Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If uncoated
Uncoated kraftliner falls under base kraft paperboard heading without kaolin or inorganic coating.
If lightweight <72 g/m² with mechanical wood fibers
Light-weight coated paper with mechanical pulp base shifts to subheading 4810.22, not kraft.
If made mainly from recovered waste paper
Recycled content paperboard with Mullen burst index ≥2 kPa·m²/g classifies under 4805.24 fluting paper.

Import Tips & Compliance
• Verify fiber composition meets 80% sulfate wood fiber requirement via lab testing to confirm kraft classification
• Provide Mullen burst test certificates matching subheading 4804.11 specs for customs valuation
• Avoid misclassification as graphic paper by ensuring no writing/printing intent; declare packaging end-use
