Narrative:

I was sent down-line to ZZZ line to work on tooling. After completed the tooling project; around I saw a lot of unserviceable parts; so I boxed them up and returned them back to ZZZ1. I had also prepped an aed for hazmat shipment. But I don't remember noticing the fuel valve while I was boxing the other unserviceable parts. Until today I discovered from my co-worker that I had sent the valve.
