Import Tips
• Verify lab test certificates confirming >=88% insoluble fraction in 18% NaOH at 20°C and ash <=0.15% to avoid reclassification
• Include detailed chemical analysis reports in documentation; common pitfalls include insufficient purity proof leading to duty disputes
• Check for sulfite process origin documentation, as blending with other pulps can trigger misclassification
