1. Raw Materials - A natural of semifinished god that is used in manufacturing or processing to make some other good. Bauxite is the raw materials (ore) from which aluminum is made; aluminum is turn can be the raw material from which household utensils are manufactured.
2. There is another definitions from the subject area of raw materials distinct from the above mentioned:
Raw materials are products immediately extracted from nature which have undergone a first processing through which they have become marketable and, consequently, a tradable commodity. Raw materials include all energy raw materials (crude oil, natural gas, coal, uranium), metals, semi-metals and industrial minerals (kaolin, graphite, sulfur, salts, phosphates), rocks, water as well as all plant and animal products, whether they come from tropical regions (coffee, jute, tropical timber) or from temperate latitudes (wheat, meat, wool, etc.).
Raw material economy: It comprises all activities which are part of the planned handling of raw materials, i.e. explanation, evaluation, extraction, conversion into a tradable product, trade and forecasting.
"Planned" here means economically useful, ecologically and socially responsible activities.
Resources are all natural material systems which as such are no commodities, but the intactness of which is a basic prerequisite for the continued existence of the earth's chemical and physical equilibrium and, consequently, for the survival of mankind. Resources include: the ozone balance, the CO2 balance, the equilibrium of sea water, the tropical forest, the krill and fish population, etc.
World resource balances are the planned (i.e. ecologically useful and socially responsible) handling of resources. This comprises: the explanation, evaluation, risk assessment and forecasting regarding world resources.

I. Trade intermediates and natural resources
Once international trade in more than final consumer goods is allowed, basic notions of comparative advantage need to be re-examined. We have already discussed the limitations in a multi-commodity word of comparing autarky prices in two countries to predict item-by-item the pattern of trade; generally only correlations can be made except under additional assumptions. With trade in intermediates allowed, the problems in predicting trade in final goods became even greater. As MakKenzie (1945) remarked in one of his classic problem on the Ricardian model, the familiar nineteenth century trade pattern in which Lancashire produced and exported cotton textiles would most probably not have been observed if England had had to grow its own cotton . We shall have occasion both in this section and to revert to this theme: the pattern of trade in final goods may not be readily deducible from the comparison of pre-trade relative prices in these markets.
I.I Middle products (intermediates)
The phrase «middle-products» was used by Sanyal and Jones (1982) to encompass what traditionally are referred to as intermediate goods, goods- in-process, and natural resources which have been extracted and prepared for trade on world markets. The core concept in their model is that of a productive spectrum whereby, at initial stages, natural resources and raw materials are processed and, in the final stages, goods-in-process and intermediate products are locally assembled for national consumption.
International trade, according to this view, takes place in commodities, somewhere in the «middle» of this productive spectrum, freeing up a nation’s input requirements in the final stages of production from its output tradeable middle products at earlier stages.
