Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If ≤30 g/m² wallpaper base stock
Lighter weights and end use shift to heading 4802.
If predominantly waste paper pulp with burst ≥2 kPa·m²/g
Recovered pulp main content moves to testliner fluting.
If imported as filter paper stock pre-perforation
Specialty end use like Jacquard cards covered in 4823.

Import Tips & Compliance
• Partner with accredited labs for pre-shipment spec verification
• Segment rolls by exact weight; mixed shipments risk partial reclassification
• No perforations/embossing at import; post-conversion may hit 4823
