This table presents detailed information on the quantities and values of ammonium paratungstate exported from the United States to various countries and localities. Ammonium paratungstate is a critical intermediate in the production of tungsten metal and its compounds, which are essential for manufacturing hard metals, electronics, and military applications. Tracking export data by destination helps to understand global demand patterns, trade relationships, and the economic impact of the U.S. tungsten industry on international markets.
Analysis of the data reveals a significant increase in total exports from 36 metric tons of tungsten content valued at $333,000 in 2020 to 116 metric tons valued at $915,000 in 2021. Notably, Germany emerged as a major new destination in 2021, receiving 55 metric tons valued at $486,000, whereas it had no recorded exports the previous year. Brazil also experienced a substantial rise, from negligible exports in 2020 to 14 metric tons worth $125,000 in 2021. Conversely, exports to South Africa ceased entirely in 2021 after 22 metric tons valued at $198,000 in 2020. Mexico saw a decrease in both volume and value, dropping from 12 metric tons ($111,000) to 8 metric tons ($70,000). The United Kingdom and Switzerland appeared as new importers in 2021, with 28 and 5 metric tons respectively. These shifts indicate evolving trade dynamics and possibly changing industrial demands or supply chain adjustments in the global tungsten market.
