Unbleached Sack Kraft Paper 80 g/m²
This uncoated kraft paper, weighing 80 g/m², is made from at least 80% sulfate process wood fibers and supplied in rolls for sack manufacturing. It meets subheading criteria for sack kraft with Mullen burst index over 3.7 kPa·m²/g and specified stretch factors, classifying under 4804.39 as other kraft paper under 150 g/m². Not qualifying as kraftliner due to weight below 115 g/m².

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If meets full sack kraft specifications including tear/tensile minima
Strict compliance with sack kraft tear, tensile, and burst specs shifts to dedicated sack kraft subheading.
If weight exceeds 115 g/m² with minimum Mullen bursting strength
Heavier kraft paper qualifying as kraftliner for linerboard use falls under kraftliner subheading.
If less than 80% sulfate/soda fibers
Lower sulfate content makes it other wood-pulped paper, not kraft, under Chapter 48 heading 4802.

Import Tips & Compliance
• Verify fiber composition certificate showing ≥80% sulfate/soda wood fibers to confirm kraft classification
• Test for Mullen burst index and stretch per subheading notes to avoid reclassification as lower-grade paper
• Declare exact weight and machine-finished status; common pitfall is misstating g/m² leading to wrong subheading
