Import Tips

Verify compliance with Montreal Protocol and EPA phaseout schedules; HCFC-22 imports are restricted post-2020 for non-refill uses

Include Safety Data Sheets (SDS) and cylinder certifications; ensure DOT-compliant packaging for hazardous material transport

Avoid misclassification as mixtures; pure HCFC-22 must meet 99%+ purity without additives exceeding chapter note limits
