In this article, we’ll break it down for you and provide a comprehensive guide on the information that is required to file an ISF. From basic details like the importer of record’s contact information to more specific data like the manufacturer’s name and the cargo quantity, we’ll cover it all. So without further ado, let’s get started!

Importer Information
Importer of Record Number
When filing an ISF (Importer Security Filing), one of the important pieces of information that you will need is the Importer of Record Number. This number is assigned to you by the U.S. Customs and Border Protection (CBP) and is used to identify you as the importer responsible for the shipment. It is essential to have this number readily available when filing the ISF, as it provides CBP with the necessary information to process your shipment accurately.
Consignee Name and Address
Along with the Importer of Record Number, you will also need to provide the consignee’s name and address. The consignee is the party to whom the goods are being shipped or the party who will ultimately receive the goods. It is crucial to enter the consignee’s correct name and address to ensure that the shipment is delivered promptly and to the correct location. Providing accurate and up-to-date information is essential for maintaining the smooth flow of the import process.
Manufacturer or Supplier Information
Additionally, when filing an ISF, you will be required to provide the manufacturer or supplier information. This information includes the name and address of the company that produced or supplied the goods you are importing. Including the manufacturer or supplier information helps CBP identify the origin of the goods and ensure compliance with any applicable regulations or requirements. It is important to provide this information accurately to avoid any delays or penalties in the import process.
Vessel and Voyage Information
Vessel Name
One of the key pieces of information required when filing an ISF is the vessel name. The vessel name refers to the name of the ship that will be used to transport your goods. Providing the correct vessel name is crucial as it helps CBP track and manage the movement of goods throughout the import process. Make sure to obtain the accurate vessel name from your shipping or freight forwarding company to ensure the smooth and efficient processing of your ISF.
Vessel Country of Origin
In addition to the vessel name, you will also need to provide the vessel’s country of origin. The country of origin is the country in which the vessel was registered or flagged. This information is important for CBP to determine the jurisdiction and regulations that apply to the vessel. Providing the correct country of origin for the vessel helps CBP ensure compliance with various laws and regulations governing international trade.
Estimated Arrival Date
When filing an ISF, estimating the arrival date of your goods is crucial. The estimated arrival date is the expected date when the vessel carrying your goods will arrive at the port of unlading, which is the port where your goods will be offloaded. Providing an accurate estimated arrival date allows CBP to plan and allocate resources efficiently, ensuring a smooth flow of goods through the port. It is important to work closely with your shipping or logistics provider to obtain the most accurate estimated arrival date.
Port of Unlading
The port of unlading is the specific port where your goods will be offloaded from the vessel. When filing an ISF, you will need to provide the name of this port. This information is crucial for CBP to track and monitor the movement of goods and ensure compliance with applicable regulations. Providing the correct port of unlading helps CBP route your goods appropriately and streamline the import process.

Container Information
Container Number
When filing an ISF, you must provide the container number. The container number is a unique identifier assigned to each shipping container. It allows for the identification and tracking of your goods throughout the transportation process. Providing the accurate container number is vital to avoid any confusion or delays in the import process.
Container Size and Type
Along with the container number, you will also need to provide the container size and type. The container size refers to the dimensions of the container, such as the length, width, and height, while the container type categorizes the container based on its construction and purpose. Common container types include dry containers, refrigerated containers, and open-top containers, among others. Accurately stating the container size and type ensures that CBP can effectively plan and allocate resources for the handling and inspection of your goods.
Seal Numbers
Seal numbers are another important piece of information required when filing an ISF. A seal number refers to a unique identifier that is used to secure the container. It provides a tamper-evident mechanism, allowing parties to identify if the container has been accessed or tampered with during transportation. Including the seal numbers in the ISF assists CBP in verifying the security and integrity of the container and its contents. Ensure that the seal numbers provided are accurate and match the actual seals affixed to the container to avoid any discrepancies or delays.
Bill of Lading and Booking Information
Bill of Lading Number
The Bill of Lading (B/L) number is a crucial piece of information necessary when filing an ISF. The B/L number serves as a receipt of goods and represents a contract of carriage between the shipper and the carrier. It includes important details such as the shipper’s and consignee’s names, the vessel and voyage information, and the description of the goods being shipped. Accurately inputting the B/L number in the ISF is vital for CBP to match the information and track the movement of goods effectively.
House Bill of Lading Number
In addition to the B/L number, if applicable, you may need to provide the House Bill of Lading (HBL) number. The HBL number is issued by the freight forwarder or non-vessel operating common carrier (NVOCC) and is used when there are multiple bills of lading issued for different portions of a single shipment. This number helps CBP accurately identify and track the goods associated with the specific HBL. If your shipment involves multiple bills of lading, it is essential to provide the accurate HBL number to ensure smooth processing of the ISF.
Master Bill of Lading Number
The Master Bill of Lading (MBL) number is another critical piece of information required when filing an ISF. The MBL number is issued by the ocean carrier and represents the entire shipment as a whole. It provides the carrier with a consolidated view of all the individual bills of lading under the same MBL number. Accurately providing the MBL number in the ISF allows CBP to effectively track and manage the consolidated shipment.
Booking Number
Lastly, you may be asked to provide the booking number when filing an ISF. The booking number is assigned by the ocean carrier or freight forwarder and serves as a reference for the specific shipment. It identifies the specific container(s) and the booking details. Including the booking number in the ISF ensures that CBP can accurately associate the filing with the correct shipment and container. It is important to provide the booking number exactly as it appears on the documentation provided by your shipping or logistics provider.

