d 料咩時間到才可以趕得及 7 月尾出貨呢
When should the raw material be arrived latest to catch the shipment during end July ?
Seemed not quite reasonable or not understandable in your original Chinese text, above just translated from your wordings.
d料 = 原料 (即要有原料才可 on production開工?).
估計這句的原意是要對方答你: 一個日子?
例 - 答: We can catch the end July shipment if we can received the raw material on or before 15th July.
似乎很煩, 但只希望能答得準確.
