5-4. Review Hold Acknowledgment (TMC)
The Shipment Hold Acknowledgment, TMC, is used to verify receipt of and
compliance with the hold request/authorization. For shipments that can and will
be held, both the POE or POD clearance authority take the same action and return
the hold request/authorization modified into the format with appropriate entries
described below. This reformatted message is identified as the TMC.
5-5. Review Hold Denial (TML)
The TML message is used to indicate that the POE/POD cannot comply with the
hold request because the shipment has already been lifted, loaded, or is otherwise
uneconomical to hold. The appropriate entries for the TML (used by the POE
clearance authority) are described in the table below.
