Atlas Vac suppliers are critical to our performance. Atlas Vac selects its suppliers based on a strategic set of criteria focused on capability, geography, reliabilty, and cost. It is our policy to first consider US based suppliers where possible and then US allies. All suppliers are subject to Atlas Vac site review to assure performance capability and alignment with Atlas Vac needs. Suppliers are paid on net 30 terms to enable a strong supplier base responsive to our delivery requirements. All purchases require a PO or purchase card authorization. Any materials received without matching a PO or purchase card will be subject to return to point of origin at cost of supplier.
