I was assigned to Aircraft X. I went to get a tool box but it was already taken out. We loaded the flight. I held the freight Hazmat box because we did not have 15 bags. The mail did not show up. I was trying to lock the flight out to get it pushed out on time. I remarked the Hazmat as OTH; but I forgot to remark the mail as NSH. These kind of mistakes can happen when you have to load a flight in less 15 minutes.
Airline ground personnel reported Hazmat documentation error occurred due to insufficient time allowed to properly load and close out flight.
