=Introduction=
A raw material, also known as a feedstock, unprocessed material, or primary commodity, is a basic material that is used to produce goods, finished products, energy, or intermediate materials that are feedstock for future finished products. As feedstock, the term connotes these materials are bottleneck assets and are required to produce other products.

The term raw material denotes materials in unprocessed or minimally processed states; e.g., [[raw latex]], [[crude oil]], [[cotton]], [[coal]], [[raw biomass]], [[iron ore]], [[air]], [[logs]], [[water]], or "any product of agriculture, forestry, fishing or mineral in its natural form or which has undergone the transformation required to prepare it for international marketing in substantial volumes". The term secondary raw material denotes waste material which has been recycled and injected back into use as productive material.
