About Us

Who is Sumitronics?

With over 30 years of experience from distribution and procurement to manufacturing

Sumitronics is a wholly owned subsidiary of Sumitomo Corporation, an international conglomerate. Back in 1988, Sumitronics was initially established in Singapore as a full-fledged trading company specializing in electronic components. Later, our business expanded into the ASEAN countries, such as Thailand, Indonesia, The Philippines, and Vietnam, as well as Hong Kong, China, and North America. We have evolved into an EMS company that handles the procurement of materials while operating our own plants. We use our over twenty-year experience to flexibly coordinate EMS from logistics and procurement to manufacturing.
