Electrical Condenser Tissue Paper
Ultra-thin, high-purity paper in rolls weighing under 150 g/m², specifically designed for use as dielectric insulation in oil-filled electrical capacitors. It meets the precise specifications for condenser paper under HTS 4805.91.20.00 due to its uncoated nature, low weight, and suitability for high-voltage applications without further processing.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If electrical properties not certified for condensers
Falls to general other uncoated paper ≤150 g/m² without specific condenser tissue qualifications.
If coated on both sides with ≤15 g/m² per side
Coated lightweight paper shifts to chapter 48 heading 4810 for surface-treated products.
If cut to size sheets for retail sale
Processed beyond rolls/sheets into sized/filter paper articles moves to heading 4821.

Import Tips & Compliance
• Verify paper meets condenser-specific electrical insulation standards (e.g
• low conductivity, high dielectric strength) with mill test certificates to avoid reclassification
• Provide documentation proving weight ≤150 g/m² and uncoated status; common pitfall is misdeclaring as lightweight coated paper under 4810
• Confirm not further worked (e.g
• no impregnation); inspect for chapter note 3 compliance on processing limits
