MASTER INTERNATIONAL CORPORATION

Master International Corp specializes in the design, manufacturing, and supply of mission-critical electrical and electronic components for defense and industrial applications. Their core capabilities center on relay and industrial control systems, current-carrying wiring devices, electronic connectors, and specialized lighting assemblies—products essential to military avionics, vehicle systems, and command-and-control infrastructure. The contractor demonstrates deep technical proficiency in high-voltage switching, magnetic contactors, hybrid relays, and precision contact assemblies, often delivering custom-engineered solutions requiring stringent environmental and electromagnetic compatibility standards. Their ability to produce ruggedized components for harsh operational environments—such as centrifugal fans for thermal management and indicator lights for cockpit interfaces—positions them as a trusted supplier of durable, field-deployable hardware. The company maintains a consistent and exclusive relationship with the Department of Defense, supplying mission-essential components across multiple platforms including ground vehicles, naval systems, and aerospace equipment. All recent awards reflect direct support to DoD procurement cycles for spare parts, replacement assemblies, and subsystems requiring strict military specification compliance. Industry focus is firmly rooted in electrical component manufacturing, with primary emphasis on relay systems (NAICS 335314), wiring devices (335931), and electronic connectors (334417). These categories represent the backbone of power distribution and signal integrity in defense electronics, indicating a niche specialization in low-volume, high-reliability production rather than consumer-grade components. Master International Corp operates as a small business entity headquartered in Phoenix, Arizona, with no federal certifications on record. Their market positioning is that of a specialized Tier 2 supplier, leveraging precision manufacturing capabilities to meet the exacting demands of defense and industrial end-users without reliance on formal socioeconomic designations.
