Approach to Quality ~ IATF16949 ~

IATF 16949 is an international standard for a quality management system specialized in the automotive industry.

It establishes, based on the ISO 9001, the rules and regulations related not only to the specific requirements in the automotive industry, but also to the customer specific requirements, in order to aim at "defect prevention", "reduction of the variation and waste in the supply chain" and "continuous improvement".

Many vehicle manufacturers in the world introduce this standard for certification systems in the global automotive supply chain.
At LEJ, since we were certified the ISO/TS 16949, the predecessor of the IATF 16949 in September, 2011, our certification has been maintained, and we achieved the IATF 16949 certification in January, 2018.

Centering on this quality management system, we have realized stable quality by the reliable process management.
We provide our lithium-ion batteries for vehicles as well as those for industrial use with "reliability" and "satisfaction" at the quality level fulfilling the demanding requirements in the automotive industry.
