What Is ISF Filing Status?

ISF Filing Status refers to the current stage or condition of an Importer Security Filing (ISF) after it has been submitted to U.S. Customs and Border Protection (CBP). This status reflects whether the filing has been accepted, rejected, amended, or is still pending.

The ISF, commonly known as the “10+2” filing, is required for ocean shipments entering the U.S. It must be submitted at least 24 hours before cargo is loaded onto the vessel at the foreign port. The ISF Filing Status helps CBP track shipment compliance, validate security data, and match your filing with the associated bill of lading.

A correct ISF status ensures your filing is matched to the cargo manifest and aids in risk assessment. Statuses such as “Accepted,” “Rejected,” or “No Bill Found” are common indicators importers need to interpret accurately to maintain compliance and avoid delays or penalties.

How To Check ISF Filing Status?

To check your Importer Security Filing (ISF) status, you have several reliable methods depending on how the filing was submitted:

  1. Through Your Customs Broker or Freight Forwarder
    Most brokers with access to the CBP Automated Commercial Environment (ACE) system can provide real-time updates on your ISF status. They can confirm whether it’s been accepted, rejected, or still pending.
  2. Directly via the ACE Secure Data Portal
    If you have ACE access, log in and enter your ISF Transaction Number or Bill of Lading number. The system will show status messages like “Accepted,” “Pending,” “Rejected,” “Hold,” or “No Bill Found.”
    • An “Accepted + Y” status means ISF is successfully matched with the manifest.
    • An “Accepted + N” or error indicates it hasn’t matched yet and may be pending correction or awaiting bill details.
  3. Notice Timing
    CBP typically issues an acknowledgment within 4 to 6 hours, though it can take up to 24 hours, especially if entered close to ocean loading times.
  4. If You Encounter Issues
    If you see messages like “No Bill Found” or don’t get a response, verify your Bill of Lading number and filing details. Contact your broker or the ACE Help Desk or local CBP port office to resolve mismatches.
  5. Penalties & Compliance
    Monitoring your ISF is crucial, CBP can impose fines up to $5,000 per violation for errors or late filings. Regularly checking and resolving discrepancies helps prevent delays and penalties.

Interpreting ISF Status Messages: Meaning/Actions Required

Understanding ISF status messages is pivotal for importers and customs compliance. In this guide, we will demystify the meanings behind ISF status messages and outline the necessary actions required to ensure a smooth international trade process.

1. “Accepted”: This status indicates that your ISF filing has been successfully received and processed by U.S. Customs and Border Protection (CBP). No immediate action is required.

2. “Rejected”: If your ISF is rejected, it means there are errors or missing information. You must review the rejection message carefully, correct the issues, and resubmit the filing.

3. “Pending”: A “Pending” status suggests that CBP is still processing your ISF. It’s essential to monitor it regularly, as further actions might be necessary depending on CBP’s feedback or requests for additional information.

4. “Hold” or “Exam Hold”: If your ISF is placed on hold, CBP may be conducting additional inspections or reviewing your submission. You should be prepared for potential delays and remain in contact with CBP or your customs broker.

5. “Cancelled”: A “Cancelled” status typically means that the ISF filing is no longer required due to changes in your shipping plans. In such cases, you should update your records accordingly.

6. “Amended”: An “Amended” status indicates that you’ve made changes to your ISF after the initial submission. Ensure that the amendments align with CBP regulations and requirements.

7. “No Bill Found”: This message suggests that the bill of lading information provided in your ISF does not match the CBP records. Verify the bill of lading details and resubmit if necessary.

Interpreting ISF status messages correctly allows you to take appropriate actions, ensuring compliance with customs regulations and smooth import operations. Regularly monitoring the status and promptly addressing any issues is key to a successful import process.

ISF Filing Status Codes: What Each Code Means

ISF filing status codes, also known as ISF disposition codes, are messages issued by U.S. Customs and Border Protection (CBP) to indicate the current status of your Importer Security Filing (ISF). These codes help importers determine whether their ISF has been filed successfully, if it meets compliance requirements, and whether it matches a bill of lading in CBP’s Automated Manifest System (AMS).

Understanding these codes is essential for maintaining compliance, preventing delays, and ensuring smooth cargo clearance.

Key ISF Disposition Codes And Their Meanings

S1 – Bill of Lading Match
The ISF has been filed and successfully matched with a bill of lading in AMS. This confirms that the ISF is in good standing.

S2 – No Bill Match
The ISF was filed, but CBP could not match it to a bill of lading in AMS. You should verify the bill number and filing details immediately.

S3 / S4 / S5 – No Bill Match (5, 20, or 30 Days After Filing)
The ISF remains unmatched even after a specified period following submission. This indicates a persistent issue that must be corrected to avoid holds or penalties.

S6 – No Bill Match, Wrong Type
The bill of lading exists in AMS but is a different type (e.g., house vs. master) than what was entered in the ISF. Correct the mismatch and refile if needed.

S7 – Duplicate ISF Filing
Another party has submitted an ISF using the same bill of lading and importer ID. Investigate for possible duplicate submissions or coordination issues.

3Z – ISF On File
The ISF has been submitted and is officially on file with CBP. This is a standard confirmation message indicating the filing has been received.

2O – ISF Hold for No ISF on File
A hold has been placed because no ISF was located for the shipment. Immediate filing is required to release the hold.

2P – ISF Hold for ISF Compliance Issue
A hold was applied due to errors, inconsistencies, or violations in the ISF. Corrections must be made to proceed with clearance.

2Q – Do Not Load – No ISF on File
The shipment cannot be loaded onto the vessel because no ISF was submitted. This is a critical issue that must be resolved before departure.

2R – Do Not Load – ISF Compliance Issue
The shipment is barred from loading due to serious compliance violations in the ISF data. Corrections are required to lift the restriction.

4O – ISF Hold Removed – No ISF on File
The previously applied hold due to missing ISF has been lifted after successful filing.

4P – ISF Hold Removed – ISF Compliance Issue
The hold caused by a compliance error has been removed after corrections were made.

4Q – Do Not Load Removed – No ISF on File
The “Do Not Load” instruction was lifted once the missing ISF was filed and accepted.

4R – Do Not Load Removed – ISF Compliance Issue
The “Do Not Load” flag was removed after resolving the ISF compliance problems.
