I have found that FedEx and UPS are different. Had some speakers shipped from Canada via UPS and they would have shown up on time, had someone from UPS not neglected to remove the package from the warehouse once Customs cleared it.
Some bicycle wheels from Canada, via FedEx, had the same complexities that you mention. Different carriers must have different arrangements.
