Can The ISF src=”https://www.youtube.com/embed/?rel=0″ Amended Or Updated After Filing?
So, you’ve filed your ISF (Importer Security Filing) and now you’re wondering if you can make any changes or updates to it. Well, the good news is that yes, it is possible to amend or update your ISF even after it has been filed. Whether it’s a simple correction or a substantial modification, the U.S. Customs and Border Protection (CBP) allows importers to make changes to their ISF under certain conditions. In this article, we will explore the process and requirements for amending or updating an ISF after it has been submitted, ensuring that you have a clear understanding of the possibilities and limitations when it comes to making changes to your filing.

Overview of the ISF
The Importer Security Filing (ISF) is an essential requirement for importers that is enforced by U.S. Customs and Border Protection (CBP) as part of their efforts to enhance supply chain security. The ISF, also known as the 10+2 rule, requires importers or their customs brokers to submit specific information about their shipments to CBP before they are loaded onto vessels bound for the United States.
Definition of the ISF
The ISF is a comprehensive filing that includes ten data elements required from importers and two additional elements provided by carriers. These data elements cover vital information about the imported goods, such as the manufacturer, seller, and buyer details, as well as the origin and destination of the shipment.
Purpose of the ISF
The primary purpose of the ISF is to improve security measures for international trade and facilitate risk assessment by CBP. By collecting detailed information before the cargo arrives in the United States, CBP can identify potential threats and take necessary actions in advance. The ISF also helps in targeting high-risk shipments for additional scrutiny, reducing the risk of unauthorized goods entering the country, and promoting a more secure supply chain.
Filing Requirements
To comply with the ISF regulations, importers or their agents must submit the required data to CBP no later than 24 hours before the cargo is loaded onto the vessel in the foreign port of origin. It is crucial to submit accurate and complete information to avoid penalties or delays in customs clearance. Failure to comply with the ISF filing requirements can result in fines and potential shipment holds by the CBP.
Amendment of the ISF
Understanding the Need for Amendments
There are situations where importers may need to make amendments to their filed ISF. Amendments may be required due to errors or omissions in the initial filing or changes in the shipment details. It is essential to understand the circumstances that necessitate an amendment to ensure compliance with CBP regulations.
Is Amendment Possible After Filing?
Yes, it is possible to amend the ISF after filing, but it must be done before the cargo arrives in a U.S. port. Once the vessel carrying the shipment leaves the foreign port, amendments are generally not accepted. Therefore, importers must act promptly if they need to make any changes or corrections to their ISF.
Time Limitations for Amendments
To ensure timely amendments, importers must be aware of the filing deadlines and the time limitations set by CBP. Amendments can generally be made up to 24 hours before the estimated arrival of the vessel at the first U.S. port. It is crucial to submit amendments as soon as possible to allow sufficient time for CBP to review and process the changes before the arrival of the shipment.
Types of Amendments
Correcting Errors or Omissions
One common reason for amendments is correcting errors or omissions made in the initial ISF filing. It is important to review the submitted data for accuracy and completeness to avoid potential discrepancies. If errors are identified, the importer should promptly file an amendment to rectify the mistakes and provide the correct information.
Updating Information
Another situation that may require an amendment is when there are updates to the information provided in the initial ISF filing. For example, changes in the seller’s or buyer’s information, changes in the manufacturer, or modifications in the shipment’s origin or destination may necessitate an amendment.
Changing Previously Submitted Details
In some cases, importers may need to change details that were previously submitted in the ISF. This could include changes in the description of the goods, the quantity, or any other relevant data. It is essential to accurately communicate any changes to CBP to ensure compliance with the regulations.

