Old Bridge Chemicals, Madison Industries and Madison Chemicals were established in 1962. Collectively we are major suppliers of copper and zinc compounds and solutions, serving a variety of chemical-related industries while focusing on a select number of products.
We are the largest manufacturer of Copper Sulfate in the United States. In addition, we are a major supplier of Copper Carbonate, Zinc Sulfate, Zinc Chloride, Zinc Orthophosphate, and Phosphoric Acid, as well as other chemical products containing copper and zinc. Our basic strategy is to focus our expertise on a handful of products while producing a variety of grades. This allows us to provide the excellent service and consistent quality our customers deserve. We are a manufacturer, not a broker or distributor. We proudly put the American flag on every package we manufacture and sell.
The proximity to major transportation hubs allows us to ship our products worldwide in a quick and cost effective manner. All of our products are manufactured at our plant in Old Bridge, New Jersey, USA.
