/ The challenge
Permanent-magnet motors and actuators are where DFARS 252.225-7052 most often touches a small or midsize defense supplier. Brushless DC and servo motors, stepper motors, torque motors, voice-coil actuators and electromechanical actuators commonly use neodymium-iron-boron (NdFeB) magnets for power density, or samarium-cobalt (SmCo) where high temperature or stability matters. One part number can carry magnets that were made several tiers away from you.
That distance is the problem. A typical chain runs from the mine to separation and refining, then metal and alloy making, then the magnet maker, then the motor or actuator maker, and only then to you. Many supplier declarations describe the magnet maker or the finished motor and stop there. From 1 January 2027 the clause also looks at where the material was mined, refined and separated, so a declaration that covers only the last stages can leave open questions.
Lodeline starts with your part list. We identify which motor and actuator part numbers are likely to contain NdFeB or SmCo magnets, and which suppliers sit behind them. We then prepare stage-specific origin questions for each motor and magnet supplier, follow up with your approval, and review what comes back, matching each document to the stage it actually describes.
You receive an evidence pack per part: each production stage, the facility and country where documented, the document behind every entry, and a plain list of what is still missing and whom to ask. It is built for your quality and contracts teams to review, and for the questions a prime or higher-tier customer may send you.
Lodeline provides supply-chain documentation and analysis, not legal advice or government certification. Applicability, exceptions, and acceptance depend on the contract and the responsible reviewer.
