The charge is 25 or 27 bucks and is a mandated cost to the shipper by the DOT. I don;t know how much, if any, UPS gets to keep. It is a tax in my opinion. I bought powder and primers for years without paying this extortion by the government. Did you know Fedex Ground won't handle Haz-Mat shipments so UPS is the keeper of the only keys.
Handloaders typically make a yearly purchase plus a cushion. You can buy up to 50 pounds IIRC total shipment of powder and primers. And that weight is also mandated.
And of course, once the fearless emperor started in on AWB knowledgeable guys got online and ordered and ordered and back-ordered and those are a prime cause of the powder shortage. I stocked up earlier or I woulda been among them.
This is not a rant because I'm only starting to get wound up on this topic. I believe an executive order directing the DOT to raise Haz-Mat fees would be a real possibility if the resident idiot of 1600 had his way.
