I have only ordered from Pickering (and Skinner). Pickering, I think, sends trucks across and has them all inspected at once, so they then enter the US shipping system. The order from Skinner came through both postal services without a problem.
I do know folks in Kentucky who would drive to Ontario to pick up rather massive orders from the company that has become Palatine.
The dry out nightmares seem to happen more on roses from the other hemisphere.

I've never had an inspection problem with roses ordered from Canada. Those companies have all the paperwork prepared ahead of time and have licenses to ship to the U.S.
You don't need to worry.

I haven't had a problem with either Pickering or Palatine. They send a notice when they are shipped, the customs issues are handled, and they have arrived when expected.

I had no problem with Palatine. They shipped exactly as expected and were in very good shape on arrival. You'll be so happy you ordered when you see the size of the roses they send. Hortico sent very small roses but there were no problems with shipping.

In fact, the only roses that did dry out in shipping were actually from Jackson and Perkins. It wasn't their fault, the post office lost track of them for a while and then the box showed up in Texas for some reason. I think it took two weeks to get them and they were very dry by then. JP had already sent me replacements by the time they arrived. I went ahead and soaked and planted them anyway and all the roses did well. So even if something does get stuck in customs I doubt it would kill a healthy bareroot rose. And I think any company would offer replacements if it did happen.

I never had any problems as to shipping roses from Canada. I ordered from all three companies that ship to the US. Hortico is the least reliable but never because some issues at the border but because they didn't have the rose that they thought they did, etc. etc. Pickering uses FedEx and the roses are here in a week, never got a dried out plant from them. Palatine uses UPS and their roses were here in 4 days; their plants are super quality. Shipping from California usually takes more time to the east coast then shipping from Canada.

What about the shipping costs? Brandy

Brandy, the shipping costs from Canada to NC are probably less than you would pay to certain suppliers on the US west coast.

I second veelakin's statement.

My Palatine order was all inspected and ready to go before it left home. No wait whatsoever.

If you order potted plants from any vendor with just a few plants you can end up paying more than for a lot of bare roots shipped from Canada.
