Steel

Raw materials are substances that are used in the production of goods and services. They are typically unprocessed or minimally processed, and can be classified into three main types based on their origin:
Plant/tree-based: Materials like wood, resin, latex, fruits, vegetables, and flowers
Animal-based: Materials like leather, meat, bones, milk, wool, and silk
Mining-based: Materials like minerals, metals, crude oil, and coal
Raw materials are a vital part of the global economy and international trade, and are bought and sold on commodities exchanges around the world. They can also be classified by the nature of their extraction, such as mined raw materials, plant-based raw materials, and animal-based raw materials.
