Your guide to UN certified packaging

Our UN carton range and UN certified containers enable you to package and transport dangerous goods in total safety

UN Carton

The first objective when packaging and transporting dangerous goods is to ensure that the contents do not escape. Consequently we stock a range of specialised containers that have been developed to meet these requirements. In addition our range of UN certified fibreboard cartons are also available to hold and protect the inner containers. In order to obtain UN certification both the inner UN certified container and the outer UN carton must be tested together. It is important to ensure that only the correct size and type of inner containers are used.

The approved combination of inner UN container and outer UN carton must have been tested and they are identified by UN specification marking, of which this is an example:

The UN codes for packing are:

  1. Drums/Pails
  2. Barrels
  3. Jerricans
  4. Box
  5. Bag
  6. Composite Packaging

Approved construction materials are:

A. Steel
B. Aluminium
C. Natural Wood
D. Plywood
F.     Reconstituted Wood
G.    Fibreboard.
H.    Plastic Material

L. Textile
M. Paper, multi-wall
N. Metal (other than aluminium)
O. Glass, porcelain or stoneware (not used in these regulations

Selecting the correct fibreboard UN carton is most important and requires the following information:

  •  The UN number or proper shipping name of the dangerous goods being shipped
  •  The amount of dangerous goods being shipped
  •  The physical dimensions and weight of the inner packaging that the substance will be shipped in

Only once you have this information can it be determined if the fibreboard UN carton is suitable for the contents.

At Patrico we supply a wide range of UN cartons that are available from stock and are manufactured to approved UN fibreboard specifications. These are available in both 4G and 4GV standards.

4G UN Carton
Both the carton and inner container must be tested and approved together. It is critical that only the correct inner containers are used as per the license. If required we can provide a testing service for you.

4GV UN Carton
4GV specification cartons can be used with a variety of non-tested inner packs. Very often the inner containers are packed with vermiculite granules to provide additional protection.

 Our 4GV outer UN carton range offers an extensive choice of sizes and capacities and they are designed to hold a wide range of inner containers, including Drums, Pails, Barrels and Jerricans manufactured from a variety of materials including plastic, and steel.
