UN Approved 4GV Boxes

4G in the UN Specification Mark indicates that the packaging is a Fiberboard Box, 4 = box and G = Fiberboard. The letter ‘V’ following the packaging code signifies a “special packaging” conforming to a specific set of requirements as set out in 6.1.5.1.7 of the UN Model Regulations.

For example, gross mass of the inner packagings rules and rules relating to the testing of the packaging, including use of inner types, drop heights & stack test requirements.

4G packaging is tested and approved with specific inner packaging, these inner packaging types must be used in the 4G packaging when shipping hazardous goods, whereas 4GV packaging can be used with appropriate non-specific inner packaging of the shippers choice.

Classified as a box, UN Approved 4GV hazmat boxes can come in many sizes.

We have a range of 4GV boxes, such as our 4GV/X5/S box, which must be shipped with vermiculite as an absorbent packaging material.

If you do not wish to use vermiculite, you can select a 4GV box from our eco range, such as our 4GV/X4/S box, which are approved to be use with biodegradable chips as an absorbent cushioning material.

At Air Sea USA, we can also facilitate the creation of custom made packaging. If you are currently using packaging that isn’t and efficient size or design to accommodate your shipments, you may be able to save money by commissioning custom made packaging.

Creating custom packaging designed to your exact packaging requirements may improve shipping costs. It is perfect for creating effective 4GV packaging for chemicals and other hazardous goods.

Whilst fibreboard is a specific class of cardboard, some people use the terms interchangeably. Officially, the correct terminology used in the transport regulations is Fibreboard, not Cardboard.

4GV hazmat boxes can be used for the shipment of liquids or solids.

They are permitted for the use of transporting packing group I, which means that they are therefore permitted to be used for less hazardous items in packing groups II and III as well.

Also remember that each box has a maximum gross weight limit that will vary from box to box.

One of the special packaging requirements relating to weight for “V” variants is ‘the total combined gross mass of inner packaging shall not exceed one-half the gross mass of inner packaging used for the drop test’.

Shippers must refer to the assembly instructions for the weight information.

To be UN certified, 4GV hazmat boxes must pass:

• Drop tests: Dropped from 1.8 meters with fragile glass inners.
• Stack tests: Tested to ensure the package can handle stacking loads.

Each box must be packed according to the Packing Instructions and manufacturer’s assembly instructions, ensuring compliance with IATA, IMDG and DOT regulations.

Yes. 4GV hazmat boxes meet the IATA Dangerous Goods Regulations and are approved for air transport. They must be packed according to the PI and manufacturer’s assembly instructions, including proper cushioning, inner container selection, and gross weight limits.

If you are purchasing 4GV hazmat boxes for air transport, ensure:

• UN code is compatible with packaging.
• Packaging is permitted on the PI
• The total package weight complies with regulations.
• Inner packaging is properly cushioned with the approved cushioning material for the specific 4GV box, such as vermiculite.
• Correct use of Hazard labels, marking and documentation.

Not necessarily. Many 4GV hazmat boxes require vermiculite, but there are some eco-friendly alternative cushioning materials such as biodegradable chips.

Always check the 4GV box assembly instructions.

To ensure UN compliance, follow the manufacturer’s assembly instructions, typical steps include:

• Choose the correct inner packaging: Make sure it meets the requirements of packing instructions and is compatible with the HazMat.
• Abide to weight restrictions: Check the PI and manufacturers assembly instructions for weight limits.
• Use approved absorbent/cushioning material: Use the absorbent/cushioning as stated on the assembly instructions.
