Import Tips
• Verify fiber content via lab testing to confirm >95% chemical wood fibers and uniform bleaching for 4804.42 classification
• Provide mill test certificates showing grammage (150-225 g/m²) and Mullen burst strength to avoid reclassification as heavier paperboard
• Ensure documentation specifies 'folding carton stock' end-use to prevent shifts to general kraft paper subheadings
