Import Tips
• Provide Certificate of Analysis confirming purity >98% as chemically defined compound per Chapter 29 note (a)
• Declare exact CAS number (109-89-7) on entry; impurities must not exceed 2% to avoid reclassification
• Ensure UN 2685 hazmat labeling for corrosive liquid; common pitfall is missing SDS documentation
