U.S. imports of permanent magnets made of metal (HS 850511) totaled $36.6M in April 2026, traded with 49 countries.
Last updated: April 2026 dataSintered neodymium-iron-boron (NdFeB) magnets — classified under 8505110070 — are the highest-performance and most commercially significant product within this heading, serving as critical inputs for EV motors, wind turbine generators, robotics, and defense systems. China dominates global NdFeB production and leads US import supply by a wide margin, creating concentrated supply-chain risk that has drawn significant policy attention; goods from China are subject to Section 301 tariffs. The heading also covers alnico (8505110010), ceramic ferrite (8505110030), and sintered samarium-cobalt magnets (8505110050), each with distinct performance-versus-cost trade-offs relevant to motor and sensor designers. Japan and Germany are secondary suppliers, particularly for specialty and high-grade samarium-cobalt types.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Both fall under heading 850511, but at the 10-digit level they are separated: sintered NdFeB magnets are classified under 8505110070, while ceramic (ferrite) permanent magnets are classified under 8505110030. The distinction is based on material composition and manufacturing process — sintered rare-earth alloys versus oxide-based ceramic compounds — and the two lines may carry different Section 301 duty treatment depending on origin.
Unmagnetized blanks intended to become permanent magnets are classifiable here alongside finished magnets, but importers should be prepared to provide technical specifications confirming the material composition and intended magnetization process. CBP may request this documentation to confirm the article is not more appropriately classified as a semi-finished metal product under another chapter. A binding ruling is advisable for novel alloy forms.
