Import Tips
• Verify fiber composition certificate showing ≥80% sulfate/soda wood fibers to confirm kraft classification
• Test for Mullen burst index and stretch per subheading notes to avoid reclassification as lower-grade paper
• Declare exact weight and machine-finished status; common pitfall is misstating g/m² leading to wrong subheading
