FactoryRegistry lists 20,982 facilities whose primary industry classification is one of the 7 industries above. This is a list by industry, not a list of makers: Census reports that establishments in these industries produced Clay, glass, cement, and other nonmetallic minerals products contract manufacturing services, performed using materials owned by others (i.e., the customer), in the shares shown above, and does not say which establishments. Where a plant’s own website or a federal registry names what that plant makes, it appears on the plant’s own page with the source named.
