Import Tips

Obtain FDA registration if intended for medical oxygen production post-import to ensure regulatory compliance

Provide engineering drawings showing liquefaction cycle to confirm classification over general cooling equipment

Avoid delays by pre-clearing with CBP on cryogenic insulation materials that may trigger additional inspections
