Rare-Earth Metals, Scandium & Yttrium

Rare-earth metals — including lanthanum (2805300005), cerium (2805300010), neodymium (2805300020), scandium, yttrium, and mixed rare-earth alloys — are critical inputs for permanent magnets, phosphors, catalysts, and advanced defense systems. Imports from China, the dominant global producer, are subject to Section 301 tariffs, making supplier diversification a strategic priority for US manufacturers. South Korea and Canada are secondary sources, with the United Kingdom and Turkey rounding out the top five. The heading covers both individual separated elements and intermixed or interalloyed forms, so precise product characterization is essential for correct 10-digit classification.
