Dow Chemical Company — chemical industry Dow Chemical plant in South Charleston, West Virginia.

The chemical industry relies on a diverse array of raw materials to produce its vast range of products. These materials are often categorized by their origin and chemical composition, serving as the fundamental building blocks for industrial synthesis.1

Primary Raw Materials

The most significant raw materials for the chemical industry include:

Fossil Fuels: Coal, natural gas, and petroleum are essential, providing the hydrocarbons necessary for a wide variety of organic chemicals.21
Common Inorganic Substances: Air, water, salt, limestone, and sulfur are foundational inputs for many chemical processes.1
Specialized Materials: Depending on the specific product, industries may also require phosphates and fluorspar.1

Feedstocks and Processing

In the petrochemical sector, raw materials are often referred to as feedstocks. These are frequently classified into three groups: olefins (such as ethylene and propylene), aromatics (such as benzene and toluene), and synthesis gas used to produce ammonia and methanol.2

Because the chemical industry is highly interconnected, many of its products serve as raw materials for further processing, meaning the industry is effectively its own best customer.1
