Electrical Condenser Tissue Paper
Ultra-thin, high-purity kraft paper designed specifically for use as dielectric insulation in electrical capacitors and condensers. It is uncoated, weighs under 150 g/m², and meets the precise dielectric strength requirements for high-voltage applications. Classified under HTS 4804.39.20.00 as condenser paper, a specialized kraft paperboard not covered by headings 4802 or 4803.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If weighing 60-115 g/m² and meeting sack kraft specifications
Sack kraft paper has defined tensile/tear minima for packaging; electrical condenser paper lacks these mechanical specs.
If produced via chemical wood pulp but not qualifying as kraft
Heading 4802 covers other chemical pulp papers; kraft requires ≥80% sulfate/soda fibers per subheading notes.
If cut to size or shape for retail sale as individual sheets
Chapter notes exclude cut-to-size sheets from heading 4820 only if not qualifying; finished condenser tissue sheets become articles.

Import Tips & Compliance
• Verify dielectric strength certification and exact grammage (<150 g/m²) via lab testing to confirm classification as condenser paper
• Provide manufacturer specs proving electrical insulation purpose; misclassification as generic kraft risks re-assessment
• Ensure roll or sheet format; pre-cut sheets may shift to heading 4820 if not qualifying as paper in bulk
