(Please guide us on how to process an overpack where you cannot see the UN specification markings of the packages inside.)

Q.
DGR 7.1.4.1 states: “Unless all markings representative of all dangerous goods in the overpack are clearly visible, …………”. Does this include the UN package specification marking? Furthermore, if the UN package specification marking is placed on the bottom surface of the package, and you can see all the other labels and markings from the outside of the overpack, do we still need to show the word OVERPACK on the surface of the overpack? (30 Jun 13)

A.
Needless to mention, the UN package specification symbol and marking are also to be visible from the outside of the overpack. If the UN package specification marking cannot be seen from the outside, the overpack must carry the word OVERPACK which means that all the packages inside the overpack are UN specification packages. You should not copy the UN package specification marking. The word OVERPACK is there to prove that all packages are UN specification packages.

A package with the UN package specification marking shown on the bottom surface of the package is not according to regulations and must not be accepted or used. DGR 6.0.4.1 clearly spells out that: “all other packagings of combination packages and of composite packages which have been manufactured and tested in accordance with the UN specifications and tests must bear markings which are durable, legible and placed in a location and of such size relative to the package as to be readily visible.” A package with the UN marking on the bottom is not acceptable and cannot be used.。
