The line on the transport document

ADR 5.4.1.1.1 asks for the UN number, the proper shipping name, the labels (or the class), the packing group and the tunnel code, in this order and with nothing in between. For each entry:

  • UN 3166 VEHICLE, FLAMMABLE GAS POWERED, 9, (─)
  • UN 3166 VEHICLE, FLAMMABLE LIQUID POWERED, 9, (─)
  • UN 3166 VEHICLE, FUEL CELL, FLAMMABLE GAS POWERED, 9, (─)
  • UN 3166 VEHICLE, FUEL CELL, FLAMMABLE LIQUID POWERED, 9, (─)
  • A special provision in Column (6) can change the labels; read the special provisions in the table below before you print.
  • The tunnel code is needed only when the route passes a tunnel with restrictions; "(─)" is written where Table A gives none.
  • Quantity, packages, consignor and consignee complete the document (5.4.1.1.1 (e) to (h)).
