Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing mechanical fibers >10%
Exceeding mechanical fiber limit reclassifies to wood-containing paper subheading.
If used as kraftliner with high burst strength
If meeting kraftliner specs (80% sulfate fibers, >115 g/m², Mullen strength), shifts to packaging paperboard.
If surface-coated for inkjet
Paper coated for graphic arts or inkjet use moves to heading 4811.

Import Tips & Compliance
• Obtain mill test report confirming Mullen burst strength and fiber analysis; declare as 'not for printing' to prevent duty disputes
• Pitfall: Importing in pre-cut sheets may trigger 4820 if punched/perforated
