Industry Certifications & Policies

Ever since WIN Enterprises was established we've followed the physicians' first rule: do no harm. In mid-2000's we began adopting manufacturing guidelines to help protect the earth. Then in 2012, we began formally applying for certification of the world-leading management systems. We passed third-party certification for all systems and obtained relevant certificates, including TUV, RoHS, and IECQ. In addition we developed the below written policy for dealing with Conflict Minerals and responsible materials sourcing.
