Hazmat Certification Testing for Packaging

According to the Federal Aviation Administration, “Aviation Safety is dependent on shipping a dangerous good in the correct packaging. If you choose the wrong packaging, you could severely injure a transportation worker, harm the environment, or cause catastrophic damage to an aircraft.”

Hazmat Certification Testing for Packaging is necessary when the material or product is sensitive. Dangerous substances and materials are initially placed in one of nine hazard classes, better known as UN Classes according to their main hazard type (listed below). An assessment is then made of the relative hazard of a substance or material within the same class. Each substance is given an identification number to ensure identification during transit is possible. These identification numbers are commonly known as UN numbers. The UN suggests that all UN numbers be displayed on all transit documents and included on packages, shipping containers, and vehicles along with an official description of the material or substance.

Hazmat Certification Testing for Packaging is Overseen by the United Nations

The storage and transportation of hazardous materials (HAZMAT) is overseen and regulated by federal and international law. A comprehensive marking system called the UN marking guide was developed so that HAZMAT packaging can describe what type and how much of a material may be transported within a package. A UN code is a universal system of demarcation developed by the United Nations and used internationally for the classification, packaging, marking, and labeling of dangerous goods to better transport them safely. Rigorous testing is required before a UN certification mark can be given.

Character Description
The United Nations Coding/Marking System
Type of Package 1 = Drums/Pails
2 = Barrels
3 = Jerricans
4 = Boxes
5 = Bags
6 = Composite Packagings
Material of Construction A = Steel
B = Aluminum
C = Wood
D = Fibre
F = Reconstituted Wood
G = Fiberboard
H = Plastic
Category Type 1 = Closed Head
2 = Open Head
Packaging Group for Container Tested X = Packaging Group I, II, and III
Y = Packaging Group II and III
Z = Packaging Group III

Packaging Group I:
Great Danger – High Hazard Level

Packaging Group II:
Medium Danger – Medium Hazard Level

Packaging Group III:
Minor Danger – Low Hazard Level
Maximum Gross Mass or Specific Gravity Packaging Intended for Solids: (powders, pills, capsules, tablets) or that have inner packaging, this marking will indicate the maximum gross mass (weight) in kilograms.

Packaging Intended for Liquids: Density or Specific Gravity of Material Packed
Solids or Inner Packaging Hydraulic Pressure in Kilo-Pascal (kPa)

For Packaging Intended for Solids or That Have Inner Packaging, Upper Case “S” Will Follow the Gross Mass
Year of Manufacture Current Year
Location of Manufacture Country Where Container Was Manufactured
Manufacturer Code Code for UN Certifying Agency or Manufacturer
