My wife's work refuses to use them for this purpose alone, as they have their own broker. Also, UPS's cut off dollar amount for not paying any brokerage fees is $20. Anything above that and you are screwed per se.
I would not extrapolate to US deliveries what happens in Canada. UPS has a bad reputation among Canadians for their charges surrounding customs clearance in Canada; I have read quite a few horror stories online and assume them to be based in fact.
I was responding specifically to the situation with incoming shipments to the USA, which in my experience were fine. If I recall correctly, the customs brokerage fees were already bundled into the shipping charges I paid, so there was no separate customs clearance charge for shipments I received.
