Import Tips
• Provide process flow diagrams showing chemical pretreatment to distinguish from pure mechanical pulp under 4701
• Label bales with freeness (CSF) values and fiber length data for accurate valuation and quality verification
• Avoid pitfalls by testing for chemical residues; non-compliance can lead to reclassification or penalties
