Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made mainly of straw pulp
Straw-based fluting paper with CMT 30 >1.4 N/g/m² weighing ≥130 g/m² falls under 4805.12, distinct from hardwood semichemical.
If kraftliner with ≥80% sulfate wood fibers
High-strength kraftliner paper >115 g/m² with specified Mullen burst qualifies for 4804.11, not fluting medium.
If mainly from recovered waste paper
Fluting with Mullen burst index ≥2 kPa·m²/g from recycled pulp shifts to 4805.24, excluding virgin semichemical.

Import Tips & Compliance
• Verify CMT 30 crush resistance exceeds 1.8 N/g/m² at 50% RH and 23°C with lab certification to confirm 4805.11 classification
• Provide mill test reports detailing ≥65% unbleached hardwood semichemical fibers to avoid reclassification as other fluting types
• Import in rolls only; sheets may shift to 4823 if cut to size, triggering different duties
