Import Tips
• Maintain supplier certificates detailing the chemical and mechanical steps to support the 4705.00.00 classification
• Verify that the pulp does not meet dissolving grade criteria (insoluble fraction ≥92% for soda/sulphate or ≥88% for sulphite) to avoid reclassification
• Include the chemical charge and refining conditions in your import documentation
