What is the difference?
The difference is in the inner packages one can pack in the box.
4G boxes can only be used by combining the specific inner packaging with which the boxes have undergone the necessary tests.
4G boxes must be packed in the same way as the packaging used in testing:
- same inner packaging
- same use of content (void fill, absorbent, plastic liner(s), etc)
- same type and application of closure of the box
4GV boxes can be used for packing of solid substances and inner packagings of any kind (liquid or solid substances). 4GV fibreboard boxes can be used for dangerous goods of packing groups I, II, III (indicated in the UN approval code on the box with the letter X -> 4GV/X).
For 4GV boxes it is not required to check the inner packagings because these 4GV boxes can contain any type of inner packaging, however the method of packing the box needs to take the following into account:
- the minimum distance between inner packagings and sides, bottom and top of the box, fill with absorbent material and/or void fill (which ever is suitable for the contents)
- the gross weight of the package
- the closing of the box and use special re-enforced tape (i.e. filament tape)
We at DGM Australia make use of our own 4GV tested and approved fibreboard boxes to ensure your cargo is packed in the best way possible, with the various dangerous goods transport regulations complied with.