Foreign Port of Loaded
Port of Loading
When filing an ISF, you will need to provide the port of loading. The port of loading refers to the specific port where your goods were loaded onto the vessel for transportation. This information is crucial for CBP in tracking and managing the movement of goods throughout the import process. Providing the correct port of loading ensures accurate documentation and compliance with applicable regulations.
Foreign Port of Loaded Code
In addition to the port of loading, you may also be required to provide the foreign port of loaded code. The foreign port of loaded code is a standardized code used to identify the specific foreign port where your goods were loaded onto the vessel. These codes are assigned and recognized globally, allowing for efficient communication and processing of import-related information. It is important to provide the correct foreign port of loaded code to ensure accurate tracking and compliance.
Country of Origin Information
Country of Origin for Goods Being Shipped
When filing an ISF, you will need to specify the country of origin for the goods being shipped. The country of origin refers to the country in which the goods were produced, manufactured, or assembled. Providing accurate country of origin information is crucial, as it helps CBP determine the applicability of various trade agreements, tariff rates, and regulations. It is important to carefully determine and input the correct country of origin for each commodity being imported to ensure compliance with relevant laws and regulations.

Harmonized System Code (HS Code)
HS Code for Each Commodity
The Harmonized System (HS) code is a standardized numerical classification system used to classify and identify products for international trade. When filing an ISF, you will need to provide the HS code for each commodity being imported. The HS code allows CBP to determine the specific category and characteristics of the goods and helps ensure compliance with customs regulations and duty rates. Accurately identifying and providing the HS code for each commodity is vital for the proper assessment of duties and compliance with trade regulations.
Container Stuffing Location
Location Where the Container was Stuffed
Another piece of information required when filing an ISF is the location where the container was stuffed. The container stuffing location refers to the place where the goods were loaded into the shipping container. Accurately providing this information helps CBP verify the integrity and security of the container and ensures compliance with regulations. It is essential to state the correct container stuffing location to avoid any confusion or delays in the import process.

Party to be Notified
Name and Address of the Party to be Notified of Arrival
When filing an ISF, you will need to provide the name and address of the party to be notified of the arrival of the goods. This party is typically the consignee or their designated agent. CBP uses this information to inform the party of the pending arrival of the goods and any additional actions or documentation required. It is crucial to provide the correct name and address to ensure timely communication and coordination.
ISF Bond
Bond Type and Number (if applicable)
Lastly, depending on the circumstances and the value of the imported goods, you may be required to obtain an ISF bond. An ISF bond is a financial instrument that guarantees the payment of any potential penalties or liquidated damages if there are errors, omissions, or violations in the ISF filing. When filing an ISF, you will need to provide the bond type and number if applicable. It is essential to work with a knowledgeable customs broker or surety agency to determine if an ISF bond is required and to obtain the correct bond type and number if necessary.
In conclusion, filing an ISF requires a comprehensive understanding of the various information required by CBP. From importer information to vessel and voyage details, container information, bill of lading and booking information, foreign port of loaded data, country of origin information, HS codes, container stuffing location, party to be notified, and the possibility of an ISF bond, each piece of information plays a crucial role in ensuring the accurate processing and clearance of your goods. Attention to detail and accuracy are key when providing this information to CBP, as errors or omissions may lead to delays, penalties, or other complications in the import process. Working closely with experienced shipping and logistics partners and customs experts can help ensure a smooth and successful ISF filing experience.
