value to people.
• The finished product has more value 
and utility than the raw material 
that it is made from.

ON THE BASIS OF RAW MATERIALS
• Agro-based industries 
• use plant and animal based products as their raw 
materials.
• Mineral -based industries are primary industries that 
use mineral ores as their raw materials. 
• Iron made from iron ore is the product of mineral based 
industry.
• Marine- based industries use products from the sea 
and oceans as raw materials. 
• Forest- based industries utilize forest produce as raw 
materials.

ON THE BASIS OF SIZE
• It refers to the amount of capital invested, number of 
people employed and the volume of production or mass 
production.
• Based on size, industries can be classified into :
• small scale and large scale industries.
• Small scale industries are industries where the 
products are manufactured by hand, by the artisans.
• Large scale industries are industries which produce 
large volumes of products.
• Investment of capital is higher and the technology used 
is superior in large scale industries.
