A machine builder specs a standard disc magnet for a rotary position sensor. On the bench, it performs exactly as expected. Then the assembly moves into a production machine, where a nearby drive adds electrical noise, the enclosure traps heat, and the sensor starts reporting drift under load. The magnet was not defective, but it

What “Permanent” Actually Means Under Temperature When a magnet is called “permanent,” it’s easy to assume that means its performance stays the same no matter what the application throws at it. In practice, that’s not what “permanent” guarantees. A permanent magnet retains its magnetization without needing an external field or power source. What it does

Strontium carbonate shortages and tightening environmental regulations are pushing ferrite magnet costs higher. Here’s what’s driving the change, why it’s likely to persist, and how to protect your supply chain. Ferrite magnets (also known as ceramic magnets) have long been considered the most stable, cost-effective option in the permanent magnet landscape. But over the past
What’s happening Under the U.S. government’s 2024 Section 301 tariff modifications, permanent magnets of Chinese origin will carry an additional 25% duty starting January 1, 2026. This increase was finalized by the Office of the U.S. Trade Representative (USTR) and is part of a broader set of strategic-sector tariffs. Government source: For the official explanation

Published: October 30, 2025 Executive summary China and the U.S. reached a joint arrangement in Kuala Lumpur trade consultations. As part of that package, China will suspend for one year the October 9, 2025 export controls that would have added holmium (and several other rare earths) to the dual‑use control list. The April 4, 2025
Published October 21 *Please see updated blog published 10/30/25 Executive summary China’s Ministry of Commerce (MOFCOM) and General Administration of Customs (GACC) issued Announcement No. 57 (2025), expanding dual‑use export controls to include holmium‑containing items (and other heavy rare earths). Beginning November 8, 2025, 13 additional NdFeB grades that contain holmium will require an export
Preface: The Export-Control Challenge On April 4, 2025, China began requiring an export license for any magnet containing the heavy rare earth elements dysprosium (Dy), terbium (Tb), or gadolinium (Gd). The license process can add weeks of paperwork, inspections, and uncertainty, which is particularly painful for manufacturers that rely on just-in-time deliveries. Read more about

Tariff Reductions Following Temporary Truce On May 12, 2025, the U.S. and China agreed to a 90-day trade truce, which resulted in a reduction of U.S. tariffs on Chinese goods, including those for permanent magnets. The total tariff on all Chinese magnets was lowered to 30%, comprising: A 20% “fentanyl tariff” (10% imposed on February

Recent changes in Chinese export policy are directly impacting the global supply of rare earth magnets, particularly Neodymium-Iron-Boron (NdFeB) and Samarium-Cobalt (SmCo) magnets and assemblies. China has implemented new export controls on several rare earth elements, including Dysprosium and Terbium — essential components in many high-performance magnet applications. These controls are designed to limit the
