A different lens on India's industries — grouped by the raw material or resource that drives them.
Beyond classifying industries by size (large/small-scale) or ownership (public/private), a useful geographic lens groups industries by their primary input resource — since this largely determines where an industry locates and how vulnerable it is to resource availability shifts.
Industries using agricultural produce as raw material: cotton and jute textiles, sugar, edible oil, and food processing. These tend to locate near agricultural production zones to minimise the cost of transporting bulky, often perishable raw material.
Industries built around mineral extraction and processing: iron and steel, cement, and aluminium. These are typically located near mineral deposits (e.g., the Chotanagpur belt for iron and steel) due to the high cost of transporting bulky ore.
Industries using forest produce: paper and pulp, timber and plywood, lac, and other non-timber forest products — concentrated near forested regions, though environmental regulation increasingly shapes where and how much extraction is permitted.
A distinct sub-category of mineral-based industry built specifically around energy minerals: petrochemicals (near refineries) and thermal power generation (near coal fields, given the cost of transporting coal over long distances).
Unlike the above, some industries are driven primarily by availability of skilled or cost-competitive labour rather than a physical raw material — IT/ITeS, textiles' finishing/garment stages, and other labour-intensive manufacturing, which can locate more flexibly near labour pools and infrastructure rather than a specific resource deposit.
