In May 1995, KITZ METAL WORKS became the first manufacturer of brass bars in Japan to acquire "ISO9001" certification. "ISO 9001" examines the quality assurance system of overall corporate activities, from order receiving to shipping and after-sale service. At our factories, we run thorough quality control with our unique quality control system from raw materials through all our manufacturing processes and to shipping. With the launching of the new JIS mark system, KITZ METAL WORKS has acquired the new JIS mark certification given for satisfying JIS standards and producing products that comply with JIS.
