A raw material or feedstock is the basic material from which a good product is manufactured or made, frequently used with an extended meaning. For example, the term is used to denote material that came from nature and is in an unprocessed or minimally processed state; e.g., raw latex, iron ore, logs, crude oil, air or seawater. The use of raw material by non-human species includes twigs and found objects as used by birds to make nests.
