Don't know about that sorry.  I paid the $100 for the commercial sticker.  It helps speed up things lots.  I tried to use their shipping manifest but didn't have a clue as to the codes and tell them so at the border if they ask.  I make up my own manifest with ship to info, item description and item cost.
A couple of people were going to send me in to pay and saw the sticker.  They just said have a great day.  Some asked to see the manifest and I told them why I did my own.  Didn't have a problem and just drove on through.  It's great.  I love it.  :)
 Even a stopped clock is right twice a day.
