3812.39.70.00 - Bis(1,2,2,6,6-pentamethyl-4-piperidinyl) sebacate

This HTS code, 3812.39.70.00, specifically classifies Bis(1,2,2,6,6-pentamethyl-4-piperidinyl) sebacate. This chemical compound is a type of hindered amine light stabilizer (HALS). HALS are crucial additives used in plastics and rubber to protect them from degradation caused by ultraviolet (UV) radiation and heat, thereby extending the product's lifespan and maintaining its physical properties.

Within the broader category of "Anti-oxidizing preparations and other compound stabilizers for rubber or plastics," this specific code distinguishes itself from its sibling, 3812.39.90.00 ("Other"), by its precise chemical identity. While the sibling category encompasses other unlisted compound stabilizers and anti-oxidizing preparations, 3812.39.70.00 is dedicated solely to this particular sebacate ester derivative, which is recognized for its effectiveness in light stabilization applications.

As this is a leaf node, there are no further subcategories under 3812.39.70.00. Therefore, the classification here is final for Bis(1,2,2,6,6-pentamethyl-4-piperidinyl) sebacate. Importers and exporters must ensure that the product being declared precisely matches the chemical description and function of Bis(1,2,2,6,6-pentamethyl-4-piperidinyl) sebacate to fall under this classification. Documentation supporting the chemical identity and intended use as a light stabilizer is essential for accurate customs processing.
