Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If Mullen bursting strength meets kraftliner table minima
Qualifies as kraftliner for corrugating medium if strength thresholds like 393 kPa at 115 g/m² (interpolated) are met.
If weight 60-115 g/m² with sack kraft tear/tensile specs
Lighter grammage with specific burst index >3.7 kPa·m²/g and stretch moves it to sack kraft paper subheading.
If mainly from recovered waste paper pulp
Testliner from recycled fibers with Mullen burst index ≥2 kPa·m²/g falls under fluting paper made from waste.

Import Tips & Compliance
• Verify fiber content exceeds 80% sulfate process fibers via lab testing to confirm kraft classification and avoid reclassification
• Provide mill test certificates showing grammage 150-225 g/m² and burst strength to clear customs without delays
• Ensure rolls are over 36 cm wide; narrower widths may shift to heading 4802
