Not Hazmat but there is a symbol that I print that goes on the box indicating small arms ammo. I'll look and see if I can put hands on it and post here.

Try this

Thank you Keith

Certainly.

I could be wrong but I believe UPS no longer wants you to ID as Ammo. They want it labeled with the black and white Diamond..
This is what I have been doing, please see the picture.
I bought a roll off of Amazon as I recall.

I think UPS will only accept the shipment of ammo if you have a prepaid shipping label from the party you are shipping to. That is the only way FedEx will accept it, and I just shipped UPS to Precision for some testing and I had to call them an purchase a shipping label from them, then UPS would accept the package, properly marked with the black diamond. And USPS will not accept under any conditions. At least that is what I have been told.

All the above entirely possible, I haven't shipped any in many months. Recommend a phone call before shipping.

Jim told me "you can't ship ammo to me so have RST ship me some." What a PIA.
