IATA Dangerous Goods Classes & Regulations – Oxidising Substances & Organic Peroxides

An in-depth look at one of the nine IATA classes of dangerous and hazardous goods – Class 5 Oxidising Substances & Organic Peroxides


Shipping Class 5 Dangerous Goods

There is a total of nine dangerous/hazardous goods classes that are used day in and day out within the logistics sector. Each item/product/good that when transported are a risk to safety, health or the environment needs to be categorised into one of those classes.

On the Tudor Website you will find information in respect of each class of the nine dangerous goods categories. If you want a full overview of what you need to consider when shipping dangerous goods, be sure to check out our previous blog here.


What is a Class 5 Dangerous Good?

Class five of the nine dangerous goods refers to ‘oxidising substances and organic peroxides’. These in turn are split into their own separate sub divisions as seen below.

Division 5.1: Oxidising Substances

These substances can cause fire or play a part to something causing a fire after exposure to oxygen. Although oxidisers are not necessarily flammable on their own, the mixture of oxygen and other materials can cause a chemical reaction that in turn will create combustion.

Division 5.2: Organic Peroxides

Organic Peroxides are likely to combust individually. An organic peroxide is formed purely of organic compounds which are derivative of hydrogen peroxide. Due to their nature, organic peroxides are thermally unstable and give off mass heat
