New data from China’s customs authorities show that exports of dysprosium rose markedly in December. A total of 4,120 kilograms were shipped abroad, compared with only 995 kilograms in the previous month. Japan was the leading destination, followed by South Korea and Malaysia.
Looking at the full year 2025, however, exports of this rare earth element fell by 35 percent. The decline primarily affected Japan, which received 95 percent less material than in 2024. South Korea, by contrast, more than tripled its import volume.

Exports of terbium continued their downward trend. After 4,045 kilograms in November, China delivered only 2,123 kilograms to foreign customers in December. Japan, followed by South Korea and Germany at a considerable distance, was the most important destination country. For the year as a whole, terbium exports also declined by 38 percent, an even steeper decline than for dysprosium.
