Class 3 - Flammable Liquids
Flammable liquids such as mixtures of liquids, liquids containing solids in solution or suspension which give off a flammable vapor at temperatures not more than 60-65°C, liquids offered for transport at temperatures above their flash point or substances which are transported at high temperatures in a liquid state and which give off a flammable vapor at a temperature below the maximum transport temperature.
Sub - Divisions :
This class don't have any sub-divisions but has Packing Groups depending on the boiling point and Flashpoint.
Packing Group 1: Boiling point below 35º C
Packing Group 2: Boiling point above 35º C & Flashpoint < 23º C

Class 4 - Flammable Solids
Solids, Which can spontaneous combustion than ordinary combustible materials such as wood and paper. The burning may be severe and rapid, generating high temperatures. This is usually due to a number of factors like self-reactive, heat up while contacting with air, exothermic reaction.
Sub - Divisions :
Division 4.1: Flammable solids.

Class 5 - Oxidising Agents and Organic peroxides
Substances that can cause or be a part of combustion typically by yielding oxygen as a product of redox chemical reactions. Organic peroxide is a substance formed of organic compounds that are derivative of hydrogen peroxide. where one or both hydrogen atoms of the chemical structure have been replaced by organic radicals. Organic peroxides are unstable.
Sub - Divisions :
Division 5.1: Oxidizing substances
Division 5.2: Organic peroxides
Examples :
‣ Chemical oxygen generators

‣ Potassium chlorate
‣ Potassium nitrate
‣ Potassium chlorate
‣ Potassium perchlorate
‣ Sodium nitrate
‣ Sodium persulphate
Class 6 - Toxic and Infectious substances
Toxic substances are the substances that are liable either to cause death or serious injury or harm human health by swallowing, inhaling, or by skin contact. Infectious substances are substances that are known or expected to contain pathogens.
Sub - Divisions :
Division 6.1: Toxic substances
