4016.93.10.20 - Oil seals

This HTS classification, 4016.93.10.20, specifically covers oil seals made from vulcanized rubber, excluding hard rubber. These seals are designed and manufactured for use in the automotive vehicles falling under Chapter 87 of the Harmonized Tariff Schedule. Their primary function is to prevent the leakage of oil or other lubricants and to exclude contaminants, thereby ensuring the proper functioning and longevity of automotive components such as engines, transmissions, and axles.

Distinguishing this category from its siblings, 4016.93.10.10 specifically identifies O-rings, which are a particular type of circular sealing ring. While O-rings are also oil seals, this classification is for oil seals that are not O-rings, implying other shapes and designs tailored for specific sealing applications within automotive systems. The sibling category 4016.93.10.50, "Other," would encompass any gaskets, washers, or seals of vulcanized rubber (other than hard rubber) that are not oil seals and are not O-rings, for automotive use.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, the classification is considered definitive for oil seals of vulcanized rubber, used in automotive applications, that are not O-rings. Classification hinges on the material being vulcanized rubber (other than hard rubber) and the intended application being within the automotive vehicles referenced in Chapter 87, distinguishing it from general-purpose industrial seals or seals for other types of machinery.
