FactoryRegistry lists 28,085 facilities whose primary industry classification is one of the 28 industries above. This is a list by industry, not a list of makers: Census reports that establishments in these industries produced Other electronic and electrical 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.

The U.S. Census Bureau recorded this product line in 28 US manufacturing industries in the 2022 Economic Census, as the most specific line those industries reported. At least 954 establishments reported producing it; the count for 5 of those industries was withheld.

These are counts of establishments by industry: the Economic Census publishes them as industry totals and never as a list of plants.
