Vulcanized Fiber Gaskets and Washers
Thin noncellular sheets and strips of vulcanized fiber cut into gasket and washer forms for mechanical seals. Vulcanized fiber's oil and water resistance makes it ideal for automotive and machinery applications. Falls under HTS 3920.79.05.00 as unreinforced plates, sheets, or strip of this cellulose derivative.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If further fabricated into finished gasket assemblies with adhesives
Articles of plastics not specially provided for, including complex gasket sets, go to 3926.90.
If impregnated with phenolic resin during manufacture
Fabricated asbestos-fiber products or chemically modified beyond vulcanized fiber classify under Chapter 68.
If made from vulcanized rubberized fiber
Rubber gaskets shift to Chapter 40; material predominance rules apply per polymer notes.
