WORK OF THE SUB-COMMITTEE OF EXPERTS ON

THE TRANSPORT OF DANGEROUS GOODS

Packing Instructions

Information Paper from the International Maritime Organisation (IMO)

1.	During its last session (14-23 September 1998) the DSC Sub-Committee's Editorial and Technical Group (E&T Group) considered the introduction of Packing Instructions into the reformatted IMDG code.

2.	For packagings, the special packagings prescribed in the current IMDG code for classes 2, 3, 4.1, 4.2, 6.1, 8 and 9 were compared with the outcome of the Frankfurt Working Group.

3.	For IBCs, the maritime related concerns made by some delegations during the Frankfurt Working Group were considered.

4.	The two foregoing paragraphs clearly indicate that the work at IMO is not finalised and further remarks may be expected.

5.	The ensuing paragraphs highlight the changes agreed by the E&T Group without the formal approval of the DSC Sub-Committee for consideration of the Committee.
