Under ISO9001 international quality management system, WINDAN
established an independent QC Dept. All the products should pass QC
inspection at every stage of production otherwise they will be
rejected and will never arrive to our customers. In addition,
WINDAN provides a one year warranty for all the products.
And for those products we sell which are not produced by ourself,
we have specially and professional QC to check for every order
during the producing till shipment.
