中译英 高分求助~

As the customer has not decided when to replace/change the supplier, they require us to complete/fulfill all the ordered quantities before such replacement/change.
While we are discussing the details with the customer, please confirm the following (three aspects):
1. The MOQ for purchasing the raw materials of this product;
2. The purchased raw materials are sufficient/enough for producing/manufacturing how many (pieces of) such products;
3. The L/T for purchasing the raw materials.

As customer had no idea when to change the suplier so we have to finish all present orders as he told,and we're negotiating with him.Please help confirm below 3 points:
1.The MOQ of raw material we need to buy?
2.The quantity of product we can produce with the raw material we will purchase?
3.L/T for raw material?
