Nitrile O-Ring for Automotive Fuel Injectors
A vulcanized nitrile rubber O-ring designed for sealing fuel injector connections in gasoline engines. It falls under HTS 4016.93.50.10 as an O-ring, which is a specific type of gasket, washer, or seal made from vulcanized rubber other than hard rubber. The circular cross-section and sealing function classify it here.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as part of a complete gasket kit or machinery assembly
Placeholders for gaskets and similar joints of any material in Chapter 84 take precedence over Chapter 40 rubber articles.
If not strictly an O-ring shape, e.g., D-ring or custom seal profile
Other vulcanized rubber seals beyond standard O-rings fall into the broader 'other' category within the same heading.
If for motor vehicle-specific use and imported as OEM part
Parts and accessories of motor vehicles may classify under Chapter 87 if specifically designed and principally used for vehicles.

Import Tips & Compliance
• Verify material composition via lab testing to confirm it's vulcanized rubber and not hard rubber, as hard rubber excludes from Chapter 40
• Provide detailed technical specs and end-use certification to avoid misclassification as machinery parts under Chapter 84
• Ensure FDA compliance if used in fuel systems contacting food-grade components to prevent regulatory delays
