Machine-Finished Sack Kraft Paper 80 g/m²
This uncoated sack kraft paper, made from at least 80% sulfate or soda process wood fibers, weighs 80 g/m² and meets the Mullen burst index and tensile strength specs for subheading 4804.21/29. It is supplied in rolls for manufacturing multi-wall paper sacks used in packaging industrial goods.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If weight >115 g/m² with Mullen bursting strength ≥393 kPa
Qualifies as kraftliner paperboard, a heavier variant under different strength criteria.
If machine-finished but failing exact tear/tensile minima
Still sack kraft but may fall under 'other' if not meeting precise interpolated specs.
If mainly from recovered waste paper pulp
Recycled content dominant shifts to fluting/testliner papers in 4805.

Import Tips & Compliance
• Verify fiber composition certificate showing ≥80% sulfate/soda wood fibers to qualify under 4804
• Provide Mullen burst index and tensile test reports matching subheading specs to avoid reclassification
• Declare exact grammage (60-115 g/m²); exceeding limits shifts to kraftliner under 4804.11/19
