Understanding UN Packaging Certification

UN approved packaging refers to containers tested and certified according to international standards for the transport of dangerous goods.

Each approved box displays a UN marking indicating its performance level (e.g., 4G or 4GV), type of material, and packaging group it supports (I, II or III)

Frequently Asked Questions About UN Approved Packaging

Q1: What is the difference between a 4G and a 4GV box?

A 4G box is a UN-certified fibreboard container approved for use with very specific inner packagings. A 4GV box is more versatile and can be used with a wider range of compatible containers that it doesn't need to be specifically tested for.

Yes, 4GV boxes are tested and approved for both liquid and solid hazardous materials.
