The RoHS directive,REACH regulation,and other laws and regulations related to the management of
environmentally hazardous substances come into effect. When developing products,the global
enviromental load must be considered. ROHM pursues green procurement and endeavors to increase
the detection accuracy of chemicals contained in parts and procured materials while at the same time
placing great importance on the internal chemical management system that was built to ensure that no
prohibited substances are procured,used,or shipped in order to provide a steady supply of worry-free
products.
