4016.93.50 - Other

This HTS category, 4016.93.50, encompasses a broad range of gaskets, washers, and other sealing articles manufactured from vulcanized rubber, excluding those made from hard rubber and specific automotive applications. These items are designed to prevent leakage of fluids or gases, or to exclude unwanted materials from entering a system. They can be found in a multitude of industrial, commercial, and household applications, playing a critical role in maintaining the integrity and functionality of various equipment and machinery.

Unlike the sibling category 4016.93.10, which is specifically designated for gaskets, washers, and seals of a kind used in automotive goods of Chapter 87, this category covers similar articles intended for all other applications. Therefore, if an article's primary intended use is not within the automotive sector as defined by Chapter 87, it will likely fall under this broader classification. The key differentiator lies in the specific end-use context of the sealing article.

Within this classification, further subdivisions exist to refine the categorization of these sealing articles. The subcategories 4016.93.50.10 (O-Rings) and 4016.93.50.20 (Oil seals) provide more specific classifications for commonly encountered sealing shapes with distinct functional designs. The remaining O-rings and oil seals, as well as all other types of gaskets, washers, and seals not specifically enumerated in the preceding subcategories, are classified under 4016.93.50.50 (Other). This tiered approach allows for greater specificity in import and export data collection and tariff application.
