Block 5—Air Dimension. Enter the code A when
any single dimension (length, width, or height) is less
than 72 inches. When any single dimension is greater
than 72 inches, enter the code Z. When using code Z,
enter the actual dimension as an additional entry in the
Remarks section.
Block 10—Transportation Control Number (TCN).
The TCN is a 17-character data element assigned to
control and manage each shipment unit throughout the
transportation movement pipeline. See DOD 4500.32-R
for more information about TCN.
Block 12—Transportation Priority (TP). There are
four TPs used on the TCMD. They are determined by
the issue priority designator (IPD).
Block 17—Transportation Account Code (TAC).
The TAC is a four-position alphanumeric code. The first
position identifies the activity that will be charged
(billed) for all services for movement transportation of
the item within the DTS. All Navy-funded shipments are
identified by the letter N in the first position of the TAC.
The second, third, and fourth positions are assigned and
controlled by the sponsoring service/agency. These
codes are used to identify the purpose code (second
position), the specific fund to be charged (third
position), and the type of cargo or commodity being
shipped (fourth position). For example, a shipment in
response to a requisition with a document number
V12345-0001-G001 and cognizance symbol 7R
material would have TAC code N217 assigned. When
shipping the retrograde, using the same document
number, the TAC code will be N517.

the shipment unit.
Block 23—Weight. Enter the total weight of the
shipment unit, rounded off to the next higher whole
