Unbleached Kraft Condenser Tissue Paper
Thin unbleached kraft paper designed for use as condenser tissue in electrical capacitors, weighing under 150 g/m² and in rolls or sheets. It meets the specifications for 'other' kraft condenser paper under 4804.31.20.00 due to its high purity and dielectric properties from sulfate wood fibers. This paper is essential for insulation in high-voltage capacitors.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If bleached
Bleached kraft paper and paperboard weighing 150 g/m² or less falls under 4804.39, changing from unbleached subheading.
If weighing over 150 g/m²
Higher weight uncoated kraft paper exceeds the 150 g/m² threshold, moving to 4802.59 for heavier grades.
If imported as part of assembled electrical capacitors
When incorporated into finished insulating components of capacitors, it is classified by end-use under electrical machinery heading 8547.

Import Tips & Compliance
• Verify fiber content exceeds 80% sulfate or soda wood fibers via lab testing to confirm kraft classification and avoid reclassification
• Provide mill test certificates showing weight ≤150 g/m² and dielectric strength to support condenser paper use during customs entry
• Ensure no coating or printing; uncoated status is critical, as coated paper shifts to heading 4810
