What Is The Timeline For ISF Filing For Goods Being Transported Via Vessel?
So you’re wondering about the timeline for ISF filing for goods being transported via vessel. Well, when it comes to importing goods into the United States, there are a lot of rules and regulations to abide by, and one of them is the Importer Security Filing (ISF) requirement. This requirement was implemented by U.S. Customs and Border Protection (CBP) as a way to enhance security and facilitate the flow of goods. But how does this all work? How much time do you have to submit the ISF? Let’s break it down.
Timeline for ISF Filing for Goods Being Transported via Vessel
Overview of ISF Filing
ISF (Importer Security Filing), also known as 10+2 filing, is a requirement by U.S. Customs and Border Protection (CBP) that importers or their agents must fulfill when importing goods via vessel. The purpose of ISF filing is to enhance the security of the international supply chain by providing CBP with advanced information about inbound shipments.
When is ISF Filing Required?
ISF filing is required for goods imported into the United States by vessel. This includes both foreign goods and goods returning to the United States after having been previously exported. However, there are a few exceptions to the ISF filing requirement, such as goods exempt from entry or goods that qualify for an immediate exportation or transportation and exportation bond.

Pre-Arrival Filing Requirements
Before the arrival of the vessel carrying the goods, certain information must be submitted as part of the ISF filing. This information includes the buyer and seller of the goods, the manufacturer, the ship-to party, the container stuffing location, and the consolidator’s name and address, among others. This information needs to be submitted no later than 24 hours before the vessel’s departure from the last foreign port.
Advanced Manifest Filing
In addition to the ISF filing, importers or their agents must also submit an advanced manifest to CBP. The advanced manifest includes more detailed information about the goods being transported, such as the description, quantity, weight, and value. The advanced manifest must be submitted to CBP no later than 24 hours before loading the goods onto the vessel at the port of departure.

Transmitting the ISF to CBP
The ISF filing can be transmitted to CBP using various methods, such as submitting it manually through the CBP website or through the Automated Broker Interface (ABI). The ABI is the preferred method, as it allows for faster processing and reduces the risk of errors. The ISF filing must be transmitted to CBP no later than 24 hours before the vessel’s departure from the last foreign port.
Non-compliance and Penalties
Non-compliance with the ISF filing requirements can lead to severe consequences. If an ISF filing is not submitted, submitted late, or is incomplete, CBP may issue penalties to the importer or their agent. These penalties can range from monetary fines to shipment delays or even cargo holds. It is crucial for importers to ensure timely and accurate ISF filing to avoid such penalties and disruptions to their supply chain.
Timelines for ISF Filing
The specific timeline for ISF filing can vary depending on the type of shipment being transported via vessel. There are three main timelines to consider: regular shipments, consolidated shipments, and break bulk shipments. Let’s explore each timeline in more detail.
ISF Filing Timeline for Regular Shipments
For regular shipments, which consist of goods belonging to a single importer in a single container, the ISF filing must be submitted no later than 24 hours before the vessel’s departure from the last foreign port. It is crucial for importers or their agents to gather all the necessary information and submit the ISF filing in a timely manner to ensure compliance.
ISF Filing Timeline for Consolidated Shipments
Consolidated shipments, where multiple importers share a single container, have a slightly different ISF filing timeline. In this case, the party filing the ISF must submit the required information no later than 24 hours before the consolidated container is loaded onto the vessel at the foreign port. It is essential for all importers involved in the consolidated shipment to coordinate and provide the necessary information to the filing party in a timely manner.
ISF Filing Timeline for Break Bulk Shipments
Break bulk shipments, which are goods that are not containerized but are loaded directly onto the vessel, have a unique ISF filing timeline. In this case, the ISF filing must be submitted no later than 24 hours before the cargo is loaded onto the vessel at the foreign port. Importers or their agents must ensure they have all the required information ready and submitted within the specified timeframe.
Summary and Key Takeaways
Proper understanding and compliance with the ISF filing requirements are crucial for importers who transport goods via vessel. The timeline for ISF filing varies depending on the type of shipment but generally requires submission no later than 24 hours before the vessel’s departure from the last foreign port. Timely and accurate ISF filing helps to ensure the security of the international supply chain and avoid penalties or disruptions to the import process. Importers should work closely with their agents to gather the necessary information and transmit the ISF filing to CBP within the required timeframe.
