Import Tips

Require DOT special permits for cryogenic liquid hydrogen transport with double-wall vacuum-insulated containers

Provide boil-off rate calculations and pressure relief valve specifications in import documentation

ITAR restrictions may apply for aerospace end-use; coordinate with export controls
