UN approved packaging and hazardous cargo packs are essential if your business sends items on the UN dangerous goods list within the EU.

UN approved packaging includes boxes, liners and other types of packaging that have been tested and then certified by the United Nations. Manufacturers of hazardous products, including flammable, toxic and corrosive substances, must identify the product with a UN-recognised code and pack and label it accordingly. Read more

About UN dangerous goods packaging

UN approved packaging allows your business to safely send hazardous goods according to current legal requirements.

This is vital if you manufacture or distribute flammable, toxic and corrosive substances. Products, including paint, solvents, adhesives, propane (and similar gasses), acids, perfume, and nail varnish, all require specific UN-approved packaging (including 4G and 4GV packaging).

GWP can supply you with a range of custom UN boxes, specialist liners and absorbent void fill (vermiculite) alongside the relevant testing and certification.

Besides this, a range of standard UN approved packaging is available “off the shelf” for low-volume requirements.

However, GWP design, test and manufacture a pack to satisfy your precise requirements for higher volumes and ongoing requirements. In fact, a team of experts at GWP are happy to handle the whole process for you. This includes initial design, testing, approvals, correct labelling and marking, plus certification.

The result is a space and cost-efficient package that provides the optimum level of protection. GWP’s expertise in various materials and composite packaging allows us to select the most suitable option that still complies with any UN requirement.

Key benefits of UN approved packaging

The key benefits of UN approved packaging are as follows:

  • Allow you to legally and safely ship dangerous goods.
  • Manufactured to exact specifications required by the UN.
  • Provide optimum level of protection for products during transportation.
  • Passes tests relating to stability and water absorption capacity.
  • GWP’s team of experts handles all design, testing and certification.
  • Complete 4-way approval and comply with the design requirements of 4G and 4GV.
  • Range of material options for specific applications, including composite packs.

How do I get UN approval for packaging?

There are several stages involved in getting UN certification for packaging. This includes submitting a request, presenting samples for testing, and conducting the relevant tests before receiving the test report and the issuing of the mark and UN certificate. Your packaging provider should be able to provide this service for you.

What are UN codes?

The UN packaging codes detail the specification of the packaging, as well as showing that it has passed UN testing. The codes also identify the materials (and their characteristics/properties) within the packaging.

What must UN approved packaging be marked with?

UN approved packaging must include correct labelling. Typically, this comprises the approved UN mark, followed by the code that applies to that specific pack/product. These markings allow shipping providers and end users to identify what materials the packaging is suitable for, what the packaging is made from, the maximum weight, plus the year and location of manufacture.

When is UN specification packaging required?

It is a legal requirement that dangerous goods are shipped using UN certified packaging. These laws apply to transportation by ground, air or sea. Paint, perfume, bleach, nail varnish, solvents, propane, acetylene, acids and certain adhesives (amongst other substances) are all hazardous goods.

What is another name for UN approved packaging?

UN approved packaging is also commonly referred to as “hazmat packaging”, “dangerous goods packaging”, “UN certified packs”, and even simply “UN boxes”.

Custom UN approved packaging

AT GWP, we design, manufacture and test your UN packaging so that it not only meets the stringent requirements for dangerous goods but it also provides the optimum performance. We find that this approach offers the best outcome and is more cost-effective for your business in the longer term.

However, the bespoke nature of the UN packs we supply means that we are not able to list prices on this website.
