Import Tips
• Provide detailed chemical analysis certificates (COA) confirming the exact phosphonite structure and alkyl chain lengths to avoid misclassification
• Ensure SDS includes safety data for phosphorus compounds; common pitfall is inadequate hazard labeling during transport
• Verify purity levels >95% as impurities may trigger reclassification under general organo-inorganic headings
