All products manufactured by Zhen Ding were 100% compliant with the requirements RoHS, IEC 62474, and the company’s "Procedure for Management of Controlled Substances of Product and Material" and those products account for 100% of the Company’s revenue.
Since 2008, production sites of Zhen Ding have passed the hazardous substance management system certification (IECQ QC080000). The objective of our hazardous substance control is "reducing or avoiding the use of hazardous substances to meet regulatory and customer requirements". We control the use of hazardous substances by following the 5 Nos principle of no designing, no purchasing, no introducing, no manufacturing, and no releasing hazardous substances. Testing devices such as X-ray fluorescence (XRF) spectrometer, inductively coupled plasma (ICP), gas chromatography–mass spectrometry (GC-MS), and ultraviolet–visible spectroscopy or ultraviolet–visible spectrophotometry UV-VIS are used to conduct scheduled tests in order to strengthen the management of hazardous substances in raw materials and products. Meanwhile, in compliance with customer requirements and regulatory requirements concerning applicable hazardous substances, we establish target indicators that need to be met when shipping out products, and constantly monitor the status of these indicators. In addition, we also establish a Green Product organization and established a "Green Product Management Platform" to continuously promote the management of hazardous substances.
