Import Tips
• Verify purity levels (>99.5%) via Certificate of Analysis to confirm classification as chemically defined styrene, avoiding mixtures under Chapter 27
• Include Material Safety Data Sheets (MSDS) documenting inhibitor content (e.g
• TBC) as stabilizer permitted under Chapter 29 note 2(f)
• Ensure proper UN1266 hazmat labeling and IBC/steel drum packaging compliant with DOT regulations for flammable liquids
