Products classified under HTS 3920.79.05.00
Vulcanized Fiber Electrical Insulation Sheets
Noncellular plates and sheets made from vulcanized fiber, a cellulose derivative processed with zinc chloride for high density and strength. These are used primarily for electrical insulation in motors and transformers due to their dielectric properties. Classified under HTS 3920.79.05.00 as non-reinforced sheets of vulcanized fiber.
Vulcanized Fiber Shim Stock Sheets
Thin precision sheets of noncellular vulcanized fiber used for shimming in machinery alignment. High tensile strength and machinability without lamination qualify it under this subheading. Specifically HTS 3920.79.05.00 for vulcanized fiber plates, sheets, film, foil, and strip.
Vulcanized Fiber Arc Chute Sheets
Non-reinforced sheets of vulcanized fiber cut for circuit breaker arc chutes to extinguish electrical arcs. The material's heat resistance and non-conductivity make it suitable without chemical modification beyond vulcanization. Classifies in HTS 3920.79.05.00 as vulcanized fiber plates/sheets.
Vulcanized Fiber Nameplate Blanks
Flat noncellular foil and strip of vulcanized fiber for engraving into machinery nameplates. Durable for outdoor exposure without reinforcement. HTS 3920.79.05.00 specifically for vulcanized fiber in these forms.
Vulcanized Fiber Transformer Pressboard
Dense noncellular plates of vulcanized fiber serving as pressboard in oil-immersed transformers. High compressive strength without lamination fits this cellulose derivative subheading. HTS 3920.79.05.00 applies to these unreinforced sheets.
Vulcanized Fiber Knife Handle Blanks
Noncellular sheets and blocks of vulcanized fiber rough-cut for custom knife handles. Moisture resistance and machinability without support classify it here. Under HTS 3920.79.05.00 as other vulcanized fiber plates/sheets.
Vulcanized Fiber Slot Liners
Thin strips and foil of noncellular vulcanized fiber for lining motor stator slots. Provides phase insulation without reinforcement. HTS 3920.79.05.00 for vulcanized fiber in strip/foil form.
Vulcanized Fiber Abrasive Backing Sheets
Non-reinforced vulcanized fiber sheets used as backing for bonded abrasives and sanding discs. Exceptional tear strength suits high-speed applications. Classifies under HTS 3920.79.05.00 as vulcanized fiber plates/sheets.
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.
Vulcanized Fiber Battery End Plates
Rigid noncellular plates of vulcanized fiber used as end insulators in lead-acid batteries. The material's mechanical strength and acid resistance suit it for this application without reinforcement. HTS 3920.79.05.00 covers these as other plates of vulcanized fiber, a cellulose derivative.
