请高手帮忙确认下面翻译的有没有语法或者时态问题！谢谢了！！！

这些盒子会先暂时存放在仓库里面，然后再由小红负责退回3楼wafer仓库。
These boxes will be stored temporarily in the warehouse and they will be returned to the warehouse on the third floor by Xiaohong .

另外确认的结果是这些盒子上面的标签在退回3楼仓库之前就已经全部被撕掉了。
Additionally, the confirmation result is that all the labels attached to those boxes have been removed (torn off ) before being sent back to the warehouse on the third floor.

be stored，被动式你的过去分词呢？
then returned
returned to the wafer warehoure located at 3F by Xiaohong
and the comfirmation wheather the labels on the boxes are removed will be done finally.用remove，英语通常不会把具体动作说出来，而用抽象行为。你非得“撕掉”标签么？刮掉就不行？

最後————————

“全部撕掉了”就可以，不需要“被”！！！！！！！

都是过去时态，then，是定语从句的语句。
