Our Values

These values were established and solidified through various sharing sessions over the years, and are the culmination of values which we found to live within our people. 

They act as a method of ‘self-governance’, inspiring employees to align their own actions around a common set of principles regardless of borders and ethnic backgrounds.

Through Sumida Academy we provide a constant reminder of these values so they are instilled into our daily work ethic and so that we live our values.

Conflict Minerals Statement

Reflecting the Code of Conduct in “Sumida Business Principles”, we never use conflict minerals that originate in conflict-affected and neighboring areas for the purpose of cutting the humanitarian crisis such as violence, plunder, abuse and child labor by rooting out sources of funding for the ongoing conflict. Sumida Group procure conflict-free minerals for fulfilling corporate social responsibilities of Sumida Group.

Profits from the trading of minerals mined such as tin, gold, tantalum and tungsten in the Democratic Republic of Congo and its neighboring nations have been used to finance armed rebel groups, allowing them to continue fighting and encouraging ongoing inhumane acts, such as mining using forced or child labor. Aiming to bring conflict to an end by cutting off the source of funds for armed group, the U.S. Dodd-Frank Wall Street Reform and Consumer Protection Act was signed into law on July 21, 2010. Section 1502 of this act has mandated that companies registered with the Securities and Exchange Commission must publicly disclose their use of conflict minerals. With the cooperation of suppliers, Sumida Group are determining if any such minerals are contained in existing products and establishing a framework to ensure they are not used in new products. As much details as possible of the Sumida Group’s survey (based on the EICC/GeSIDD template) will be disclosed to customers.

Cadmium: 0.01% wt (max. concentration by weight in homogenous materials)
Mercury: 0.1% wt (max. concentration by weight in homogenous materials)
Hexavalent Chromium: 0.1% wt (max. concentration by weight in homogenous materials)
Lead: 0.1% wt (max. concentration by weight in homogenous materials)
Polybrominated biphenyls (PBB): 0.1% wt (max. concentration by weight in homogenous materials)

Certificate of Compliance - RoHS Declaration
SUMIDA Prohibition & Declaration of Substances (SUMIDA EUROPE GmbH & SUMIDA COMPONENTS & MODULES GmbH)


  1. What is the best preservation condition for keeping the RoHS compliant product?
    The preservation environment must be controlled to prevent any caustic substance/effect (including airborne) or dew condensation. The expected ambient temperature should be between 5 and 40° C and relative humidity of 20 to 70%.
  2. Are there any differences between Lead Free products and RoHS compliant products?
    Previously listed "lead free" products were studied and considered compliant, in regards to lead content only for lead-free soldering of terminal connection, case, and hoop. At that time, Cadmium, Mercury, Hexavalent chromium, PBB, and PBDE were not studied. So we can not say "lead free = RoHS compliance". In fact, only a few products reviewed their constituents on the six hazardous substances and eliminate them.
  3. When is the expected date of full conversion of Sumida products to RoHS compliant products?
    After January, 2006, SUMIDA only manufacture RoHS compliant products.
    NOTE: Regarding customized products, we will follow the date of specific customer requirements.
  4. How can customer distinguish the RoHS compliant devices from the non-compliant parts?
    SUMIDA standard products (S-074-XXXX specification sheets): A RoHS logo will be added on specification and on the reels & boxes.
    Customized products: We basically change the part name in conversion from lead free to RoHS compliance. Actually, we follow the customer’s requirement.
  5. Can customer order those non-compliant RoHS products?
    SUMIDA does not manufacture non-RoHS compliant standard products (S-074-XXXX) after January, 2006. Regarding customized products, when non-RoHS compliant products are needed by all means with products having you place an order conventionally, we shift it to customized products handling and the present production is possible. It becomes the other controlled production as non-standard products.
