Import Tips & Compliance
• Verify purity ≥99% to confirm classification under 2914.12; mixtures may shift to Chapter 38
• Include Material Safety Data Sheet (MSDS) and ensure UN 1193 hazardous labeling for DOT compliance
• Avoid retail packaging over 1L as it risks reclassification under 3824 for prepared solvents
