The Transportation Security Administration (TSA) does not permit the carrying of filled pressure cartridges on flights arriving into or departing from the USA, or on internal flights within the USA. This regulation also applies to passengers transferring between flights in the USA.

Any cartridge carried into the USA must be completely discharged and the valve must be removed from the cartridge body for the security check.
The following cartridges cannot therefore be transported to the USA since after discharging they cannot be refilled locally in the USA:
- Carbon Cartridge Non-Refillable 300 Bar
- Cartridge Non-Refillable 300 Bar Steel
Customers with these cartridges are recommended to hire a cartridge locally during their stay in the USA.
The following cartridges can be discharged in preparation for transport to the USA and then refilled locally:
- Cartridge Refillable 207 Bar Alu
- Cartridge Refillable 207 Bar Alu empty
The cartridge can be refilled in diving shops and paintball venues. However, we recommend that you use an official Mammut/Snowpulse cartridge refilling station.
