FactoryRegistry lists 1,355 facilities whose primary industry classification is one of the 1 industry above. This is a list by industry, not a list of makers: Census reports that establishments in these industries produced potassium hydroxide (caustic potash) liquid (including liquid later converted to dry or solid) (Basis - 88-92%, KOH), 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 1 US manufacturing industry in the 2022 Economic Census, as the most specific line that industry reported, where 16 establishments reported producing it.
