3812.39.90.00 - Other 🖩

This HTS subcategory, 3812.39.90.00, encompasses "other" anti-oxidizing preparations and compound stabilizers for rubber or plastics that are not specifically listed elsewhere within the 3812.39 heading. These are formulated mixtures designed to prevent or slow down the degradation of rubber and plastic materials caused by factors such as oxidation, heat, UV radiation, or ozone. Their purpose is to enhance the longevity, performance, and appearance of rubber and plastic articles.

This classification is distinct from its sibling, 3812.39.70.00, which specifically covers Bis(1,2,2,6,6-pentamethyl-4-piperidinyl) sebacate, a particular type of hindered amine light stabilizer (HALS). Therefore, 3812.39.90.00 applies to a broader range of stabilizer formulations that do not fall under that specific chemical designation. The key differentiating factor lies in the precise chemical composition and intended application of the stabilizer, where this category captures those not explicitly named.

As this is a leaf node, there are no further subdivisions within 3812.39.90.00. Classification within this category relies on determining that a product functions as an anti-oxidizing preparation or compound stabilizer for rubber or plastics and does not fit into any more specific HTS classification, particularly the named sibling category. Importers should carefully review the composition and function of their product against the definitions of general anti-oxidizing and stabilizing agents for polymeric materials.
