CHINA’S exports of natural graphite, a material used in electric vehicle batteries, plummeted in December after the government imposed controls at the start of the month. Overseas sales plunged 91% month on month to 3,973 tons, according to Chinese customs data, after a rush to buy ahead of the deadline saw them surge to more than 45,000 tons in November. Exports had averaged about 17,000 tons a month in the year through October. The export restrictions apply to materials deemed highly sensitive as so-called dual-use items, a reference to military applications. The curbs were announced just days after the United States stepped up efforts to keep advanced semiconductor chips out of China. Exports of synthetic graphite, which aren’t subject to the curbs, fell 28% to 39,763 tons last month. The commerce ministry flagged in the middle of December that some graphite export applications had been approved. Sales should slow notably from December to the Lunar New Year holidays, which fall in mid-February this year, as government approvals take quite a long time, Shanghai Metals Market said last week, citing its survey of domestic producers. Overseas demand also usually weakens toward the end of the year, and that was particularly the case after purchases ramped up in November, it said. Chinese shipments of two other critical minerals — germanium and gallium — also continue to be affected by separate controls imposed earlier in the year on national security grounds. Germanium exports jumped more than four times to 3.36 tons in December from the month before, while overseas sales of gallium surged to 7.03 tons from 1.53 tons. The minerals are used to make parts for chips, telecommunications equipment and electric vehicles. Some 94 tons of gallium and 44 tons of germanium were exported by China in 2022. (SD-Agencies) |
