4G Corrugated Hazmat Boxes

4G hazmat boxes are a specialized type of UN compliant packaging designed to ensure the safe transportation of hazardous materials.

The material used for UN approved fibreboard boxes consists of layers of corrugated fibreboard, a type of cardboard that is made from wood pulp. The corrugated layers (also called fluting) are designed to increase the strength and durability of the material.

The design of 4G hazmat boxes meets stringent requirements for shipping various hazardous materials, including solvents, chemicals, petrochemicals and other HazMat. By providing robust protection, these corrugated boxes help prevent leaks, spills and damage during transit, ensuring that hazardous materials are transported safely and in compliance with DG regulations.

4G is a term used for fibreboard boxes that have been UN approved.

The code 4G is displayed in the UN specification mark that is assigned to and printed on the packaging.

In this case, 4 denotes that the package is a box and the G denotes that it is made of fibreboard.

UN specification marks indicate that the packaging corresponds to a successfully tested design type and that it complies with the relevant provisions set out in dangerous goods regulations.

It allows businesses, shippers, handlers and appropriate authorities to identify the type of packaging and a number of performance related information.

Further details of performance criteria which the packaging meets can be found on the test certificate.

The correct description as per dangerous goods regulations  is 4G Fibreboard Box.

It is a form of outer packaging that is used for the shipment of hazardous goods when used with appropriate inner packaging.

4G boxes are tested with specific inners and once approved, those inner types must be used within the 4G box, using any other inner type will invalidate the UN test certification.

For example, if the 4G box was tested and UN certified with 4x 100ml glass bottles, then you must use these inners.

You cannot use the same box for 2 x 200ml plastic bottles as these have not been tested for use with this box.

Our corrugated 4G hazmat boxes would act as a layer of protection for the inner packaging and goods being transported, and prevent damages occurring from knocks or drops during handling and transport, it prevents any leaks from escaping the container and being released.

Some common 4G fibreboard box uses:

• 4G Fibreboard Boxes for solvents
• 4G Fibreboard Boxes for flammable liquids
• 4G Fibreboard Boxes for chemical samples

Our hazmat boxes are manufactured using corrugated fibreboard and are thoroughly tested to ensure compliance with UN dangerous goods regulations.

Tests vary depending on the packaging type, but can include, drop test, stack test and pressure tests to simulate how the material would perform under real life transport conditions.

As 4G boxes are outer packaging, they are tested and approved to be used with specific inner packaging materials.

You must ensure that you are using the approved inner packaging with the outer packaging before transport.

The package must be assembled as it was during testing.

We provide assembly instructions which are printed as QR codes on all our 4G boxes.

Both 4G boxes and 4GV boxes are made of fibreboard and both provide good levels of protective support for dangerous goods when being shipped.

The packaging may look the same but there are subtle differences between the two which shippers may not be aware of.

4G boxes have been tested with specific inner packaging and must be used with that inner packaging, 4GV can be used with ‘V’ various suitable inner packaging.

We have written an article to help explain the main differences between 4G and 4GV packaging.

No – the shipper must refer to the packing instruction for their hazardous goods to ensure they are using permitted packaging for the UN number in question.

To ensure that your 4G packaging is compliant with dangerous goods regulations, always look for the UN specification mark on the packaging.

This mark provides information on the packaging’s design, weight allowance and other information. a UN Mark indicates that the packaging has UN certification.

Yes, UN approved 4G packaging can be used for shipping various hazardous materials across borders.

However, it’s important to check the relevant dangerous goods modal regulations to check the packaging requirements surrounding your HazMat any special provisions of the carrier or destination.

The gross weight capacity of a 4G box depends on the specific testing it has undergone.

The gross weight capacity will be indicated on the UN specification mark.

Yes, when using 4G corrugated packaging to ship hazardous materials, appropriate hazard labels and markings are required to ensure safety during transport.

This may include:

• The specific UN number.
• The proper shipping name of the hazardous material.
• Weight
• Hazard Labels

These labels and markings must be clearly visible on the outer packaging, as per dangerous goods regulations.
