Sumitomo Wiring Systems holds a Suppliers Meeting every year to explain our procurement policies and report our business activities to our suppliers.
We prepared "Sumitomo Wring Systems Group Contacts for Compliance Reporting" to establish a system where suppliers can consult with the Compliance Secretariat in the General Affairs Department apart from Material Procurement Departments.

While expanding our business operations worldwide, SWS is endeavoring to realize “globally optimal procurement,” which is to purchase the parts, materials and equipment that are the best in terms of quality, quantity and cost from the global market.
In addition to global optimal procurement, we will strive to live together in mutual prosperity with local communities at overseas manufacturing sites through local procurement.
