Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If sack kraft 60-115 g/m² meeting tear/tensile specs
Sulfate sack kraft paper under 4804.21 if for bags, not electrical use.
If loose cut sheets or cards
Chapter note excludes cut-to-size sheets from 4820, but may apply if not rolls.
If wallpaper base or impregnated
Further worked surfaces like impregnation go to 4814.

Import Tips & Compliance
• Provide pore size and burst strength data matching condenser standards to prevent shift to general 4805
• Use ISPM-15 compliant reels for rolls to avoid fumigation delays
