HS Code for Rubber gaskets

Rubber gaskets, washers, and other seals are classified under HS code 4016.93. This classification falls under the broader heading 4016, which covers articles of vulcanized rubber other than hard rubber. Gaskets are essential components used to prevent leakage between two joined surfaces. The classification 4016.93 is specific to seals made of non-cellular vulcanized rubber. According to the Section XVI notes and Chapter 40 notes, these items remain in Chapter 40 even if they are intended for use in specific machinery, provided they are not part of a set or assortment of gaskets of different materials. The material must be vulcanized to ensure it is no longer thermoplastic, providing the necessary heat and chemical resistance required for sealing applications. This code covers a wide range of industrial and consumer sealing components that do not contain metal reinforcements that would change their primary classification to a composite article.

Products Included

• Rubber O-rings and circular seals
• Flat rubber gaskets for plumbing or automotive use
• Rubber washers for bolts and fasteners
• Oil seals made of vulcanized rubber
• Mechanical seals for pumps and valves

Common Misclassification

A common misclassification occurs with HS code 8484.10, which covers gaskets and similar joints of metal sheeting combined with other material or of two or more layers of metal. If a rubber gasket is reinforced with metal or is part of a multi-material kit, it may move to 8484. Additionally, gaskets made of cellular rubber (foam) are classified under 4016.10. Purely plastic gaskets are classified under 3926.90. It is vital to determine the exact material composition and whether the item is a single material or a composite before assigning the code.

FAQ

What is the HS code for rubber gaskets?

The standard HS code for gaskets made of vulcanized non-cellular rubber is 4016.93.

Are silicone gaskets classified under 4016.93?

Yes, since silicone is considered a synthetic rubber elastomer in the context of the Harmonized System, silicone gaskets are generally classified under 4016.93.
