The Manifest System has been updated to accept Trailers to be declared in the Containers section of the Manifest. 

According to the updated Package Codes, ‘TT’ code stand for ‘Bag, tote’ and not ‘Trailer’.

Therefore, with immediate effect please refrain from using ‘TT’ for trailers in the Lines of Package Code but use the proper package code in the Lines of Packages and the trailer is to be declared in the Containers Section.
