Instead of having a physical delivery, we are requesting a consignment arrangement, to where the supplier will procure raw materials once purchase order is received,
参考译文:我们要求的不是实物交付，而是寄售安排，一旦收到采购订单，供应商将采购原材料。
备注:where为融合性关系副词引导介词宾语从句where=the situation where
to the situation where the supplier will procure raw materials once purchase order is received.
