Delete Duplications When Importing - vba

Question

I'm doing this code for the company where I work as a internship. I did some part of it with the help of people from this forum and others but the code is big and I cannot find a place or the piece of code needed to do what I asked for, and that fits my code I'm newbie by the way.
So I will explain the code IT will import from a target excel file and then paste in my main file, after that it will search in the main file for the data that is present in the column A and then copy the information that is linked to the names and paste it in the import sheet called (Status) so I wanted to put a delete duplications before searching the information in the main file.
Sorry for the Big code. Forgot to mentioned the files come duplicated from the source file but I cannot change the source file, probably is easier if the import doesn't take duplicated rows ?

Using the VBA side of Range.RemoveDuplicates instead of manually just doing Remove Duplicates from the Data ribbon.
