Importer Security Filing

Program Instructions

To access the ISF programs type ISF from any menu.


There is a Name and Address database keyed by customer number.
There can be up to 32000 addresses per customer.
There should be only one entry for each name and address. The same entry can be used for multiple entities on one shipment. For instance, the same name and address record could be used for the Buyer, Consignee and Ship To.

If a name and address is to be used as the consignee, the identifier is required and must be one of the forms acceptable to customs (EIN, SSN, or Customs Assigned Number).

If a DUNS number is provided it will be used in place of the name and address data.


The ISF TYPE is normally 10. It is 5 only for FROB, T&E and IE filings.

If there is an ISF Bond enter the Surety Code. If not supply either the bond holder EIN or the Bond Number.

Press F8 to go to the Entity Data Screen.
Select the appropriate Name/Address records from the Name/Address Database.

There can be multiple entries for each of the Entity Codes, but there must be at least one for each code.

The HTS and C/O data is also entered here. The manufacturer is selected from the Name/Address Database.

Press F9 from the Master Data Screen to go to the Reference And Container Data Screen. Container data is optional.
Data is sent by pressing F14 from the Master Data Screen.

When F1 or F14 are pressed, the data is validated. To save the data without validating, press F12.

When a successful transmission is received from CBP the ASSIGNED TRANSACTION NUMBER is displayed on the Master Data Screen.

Processing Results

The Customs results display is similar to the regular customs result display screen. However, the file number is that on the ISF Master Data Screen which is independent of any Breakbulk or Import file number.

The results typically have a message that is self explanatory.

For further information on the data contained in the transmission results consult the CATAIR ISF document.
