People who change resources into an output that tends to be more desirable than the resources were in their previous form (e.g., when people produce french fries, consumers are more inclined to buy them than the oil, salt, and potatoes individually).
Companies, often state organizations, which own oil wells and the crude which flows from them. This category includes a large number of private enterprises. Integrated oil companies and specialists called independent producers develop much of the world's crude supply. But, as a matter of custom, the industry tends to think not of them but of oil exporting nations when speaking of producers. Other names, such as equity holders, leaseholders, or even equity producers, distinguish these private, commercial organizations. They need a separate category because they must buy the oil they develop, through lease fees, royalties, cash, production sharing, or other arrangements, from whoever has sovereign right to it.
Under Part I of the Consumer Protection Act 1987, strict liability for products applies principally to a producer. A producer is considered in law to be the manufacturer, a trader who holds himself out to be the manufacturer (e.g. an own-brander) or the first importer of the product into the EU. Liability under the Act also applies to suppliers who do not identify any of the foregoing within a reasonable time of being asked to do so.
