defining characteristic for classification under this subheading is their functional application within the rubber manufacturing industry, serving as accelerators, antioxidants, or other essential additives that modify the properties and processing of rubber.

This category is distinguished from its sibling, 2930.20.90.10, by its intended use. While both fall under "Other" thiocarbamates and dithiocarbamates, 2930.20.90.10 is reserved for compounds classified as pesticides. Therefore, products classified under 2930.20.90.20 are solely for industrial rubber processing applications and do not possess pesticidal properties. The other sibling, 2930.20.90.50, represents a further "Other" category for thiocarbamates and dithiocarbamates that do not fit into the pesticide or rubber processing classifications.

As this is a leaf node, there are no further subcategories. The classification is determined solely by the product's identity as a thiocarbamate or dithiocarbamate and its principal use in rubber processing. Importers must ensure that the intended application and composition of the imported goods align precisely with the definition of products used for rubber processing to ensure accurate classification.
