Capacitor Grade Unbleached Kraft Separator Sheet
Sheets of unbleached kraft paper optimized as separators in electrolytic capacitors, under 150 g/m². Classified in HTS 4804.31.20.00 for other condenser applications, leveraging kraft's strength and purity.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If sulfite wrapping paper with >40% sulfite fibers and burst index ≥1.47
Sulfite process fibers and wrapping specs classify under 4805.30 subheading.
If roll width ≤15 cm
Narrow rolls ≤15 cm are excluded from 4804, moving to 4803 for thin rolls.
If cut to size, stamped or embossed but not retail ready
Processed paper cut to size or embossed falls under 4821, not base paper of 4804.

Import Tips & Compliance
• Use commercial invoices detailing end-use in capacitors to justify condenser subclass
• Prevent blending errors; pure kraft fiber certification avoids 4805 classification
• For sheets, confirm not cut-to-size for machines, or it may go to 4823 per notes
