As single transaction bonds for entry require a paper submission to CBP, how will a single transaction bond for a unified entry and submitted on the CBP Form 301 be matched to an electronic ISF filing? What is the process of notifying CBP that a single transaction bond is actually on file?

If a single transaction bond is used, the ISF Importer must denote the usage of the single transaction bond on the ISF by identifying activity Type 01 (basic importation), bond type 9 (single transaction), the surety code, and the bond reference number. The bond reference number is a unique serial number that appears on CBP Form 301 and is used for the surety company’s tracking purposes. It should be noted that this is not the same as the “Bond Number assigned by CBP,” which is found in the “CBP use only” block.

The unique ISF transaction number should be noted in block 29 of the CBP Form 3461(customs entry) upon paper document submission to CBP for unified entry filings. This will alert CBP that the single transaction bond covers both the ISF and the entry.
