UN Testing Information

We offer a number of UN-Rated packaging kits to meet your needs.  Our kits have been tested by our DOT-certified testing partner, TEN-E.  Here's an overview of the required tests packages must pass:


Package Preparation

  • 5 packages are prepared exactly as they would be for transportation.
  • The testing lab will use water in place of the hazardous material and place additives in the water to vary the specific gravity to match what is actually being shipped.


Drop Tests

  • Each package is then dropped from a specific height, determined by the Packing Group of what is being shipped. Any breakage or leaking voids the package.
  • 1 Drop for every prepared sample (5 total).
    • Top Side
    • Bottom Side
    • Corner
    • Short Side
    • Long Side


Stack Tests

  • These are done by stacking packages on each other to make sure they are strong enough that they won’t collapse.


Vibration Tests

  • These are done to simulate the package traveling by motorized vehicle (boat, plane, train, truck).


Cobb Water Absorption

  • This is done on the actual fiberboard box to make sure the paper used is of high enough quality and that it won’t disintegrate with moisture.


Pressure Differential

  • This is done for Air Transport Only when the primary inner container will contain liquid.
  • Due to pressure variation when traveling by air, this is done to show the container won’t leak.


Once a package has been able to successfully pass all of the tests above, it will then be UN approved and be permanently marked or embossed with a UN marking.


New tests are performed on new packages and when any design changes occur in an existing package. Once a package is tested, it must go through a periodic retest. Combination Packaging must be retested every 24 months. Single Packaging (pails, drums, etc.) must have a periodic retest at least every 12 months.
