Importer Security Filing (ISF)

Importer Security Filing (ISF) Updates

Avalon is committed to providing the highest level of service to our clients and has always taken a proactive approach to understanding ISF.


The Importer Security Filing (ISF, commonly known as "10+2") is an initiative created by U.S. Customs and Border Protection (CBP). The rule requires advance cargo information to be transmitted to CBP at least 24 hours before goods are loaded onto an ocean vessel for shipment to the United States. ISF was created for security reasons, pursuant to the SAFE Port Act. Importers are required to provide 10 data elements to CBP, while carriers provide 2 data elements.

The rule was published in the Federal Register on Nov. 26, 2008 and went into effect on Jan. 26, 2009. During the first year, CBP used a phased-in approach, where importers were warned of infractions. After the initial phase-in period, on Jan. 26, 2010, ISF became fully effective.

For more information on ISF or a Web Merlin demonstration, please contact our Marketing Department at or contact your local Avalon office.

Web Merlin™

Web Merlin continues to provide the best surety bond technology in the industry and will assist in managing your ISF compliance with underwriting automation, compliance messages and e-mail notification of ISF Bonds. Our portal offers a streamlined approach to issuing ISF Bonds and transmits the bond directly to CBP to support your compliance with the ISF rule. Web Merlin also contains several business rules to avoid rejections. We are currently programming Web Merlin to accept collateral online via EFT or credit card transaction in instances when it will be required. This will ensure quick and timely issuance of ISF-D Bonds to support your operation.

Avalon is also currently working on three key ISF issues, including assisting the NCBFAA in drafting a white paper to propose shortening the six-year statute of limitations currently in place for ISF, working through the ITSA to dispute CBP’s efforts to “double dip” against any and all Customs bond types for ISF claims, as well as outreach with various trade associations.

We thank you for your business and the time in reviewing our ISF materials, attending our webinars and learning more about our Web Merlin updates. We understand the significant impact that ISF has on your business and if you have any questions, please do not hesitate to contact your local Avalon office.
