Import Tips
• Verify chemical composition via lab analysis to confirm lignin sulfonate content meets residual lye criteria
• Obtain certificates of origin proving derivation from wood pulp sulfite process to avoid misclassification
• Ensure proper SDS and waste byproduct documentation, as it may trigger environmental import restrictions
