3812.20.10.00 - Containing any aromatic or modified aromatic plasticizer

This HTS category, 3812.20.10.00, specifically classifies compound plasticizers for rubber or plastics that contain any aromatic or modified aromatic plasticizers. Plasticizers are additives that increase the plasticity or fluidity of a material. In this context, the defining characteristic is the presence of aromatic compounds, which are organic compounds containing one or more benzene rings, or derivatives of these, used to enhance flexibility, durability, and processing of polymers.

This subcategory is distinguished from its sibling, 3812.20.50.00, which covers "Other" compound plasticizers. The key differentiator lies in the chemical composition; 3812.20.10.00 exclusively includes those plasticizers formulated with aromatic or modified aromatic components, whereas the "Other" category encompasses all compound plasticizers that do not meet this specific aromatic criterion, such as those based solely on aliphatic or other non-aromatic chemistries.

As this is a leaf node, there are no further subcategories. Therefore, classification within 3812.20.10.00 hinges directly on the presence of aromatic or modified aromatic plasticizing agents in the compound. Importers and exporters should carefully review the chemical composition of their plasticizer products to ensure accurate classification, paying particular attention to the molecular structure and the type of plasticizing agent employed.
