Importer Security Filing Bond

A customs bond is a surety guarantee required by U.S. CBP for most commercial import shipments. An ISF Bond specifically covers the financial risk of ISF non-compliance penalties ($5,000-$10,000 per violation). Importers without a continuous bond must purchase a single-entry bond for each ISF filing.

Frequently Asked Questions

Do I need a bond for every ISF?
Yes, a customs bond is required for ISF filings on formal entries. The bond guarantees payment of any penalties or duties owed.
What is the difference between a single-entry bond and a continuous bond?
A single-entry bond covers one shipment only. A continuous bond covers all imports for one year. Importers with regular imports save money with a continuous bond.
