Electrical Pressboard Insulation Sheet from Germany
Uncoated pressboard in sheets weighing 180 g/m², made from densely compressed wood fibers for high dielectric strength. Classified under HTS 4805.92.20.00 as pressboard, which is other uncoated paperboard >150 but <225 g/m², not further worked. Used primarily in transformers and electrical equipment for insulation.

Import Tips
• Verify grammage between 150-225 g/m² via lab testing to confirm subheading; exceeding limits shifts to other weights
• Provide mill test certificates showing fiber composition and density to prove pressboard status and avoid reclassification
• Ensure no coatings or further processing; common pitfall is misdeclaring laminated versions which go to 4811
