Human Factors
We were aircraft on ground in ZZZ for a slide. [Tracking system] spreadsheet this unit was not Hazmat. When told unit had Hazmat stickers on it. When off other units that was have waivers to be able ship. All the information I had to go off stated the unit was not Hazmat. Even the documentation for the unit didn't state it was Hazmat. Asked planning about their list of slides deemed non-Hazmat and they were unable to find. We do have several parts were the interchangeable part is not Hazmat. As the system told me that the slide was not Hazmat it was faster to send our unit then to get a unit from ZZZ1 by several hours.  Cause: Due to incorrect info in system items was shipped on [passenger] flight when it should not have been.Suggestions: Always have copy of pick list from [software] with no Hazmat statement.
Maintenance Technician reported Hazmat aircraft part was incorrectly shipped as Non-Hazmat.
