'4G' is a UN packaging code for a fibreboard box. It is primarily a handling device, known as the 'outer packaging component' of a combination package used to contain 'inner packagings' that contain dangerous goods. 'V' denotes additional Special Provisions have been met and the carton can be used with a variety of inner packages. All EnLog cartons are 4GV cartons.
Under the UN Recommendations for the Transport of Dangerous Goods, packages must be performance tested "exactly as prepared for transport." In the case of combination packages – this means the completed package, including all inner packaging, cushioning material and all other components, must be subjected to the performance tests as an assembled unit, in the exact configuration that will be used for transport purposes.
A '4G box' on its own is NOT a dangerous goods approved package. A UN 4G is the fibreboard box and is only one component of a combination package. The application of the UN 4G markings to the fibreboard outer packaging constitutes a legal certification on the part of the person applying the markings that the completed package, (not just the fibreboard outer packaging), meets all applicable provisions of the UN 4G standard.
Combination Packaging is packaging consisting of 'outer packaging' (e.g. a fibreboard box) into which is placed one or more 'inner packages' (e.g. glass, or plastic, bottles, metal cans, etc..) the most commonly used combination packages are those employing a fibreboard box as '4G' packaging.
Combination packaging components such as inner packaging, the outer fibreboard box, cushioning materials, caps, gaskets or seals, and tape for closing the assembled box, will most likely come from different suppliers. EnLog's packing service takes full responsibility for assembling these components into the completed package and then marking and certifying the package complies with the 'UN 4G' standards.
All 4GV cartons used by EnLog are branded with the EnLog company logo. As such we take great care to ensure every combination package we prepare is fully compliant and without fault.
