Air Carrier Lead Crew Chef reported that a Maintenance Logistics Specialist discovered a Hazmat company parcel marked for shipping which contained incorrect Hazmat documents and missing required Hazmat Labels.

Narrative

Material Logistic Specialist on duty in the ZZZ Warehouse Shipping Department was preparing material for the Load Device 3 can to ship to Company Maintenance Base. Material Logistic Specialist came across Airways Bill Parcel which is in a hard sided case. The paperwork on the outside of the box was a hand written note that said send to [shop]. This shop is a Company shop. The box had the address; Name and Vendor Number on the repair order. This is not the appropriate paperwork to ship something. When Material Logistic Specialist opened the case she found a repair order # XXXXXXX that was shipped from ZZZ1 on Airway Bill XXX-XXXXXXXX to ZZZ. There was Hazmat paperwork with the shipment that had been generated. None of the repair order paperwork had a Hazardous Materials sticker attached. When I did some research I discovered that this cleared customs on Date and brought to the base by freight truck on that day [who] took the shipment to ZZZ Warehouse Receiving Dept where it would be sorted to where it would go or be received into inventory.
