Employees close a massive security door inside inside the storage room of Tradium, a company specialised in trading rare earths, in Frankfurt am Main, western Germany, on November 4, 2025. Tradium keeps thousands of barrels of the precious materials -- almost all from China, the world's biggest producer. The materials in the bunker, such as dysprosium, terbium and neodymium, are essential for the manufacture of crucial modern technology including smartphones, electric cars and wind turbines. Tradium, which employs fewer than 40 people, expects to reach a turnover of 300 million euros ($346 million) this year.
