The penalty for non-compliance with filing an Importer Security Filing (ISF) can vary depending on the circumstances and the specific requirements that have not been met.
In general, failing to file an ISF or filing an incomplete or inaccurate ISF can result in fines and other penalties from U.S. Customs and Border Protection (CBP). These penalties can range from a warning letter for a first-time offense to fines of up to $5,000 per violation for repeated or more serious offenses. In addition, CBP may detain or seize the relevant cargo until the ISF is properly filed.
It is important to comply with all ISF requirements to avoid potential penalties and delays in the importing process.
