What is the 24-hour rule concerning U.S. Customs?

The 24-hour rule concerning U.S. Customs requires that carriers transmit cargo data at least 24 hours before the cargo is unloaded at a U.S. port. This regulation is critical for national security and helps customs officials efficiently screen incoming shipments for compliance with U.S. laws and regulations. By mandating that this data is submitted in advance, Customs can identify potential risks and take necessary actions to mitigate them before the cargo arrives, thereby ensuring that only safe and compliant goods enter the country.

Additionally, this requirement streamlines the overall customs process, improving the efficiency and security of both importers and the customs service. The advance notice allows customs to allocate resources appropriately, prioritizing shipments that may require additional scrutiny or inspection. This proactive approach not only enhances trade facilitation but also helps minimize delays at the port.
