nope, it should be trackable until you hold it in your hands.
On both of my orders from Outernet over USPS the parcel was trackable the whole way. last status is "delivered" that was set after some hours after i signed it on the door.
And yes, we don't have USPS here in Germany. After it leaves the US it is handed over to "Deutsche Post" (german postal service) an it is still trackable as mentioned above.
