What Grand Rapids Defense Buyers Should Know
L3Harris West Michigan programs need ITAR-controlled shops
Electronic warfare and communication system components require pursuing ITAR registration suppliers with access controls. Verify before sending drawings.
Automotive-to-defense crossover requires spec awareness
West Michigan shops transitioning from automotive to defense must understand MIL-spec documentation and ITAR requirements. Training matters.
Lake Michigan winter weather delays freight
Lake-effect snow from November through March can shut down US-131 and I-96. Add weather buffer to delivery schedules.
