I am travelling with my caravan – what counts as hazardous goods?

 Gas Cylinders

A maximum of 3 cylinders of butane/propane (the combined weight of which must not exceed 47 kg) is allowed for lighting, cooking or heating purposes only. All cylinders must be adequately secured against movement of the ship with the supply shut off at the cylinders during the voyage. Leaking and inadequately secured or connected cylinders will be refused shipment. Any gas cylinders to be carried must be declared at the time of booking. Partially full or empty cylinders will be treated as if they are full. A maximum of 6 cylinders of medical oxygen for personal use may be carried, provided a letter from the user's doctor is provided stating that they require medical oxygen.

As per the latest Marine Guidance Note (MGN 545), customers can carry

  • a maximum of 5 litres of petrol / diesel per vehicle
  • in an approved container i.e. container sold for the purpose of fuel transportation only (red/green plastic can.  The metal ones would be of the old jeep jerrycan design
  • for travel from the UK to the Continent and Republic of Ireland (UK to Northern Ireland can ship both ways)
  • in a private vehicle not in commercial use.

For travel from the Continent to the UK:

  • fuel cans, if carried, must be empty
