Import Tips
• 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
