We are audited to QS9000, but have an ISO 9001 certificate, because we do not own any manufacturing. We use all contracted manufacturing sites. Some of the products we design are required by the customer to be QS compliant. So, we use a QS certified manufacturing facility. However, some of the products we design or not required to be QS compliant. So, can we still use a QS certified manufacturing facility? Or, does this affect their certificate, beacuse they would be manufacturing a design that is only ISO, not QS?
