Import Tips
• 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
