FactoryRegistry lists 1,715 facilities whose primary industry classification is one of the 2 industries above. This is a list by industry, not a list of makers: Census reports that establishments in these industries produced potassium chloride, potassium sulfate, and potassic fertilizers, 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 2 US manufacturing industries in the 2022 Economic Census, as the most specific line those industries reported. At least 9 establishments reported producing it; the count for 1 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.
NAPCS collection code 2034635000. Source for the product line, the establishment counts and the shares: U.S. Census Bureau, 2022 Economic Census (ECNNAPCSIND2022). Federal source data is public domain. Facility records are compiled separately by FactoryRegistry and carry their own sources.
