HS Code for Rubber washers

Rubber washers are classified under HS code 401693, which falls within the category of "Other articles of vulcanized rubber other than hard rubber." Heading 4016 is a broad heading for various rubber products that are not specified elsewhere in Chapter 40. Subheading 401693 is specifically dedicated to gaskets, washers, and other seals. These items are characterized by their function: providing a seal between two surfaces to prevent the leakage of fluids or gases, or to provide a cushion. The material must be non-cellular vulcanized rubber. Cellular rubber (sponge or foam rubber) has its own subheading at 401694. The classification process involves verifying that the article is made of rubber that has undergone vulcanization, a chemical process that increases the material's durability and elasticity. If the washer is made of unvulcanized rubber, it would fall under 4006. If it is made of hard rubber (ebonite), it would fall under 4017. The shape of the washer—typically a flat ring—is a defining physical characteristic, but the code also covers more complex sealing shapes. This classification applies to washers used in a wide variety of industries, including automotive, plumbing, and general machinery, provided they are not part of a specialized set classified elsewhere.

Products Included

• Flat rubber washers for plumbing
• Vulcanized rubber O-rings
• Non-cellular rubber gaskets for automotive engines
• Rubber sealing rings for industrial machinery
• Custom-shaped rubber seals for watertight enclosures

Common Misclassification

A common mistake is classifying rubber washers under 401699, which is the "other" category for rubber articles. Since 401693 specifically mentions washers and seals, it takes precedence. Another error involves washers made of plastics, which should be classified under 392690. Furthermore, if rubber gaskets are imported in sets or assortments containing gaskets of different materials (e.g., a kit with rubber, metal, and fiber gaskets), they may be classified under 848410 or 848490 according to the rules for mechanical seals and sets.

FAQ

What is the HS code for Rubber washers?

The HS code for washers, gaskets, and seals made of non-cellular vulcanized rubber is 401693.

Are silicone washers classified under this code?

Yes, since silicone is considered a synthetic rubber in the context of the HS nomenclature, silicone washers are classified under 401693.
