Question

“Manufacturing industries are classified on several bases.” Examine the main bases of classification in favour of the statement.

Hint:

To remember the primary bases of industrial classification, use the acronym S-R-O-O: Size, Raw materials, Output, and Ownership.

Answer 1

Step 1: Introduction to Manufacturing Industries:
Manufacturing involves the physical or chemical transformation of raw organic or inorganic substances into new finished goods. It occurs at various scales depending on technology, capital, and labor. To systematically study, map, and plan industrial development, manufacturing industries are classified on multiple distinct bases.

Step 2: Classification Based on Size (Capital Investment and Workforce):
Size is determined by the amount of capital invested, the number of employees, and the volume of physical production. This divides industries into:
• Cottage or Household Industries: The smallest, most localized form of manufacturing. Artisans use local raw materials, simple manual tools, and family labor to produce goods for local consumption. There is minimal capital outlay and no commercial transport involved. Examples include handloom weaving, pottery, and basket making.
• Small Scale Industries: These utilize power-driven machinery, semi-skilled labor, and local raw materials. Capital investment is higher than household industries, and products are sold beyond local markets. They generate high employment per unit of capital. Examples include garment manufacturing and toy making.
• Large Scale Industries: Characterized by massive capital investment, advanced technology, automated machinery, large-scale employment of skilled workforce, and specialized management systems. These produce massive quantities of standardized goods for national and international markets. Examples include the iron and steel, automobile, and petrochemical industries.

Step 3: Classification Based on Raw Materials Used:
Industries are classified by the nature of the primary inputs they process:
• Agro-based Industries: Process agricultural produce into commercial products. Examples include sugar mills, cotton and jute textiles, tea/coffee processing, and food canning.
• Mineral-based Industries: Use metallic or non-metallic minerals as primary feedstocks. These are further sub-classified into:
• Ferrous mineral-based: Processing iron ore, manganese, etc. (e.g., Iron and Steel industry).
• Non-ferrous mineral-based: Processing copper, aluminum, etc. (e.g., Aluminum smelting).
• Non-metallic mineral-based: Utilizing clay, sand, limestone, etc. (e.g., Cement and glass industries).
• Chemical-based Industries: Utilize natural and synthetic chemical compounds. Examples include petrochemical complexes, chemical fertilizers, plastics, synthetic fibers, and pharmaceuticals.
• Forest-based Industries: Rely on major and minor forest products. Examples include paper and pulp mills, timber and furniture factories, lac, and resin processing.
• Animal-based Industries: Process raw materials derived from livestock. Examples include leather tanneries, woolen textiles, and silk weaving.

Step 4: Classification Based on Output (Product Type):
This is based on whether the output is consumed directly or used as an input for other manufacturing processes:
• Basic Industries: Also known as key industries, these produce raw materials or machines that are vital for running other industries. For example, the Iron and Steel industry is a basic industry because its steel output is essential for manufacturing machinery, railway lines, and industrial equipment.
• Consumer Goods (Non-Basic) Industries: Produce finished goods that are consumed directly by the public. Examples include bread, soap, textiles, paper, and television manufacturing.

Step 5: Classification Based on Ownership:
This categorizes industries based on who controls and manages the enterprise:
• Public Sector: Owned, operated, and funded entirely by the government. Examples in India include SAIL (Steel Authority of India Limited) and BHEL.
• Private Sector: Owned and managed by individual entrepreneurs, families, or private corporations. Examples include TATA Steel and Reliance Industries.
• Joint Sector: Managed jointly by the government and private entities, combining public interest with private sector efficiency.
• Cooperative Sector: Owned and operated by a group of individuals who are themselves the producers of raw materials or consumers. Resources are pooled, and profits/losses are shared proportionally. Examples include Amul dairy and sugar cooperatives in Maharashtra.
