There are no extra shipping fees on ammo with UPS. They do not charge a Haz-Mat fee. I have done it a dozen times. I tell them exactly what is in the box. And on the sides of the box I write ORM-D and draw a rectangle around those letters. It cannot be shipped by AIR just UPS GROUND.
The rules are made by D.O.T. and not UPS but UPS follows those rules. http://www.ups.com/content/us/en/resources/ship/packaging/guidelines/firearms.html
SOME UPS stores will not accept ammo to ship. It is best to go to the closest MAIN shipping building for your area.
UPS does not charge haz-mat fee on ready made ammo.
They do charge if it is powder or primers , but make a loaded round with it and no fee.
Some dealers charge haz-mat fee if they want on ammo.
Some UPS clerks do not know the law or their companies policy and make stuff up.
You may draw a picture of the orm-d sticker , UPS also has these stickers for you to use.
Some UPS clerks don't know this either.
If you have trouble with a UPS clerk have them call the main UPS office and contact their Haz-mat division and they will set them straight.
You can only send ammo from a UPS central hub.
Not some UPS booth in staples or the mall.
You need the sticker or a drawing on the package.
Nothing over 50 cal
This is how it is.
