Vulcanized Fiber Electrical Insulation Sheets from Germany
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.

Import Tips
• Verify material composition via lab testing to confirm vulcanized fiber content meets 95% polymer requirement per subheading notes
• Provide certificates of analysis documenting noncellular structure and absence of reinforcement or lamination
• Avoid misclassification as paper products; highlight chemical modification from cellulose to vulcanized fiber in documentation
