Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If Mullen bursting strength meets kraftliner table minima
Qualifies as kraftliner if strength interpolated matches table for weight >115 g/m², moving to specific kraftliner subheading.
If bleached throughout the mass
Bleached paper and paperboard >225 g/m² falls under 4805.91, differentiated by pulp bleaching process.
If cut to shape or perforated for filter use
Processed into articles like filter paper shifts from paper heading 4805 to paper articles in 4823.

Import Tips & Compliance
• Verify fiber content exceeds 80% sulfate process via lab testing to confirm uncoated status and avoid reclassification
• Provide mill test certificates showing weight >225 g/m² and bursting strength to prevent customs disputes
• Ensure rolls are not further worked (e.g
• no printing) as that shifts to Chapter 49
