Import Tips
• Submit Certificate of Analysis (CoA) showing ≥98% purity to distinguish from mixtures classifiable in heading 3824
• Declare exact stabilizer content if present, as note (f) requires classification with pure compound only if stabilizer is necessary for preservation
• Pre-register with EPA for TSCA and prepare for possible fumigation requirements in wooden chemical drums
