Import Tips

• Verify compliance with Montreal Protocol and EPA regulations on ozone-depleting substances; obtain necessary exemptions or recycling certifications

• Include Safety Data Sheets (SDS) and purity certificates (typically 99.9%+) in documentation to confirm chemical identity

• Avoid misclassification as mixtures; pure dichlorodifluoromethane must meet chapter 29 notes for separate chemically defined compounds
