Carrier note
Use this term in context with the rate confirmation, broker communication, facility instructions, and billing paperwork. A short definition is useful, but the written load terms control the actual freight decision.
Carrier example
A carrier sees accessorial mentioned during dispatch and checks whether the rate confirmation says how approval, documentation, and billing should work.
Common mistake
Assuming accessorial is approved because it was discussed by phone.
Paperwork note
For accessorial, keep written approval, timestamps, receipts when relevant, BOL, POD, revised confirmation, and invoice notes.
