Subject: "2Z" - MASTER/HOUSE CONTAINER MIS-MATCH DISPOSITION CODE
Parties in ACE will note that the “2Z” - Master/House Container Mis-Match disposition code 
has been enhanced to include remarks in the status notification output (350/RC) from CBP.  The new remarks will identify if the “2Z” is generated because the “HOUSE BILL IS NOT FILE” or the “MASTER BILL IS NOT FILE” as a result of the bill not yet being added or perhaps deleted.   A “2Z” without remarks would identify that a true container mis-match in the equipment number supplied between the Master and House bill issuer is present. 

NOTE:  Each delete of a bill will generate a 2Z (when applicable) and trade partners should use the 2Z message to identify if this is an actual mismatch or the result of a bill delete and re-add.