Amending the ISF
Contacting CBP for Amendments
To make amendments to the ISF, importers or their customs brokers should contact CBP directly or through the designated electronic portal. CBP will provide instructions and guidance on how to proceed with the amendments.
Procedures for Amending
The exact procedures for amending the ISF may vary depending on the specific circumstances and the filing system used. In general, importers will be required to submit a new filing or update the existing filing with the corrected or new information. Following CBP’s instructions and guidelines for amendments is crucial to ensure a smooth process and avoid any potential penalties.
Required Documentation for Amendments
When making amendments to the ISF, importers may be asked to provide supporting documentation, such as invoices, bills of lading, or other relevant paperwork. These documents will help CBP verify the accuracy of the amendment and ensure compliance with import regulations. It is essential to keep all relevant documentation readily available to facilitate the amendment process.
Reasons for Amendments
Inaccurate or Incomplete Data
Amendments may be necessary if the initial ISF filing contains inaccurate or incomplete data. It is vital to ensure the accuracy and completeness of the information provided to CBP to maintain compliance with the regulations and avoid potential penalties.
Changes in Shipment Details
Changes in shipment details, such as the quantity, description, or value of the goods, may require amendments to the ISF. It is crucial to communicate any modifications to CBP in a timely manner to prevent any issues during the customs clearance process.
Updates in Importer Information
If there are updates in the importer’s information, such as a change in the company name or address, an amendment to the ISF is necessary. Keeping CBP informed of any changes ensures that the correct details are associated with the imported goods.
Implications of Amendments
Review Process by CBP
When amendments are made to the ISF, CBP reviews the changes to ensure compliance with the regulations and to verify the accuracy of the amended information. CBP may conduct further inspections or screenings if deemed necessary based on the amendment.
Potential Fines and Penalties
Importers must be aware that failure to make amendments when required or providing inaccurate information may result in fines or penalties imposed by CBP. It is crucial to comply with the amendment process and provide correct and timely information to avoid such consequences.
Impact on Customs Clearance
Amendments to the ISF may impact the customs clearance process if not handled efficiently. Delays in the review and acceptance of amendments can lead to delays in the release of the cargo. It is essential to promptly make amendments and liaise with CBP to ensure a smooth customs clearance process.

Deadline for Amendments
Timely Submission of Amendments
To avoid complications, importers must submit amendments to the ISF within the specified filing deadlines set by CBP. Timely submission allows sufficient time for CBP to review and process the amendments before the arrival of the shipment at a U.S. port.
Late Amendments and Consequences
Late amendments, i.e., amendments requested after the filing deadlines, may not be accepted by CBP. Importers must exercise diligence in timely filing amendments to avoid potential penalties or shipment holds due to non-compliance.
Grace Period for Amendments
There is generally no grace period for amendments to the ISF. Importers must adhere to the filing deadlines to ensure their amendments are processed in a timely manner. Failing to comply with the specified deadlines may result in penalties or disruption to the supply chain.
Amendment vs. Post-Summary Corrections
Distinguishing Between Amendments and Post-Summary Corrections
While amendments involve changes made to the ISF before the cargo arrives in the U.S., post-summary corrections (PSC) are made after the cargo has been discharged and actions have been taken to authorize its release. PSCs enable importers to correct certain errors or data discrepancies identified during the customs clearance process.
When to Use Each Option
Importers should use amendments when changes need to be made before the arrival of the cargo in the U.S. Amendments allow for corrections or updates to the ISF data. Post-summary corrections, on the other hand, are suitable for correcting errors or omissions identified during the customs clearance process, such as discrepancies in quantities or values.
Procedure for Post-Summary Corrections
The procedure for post-summary corrections may vary depending on the specific circumstances and the filing system used. Importers or their customs brokers should follow CBP’s guidelines for post-summary corrections to ensure compliance with customs regulations and facilitate a smooth process.
Amendment Fees
Possible Fees for Amendments
There may be fees associated with making amendments to the ISF. The exact amount will vary depending on various factors, such as the filing system used and the complexity of the amendment. Importers should consult the appropriate CBP resources or their customs brokers to determine the applicable fees.
Payment Process for Amendment Fees
Importers are responsible for paying the fees associated with amendments. The payment process may vary depending on the specific filing system used. Importers should follow CBP’s instructions for fee payment to ensure compliance and avoid any delays in processing the amendments.
Waiver or Reduction of Fees
While there may be fees for making amendments to the ISF, certain circumstances or exemptions may allow for waivers or reductions of these fees. Importers should check with CBP or consult their customs brokers to determine if they qualify for any waivers or reductions and the process to obtain them.
