Import Tips
• Verify compliance with Montreal Protocol phase-out schedules and EPA import restrictions on ozone-depleting substances
• Include Safety Data Sheets (SDS) and purity certificates to confirm chemical identity and meet HTS classification requirements
• Check for country-specific quotas as HCFC imports face strict volume limitations and allocation certificates
