For any business importing goods into the U.S. by sea, a late Importer Security Filing (ISF) is a quick way to lose $5,000. U.S. Customs and Border Protection (CBP) enforces a strict \u201c24-Hour Rule\u201d that requires all cargo data to be submitted *before* your goods are loaded onto the vessel at the foreign port, not before the ship arrives in the States.<\/p>\n

This article breaks down the ISF (10+2) filing requirements to help you avoid these costly penalties. We will cover the specific data points needed, explain the filing timeline, and clarify who is ultimately responsible for submitting the information\u2014even when using a customs broker.<\/p>\n

What is ISF (10+2)?<\/h2>\n
\n

ISF (10+2) is a U.S. Customs and Border Protection (CBP) rule requiring importers and ocean carriers to electronically submit advance cargo data before goods are loaded onto a vessel bound for the United States. It involves 10 data elements from the importer and 2 from the carrier to enhance security screening.<\/p>\n<\/blockquote>\n

A Security Mandate for Ocean Imports<\/h3>\n

Importer Security Filing (ISF) is a regulation from U.S. Customs and Border Protection (CBP) under rule 19 CFR 149. It requires the electronic submission of supply chain data for all containerized ocean cargo arriving in the United States. The primary goal is to screen high-risk shipments to identify potential security threats before they arrive at U.S. ports. All data is filed electronically and must match the carrier’s Automated Manifest System (AMS) filing using the corresponding Bill of Lading number.<\/p>\n

Breaking Down the “10+2” Data Structure<\/h3>\n

The “10+2” name comes from the way data responsibilities are divided. The “10” refers to the data elements the importer provides, including the Seller, Buyer, Importer of Record number, Consignee number, Manufacturer, Country of Origin, and the 6-digit Commodity HTS code. The “2” refers to the two data elements the ocean carrier must submit: the Vessel Stowage Plan and the Container Status Messages (CSMs) that track the container’s journey. This split responsibility ensures CBP receives a complete picture by combining commercial data from the importer with logistical<\/a> data from the carrier.<\/p>\n

The “24-Hour Rule”: Before the Ship Leaves China<\/h2>\n
\n

The “24-Hour Rule” requires importers to electronically submit their Importer Security Filing (ISF) data to U.S. Customs at least 24 hours before cargo is loaded onto a vessel at the foreign port. This allows for pre-departure risk assessment and carries a $5,000 penalty for non-compliance.<\/p>\n<\/blockquote>\n\n\n\n\n\n\n

The Core Requirement: Filing Before Cargo Loading<\/h3>\n

The “24-Hour Rule” mandates that all Importer Security Filing (ISF) data gets submitted to U.S. Customs and Border Protection (CBP) a minimum of 24 hours before cargo is loaded onto the vessel at its foreign departure port. This deadline is strict and based on the local time in the port of origin, like a city in China, not on the ship’s estimated arrival time in the United States. The rule specifically applies to the 10 core data elements required for the initial security review; the two remaining data elements provided by the carrier follow a different submission timeline.<\/p>\n

Best Practices for Timely Filing<\/h3>\n

To ensure compliance and avoid issues, you should provide all necessary ISF information to your customs broker or filer at least 72 hours before the vessel is scheduled to depart. This three-day buffer helps account for weekends, holidays, or any last-minute data corrections that might be needed. A failure to file on time, even by just a few minutes, can result in a $5,000 penalty for each violation.<\/p>\n

It is also critical to make sure the Bill of Lading (BOL) number is correct and submitted promptly. CBP uses this number to connect your ISF declaration with the carrier’s cargo manifest for verification, and mismatches can cause delays or penalties.<\/p>\n

Data Points Required (Seller, Buyer, HS Code)<\/h2>\n
\n

An ISF filing requires 12 total data points submitted to U.S. Customs 24 hours before vessel loading. The importer provides 10 elements like seller\/buyer details and HTS codes, while the ocean carrier provides 2 elements detailing the vessel stow plan and container status.<\/p>\n<\/blockquote>\n

The “10” Importer Data Elements<\/h3>\n

The Importer of Record, or their agent, must electronically file ten data elements with Customs and Border Protection (CBP). This information provides details about the parties involved in the transaction and the specifics of the goods being shipped.<\/p>\n
