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 checks reefer requirements before booking because equipment details can change time, cost, and risk.
Common mistake
Assuming reefer requirements are standard without asking about the actual shipment.
Paperwork note
For reefer, keep the written instruction or dispatch note close to the rate confirmation so the term has load-specific context.
