shipping an accumulator ball

[elevensecgn]

Can an accum ball be shipped USPS priority mail or is it considered hazardous material due to being pressurized? If so I assume it would have to go UPS ground??
Thanks

UPS is probably a better choice anyhow.

USPS if something is lost, you have to wait 30 days to make a claim. You have to pay for a lot of the paperwork involved. Their tracking system sucks, etc. No need to ask me how I know.
