During the 1990s and 2010s, when China Tungsten Online initially produced and operated tungsten products, among all tungsten compounds and tungsten oxides, ammonium metatungstate was the only product that did not require an export license. The reason for this was that the export volume of ammonium metatungstate was small, and its uses were mostly for catalysts, fuels, and other purposes. Almost all customers were concentrated in one or two Japanese companies, while there were only a few domestic exporters, At that time, there was only one enterprise producing ammonium metatungstate using extraction method, namely Fujian Sheng Powder Metallurgy Plant. Afterwards, the export control of ammonium metatungstate was implemented under the same customs supervision conditions as that of ammonium paratungstate, and an export licensing system approved by the Ministry of Commerce was adopted.
