Shipping of CO2 cylinders

Spare CO₂ cylinders need to be declared as Dangerous Goods which makes international shipping complex. There are two different ways for international shipment of CO₂ cylinders:

A) CO₂ cylinders as part of a life-saving appliance:

Life-saving appliances containing CO₂ cylinders are not subject to the Dangerous Good regulations when carried as cargo. Therefore the sens07vest (including CO₂ cylinder) can be shipped as normal goods. See IATA packing instruction 955 for further information.

B) CO₂ cylinders as an individual spare part:

Individual CO₂ cylinders need to be declared as Dangerous Goods which makes International shipment very complex and expensive. Therefore we strongly recommend purchasing the CO₂ cylinders from a local, national dealer (see list below). The actor module needs to be purchased separately from us, see our store.

List will be constantly extended...

We are able to send you spare CO₂ cylinders by adding a signal tube in order to comply to case A). The specially designed signal tube from ProVitaTec is a life-saving appliance which can be inflated manually or by the included CO₂ cylinder which can also be used for the sens07vest.

Please note that we offer this unusual product as a special service for customers without any possibility to purchase the CO₂ cylinders from a local dealer.

Air traveling with CO2 cylinders


Since 1st January 2019 you can take your inflatable lifejacket systems on board the aircraft. Each passenger may carry one sens07vest and no more than two spare CO₂ cartridges in their luggage. The size limits for CO₂ cartridges in life jackets that apply until the end of 2018 have been lifted, so even the big 95gr CO₂ cartridges should be accepted. These changes were made in the “Dangerous Goods Panel” of ICAO, a sub-organization of the UNO, and incorporated into the ICAO T.I. 2019-2020 released regulations so they are valid worldwide. They were also included in the dangerous goods regulations of the IATA (DGR).


Approval required:

According to ICAO T.I. and IATA-DGR the regulations require the approval of the airline to carry lifejackets (sens07vests).

In order to avoid as many stumbling points as possible in advance, you should contact the airline when booking the flight and point out the request to carry life jacket so this permission can be noted directly on the ticket so usually all discussions are dealt with before arriving at the airport. A reference to the entry on the ticket is sufficient. In individual cases, you will be asked to leave your suitcase at the bulky luggage counter so that it can be separately screened.

Our advice is that you always declare your inflatable lifejacket and CO₂ cartridges, hand in your luggage and not carry them as carry-on baggage. Place the additional replacement cartridges directly alongside the lifejacket so that they can be seen together if the bag is checked.


Check in sens07vest as luggage:

A carry-on as hand luggage is possible. However, staff at the security check of the hand luggage may not be informed and they cannot discuss these new regulations. They often need to ask the supervisor which takes additional time. At the end we always got the CO2 cylinders through the security check. However, there is a risk of unavailable supervisor or insufficient information. Therefore we recommend to check-in your lifejacket as luggage.


No obligation to transport:

The airlines can refuse to take them, because there is no obligation to transport.

Ultimately, it is up to each airline and finally each captain to decide whether he/she allows the passenger, as is their right.
