China and Germany are the leading exporters of ammonium molybdate tetrahydrate, collectively accounting for the majority of global shipments, while the United States, South Korea, and Japan represent the largest importers. Imports by the U.S. and South Korea have shown steady growth over the past two years, coinciding with moderate upward pressure on ammonium molybdate tetrahydrate prices amid tightening supply from key Asian producers.
Ammonium molybdate tetrahydrate is a white to off-white crystalline solid, odorless and non-volatile, with a decomposition temperature above 200 °C (it does not have a defined melting point due to thermal decomposition). It is an inorganic ammonium salt of molybdic acid and serves as a key source of molybdenum in chemical synthesis. Industrially, it is primarily used as a precursor for catalysts—especially in petroleum refining and selective oxidation processes—and as a raw material for producing molybdenum metal, molybdenum oxides, and other molybdenum-based compounds. Its main application areas include catalyst manufacturing, corrosion inhibitors for industrial water treatment systems, and as a nutrient additive in specialty fertilizers and animal feed supplements.
