Guidance on the Continued Use of Existing IMO Type Portable Tanks and Road Tank Vehicles for the Transport of Dangerous Goods

  1. The Sub-Committee on Dangerous Goods, Solid Cargoes and Containers (DSC), at its eighth session (22 to 26 September 2003), recalled that the Maritime Safety Committee, at its seventy-second session (17 to 26 May 2000), had adopted amendment 30-00 to the IMDG Code, which had been prepared in the revised, reformatted and harmonized form of the IMDG Code; and had agreed to an entry into force date of 1 January 2001 with a twelve-month transitional period until 31 December 2001. The reformatted Code included new provisions for the construction and use of multimodal UN portable tanks.
  2. During the reformatting process, the Sub-Committee agreed that existing IMO type portable tanks and road tank vehicles may continue to be used for the life-time of the tank, provided they also comply with the provisions set out in 3.2.1 (column 12) and in 4.2.0 of the IMDG Code. However, the detailed provisions for such tanks, which were contained in section 13 of the IMDG Code, amendment 29-98, were not included in the IMDG Code, amendment 30-00, and its subsequent edition.
  3. The Sub-Committee, noting that IMDG Code amendment 31-02 would attain mandatory status from 1 January 2004, developed the annexed Guidance explaining the provisions of 3.2.1 (column 12) and 4.2.0 of the IMDG Code and reproducing the construction provisions applicable to such tanks.
  4. Member Governments are invited to bring the attached Guidance to the attention of shipowners, ship operators, companies, seafarers and, in particular, tank owners and operators, inspecting and certifying authorities, consignors and shippers, and all other parties concerned with the transport of dangerous goods in packaged form by sea.
