Import Tips
• Provide Certificate of Analysis (CoA) confirming ≥99% purity and USP/EP compliance to avoid reclassification as mixtures
• Declare exact CAS number (89-83-8) and chemical name '5-methyl-2-(1-methylethyl)phenol' on commercial invoice for verification
• Ensure packaging prevents sublimation; bulk imports >25kg may trigger TSCA notification if not pre-registered
