Reimporting same vehicle back to US:
Initially called CBP, DOT and EPA. DOT was confusing me saying i may need to revert back the daytime running lights even though we know that some states actually require it and most new cars are manufactured default with DRL. So i didnt want to remove it which was enabled after importing to Canada since this is not against law in any state and unnecessary expense and time waste.
Went to detroit tunnel. Inside the office, i showed the sale detail copy of the car to avoid tax and gave the documents which i collected during my import to Canada (along with the current ontario title). Officer gave back sale receipts and took the title and previous import docs for her to enter the forms.
She(officer) came back and asked me for the address and phone number.
In between cbp vehicle inspector came and asked who else was moving with me. He was saying that he could see somebody else's clothes/things
. I told that my family will be coming with me this weekend. Then he left.
She came back with all the forms printed and took my signature. Then she gave me my copy of DOT HS7, EPA 3520 and CBP 7501 (2 copies - one for dmv and one to keep it vehicle till it gets sold).
When i came back to car, the boxes and bags were rearranged, mostly in the trunk. I had to set few bags and boxes to fit/close the trunk. So have your things minimal while importing the car as they are supposed to check fully while importing the car. Overall it took 35-50 mins.
