What is Importer Security Filing (ISF)?

Importer Security Filing (ISF), often called “10+2,” is a mandatory filing that must be submitted by the importer or their agent to U.S. Customs and Border Protection (CBP) before cargo is shipped by sea to the United States. It helps CBP assess security risks and track shipments entering the country.

If you import goods by ocean freight into the U.S., ISF is something you cannot ignore. Failing to file or making late or inaccurate filings can result in costly penalties and delays.

When you hear about “ISF charges,” it generally refers to the service fees associated with filing the ISF and any penalties for non-compliance. Let’s break down exactly how these charges are determined:

1. ISF Filing Fees

Most importers do not file ISF themselves. Instead, they use customs brokers, freight forwarders, or specialized filing agents. These service providers charge a filing fee for submitting the ISF on your behalf.

  • Typical ISF filing fees: $30 to $100 per shipment, depending on your service provider and the complexity of your filing.
  • What the fee covers: Preparation, data verification, transmission to CBP, and confirmation of receipt.

2. Late or Incomplete Filing Penalties

CBP requires that ISF filings are submitted at least 24 hours before cargo is loaded onto the vessel bound for the U.S. If you file late, submit incomplete or inaccurate information, or fail to file altogether, you may face severe penalties.

  • Standard penalty amounts:
  • Late ISF filing: Up to $5,000 per violation
  • Inaccurate or incomplete ISF: Up to $5,000 per violation
  • Failure to file at all: Up to $5,000 per shipment

3. Amendment or Correction Fees

If you need to update or correct your ISF after submission (before cargo arrival), your service provider may charge additional fees. These are usually lower than the initial filing fee, typically in the $15 to $50 range.


Step-by-Step: How ISF is Filed and Charged

To help you understand the full process, here’s a simplified step-by-step breakdown:

1. Gather Required Information

Before an ISF can be filed, collect essential shipment details, including:

  • Seller and buyer names and addresses
  • Manufacturer and shipper details
  • Container stuffing location
  • Consolidator’s name and address
  • Importer of record information
  • Consignee details
  • Ship-to name and address
  • Vessel details (SCAC code and voyage number)
  • Bill of Lading number

2. Choose a Filing Service Provider

Most importers use customs brokers, freight forwarders, or online portals. The provider will charge an ISF filing fee, which depends on:

  • Provider’s pricing structure
  • Number of filings per month (bulk discounts may apply)
  • Complexity of the shipment

3. Submit the ISF to CBP

Your provider prepares and submits the ISF electronically to U.S. Customs. You pay the agreed-upon filing fee.

4. Receive Confirmation

After submission, your provider should confirm receipt from CBP and inform you of any errors or updates needed.

5. Make Corrections if Necessary

If updates or corrections are needed before cargo arrival, your provider may charge a smaller amendment fee.

6. Monitor Compliance and Avoid Penalties

Ensure all ISF requirements are met and that your service provider files on time. Failure or error can lead to significant penalties, which are billed to the “Importer of Record” (you or your business).


Key Aspects and Best Practices

Important Aspects to Keep in Mind

  • Timing: The ISF must be filed no later than 24 hours before your cargo is loaded onto the vessel.
  • Responsibility: The importer (or their agent) is responsible for ensuring correct and timely filing.
  • Record-Keeping: Maintain copies of all filings and confirmations for at least five years.

Best Practices for Managing ISF Charges

  • Choose reputable service providers – Look for established brokers or digital platforms with strong compliance records.
  • Bundle services – Many customs brokers offer bundled ISF and customs entry services at discounted rates.
  • Verify information early – Gather all information before shipping to avoid delays and mistakes.
  • Track deadlines rigorously – Set calendar reminders for ISF deadlines based on your shipment schedules.
  • Negotiate fees – If you have regular shipments, ask about volume discounts.

Cost Tips for Shipping with ISF in Mind

Managing ISF-related costs is possible with a few practical tips:

  • Shop around for providers: Don’t assume your freight forwarder’s ISF filing fee is the best available. Compare stand-alone ISF providers.
  • Avoid last-minute filings: Rush fees or penalties for late filings often exceed the base filing fee.
  • Consolidate shipments: Fewer, larger shipments mean fewer ISF filings and lower aggregate fees.
  • Stay compliant: The cost of a single penalty ($5,000) can wipe out years of savings.
  • Use digital tools: Many providers now offer online ISF portals, which can reduce mistakes and extra fees.

Benefits of Efficient ISF Filing

A smooth ISF process offers several operational advantages:

  • Prevents cargo holds and delays at U.S. ports
  • Reduces the risk of expensive CBP penalties
  • Improves overall visibility and control over your supply chain
  • Allows you to plan better and save on potential demurrage or storage fees

Challenges and Common Pitfalls

Even the best-prepared importers can run into challenges with ISF. Common issues include:

  • Incomplete data – Missing manufacturer or consolidator details can lead to rejected filings.
  • Communication lags – Slow information flow from overseas partners causes late filings.
  • Underestimating penalties – Some new importers are unaware of the $5,000-per-violation rule.
  • Over-reliance on providers – Ultimately, the importer is responsible, not the broker or forwarder.

Frequently Asked Questions (FAQs)

1. What happens if I don’t file my ISF on time?

If you miss the ISF filing deadline, U.S. CBP can impose penalties of up to $5,000 per shipment. Additionally, your cargo may be held at the port, leading to further delays and additional costs.

2. How much does it typically cost to file an ISF?

The typical ISF filing service fee ranges from $30 to $100 per shipment, depending on your filing agent or customs broker. Additional amendment or rush fees may apply if corrections or last-minute filings are necessary.

3. Who is responsible for paying ISF charges?

The importer of record (you or your company) is responsible for paying the ISF filing fee and any penalties for non-compliance. Your customs broker or freight forwarder usually charges you for the service, but the legal responsibility lies with the importer.

4. Can ISF be filed by anyone, or must it be a customs broker?

While the importer of record can technically file ISF directly using the correct electronic platform, most choose to use customs brokers, freight forwarders, or specialized ISF filing services for accuracy, convenience, and compliance.

5. Are there any ways to reduce my ISF costs?

Yes. Consider consolidating shipments, negotiating better rates with providers, using digital filing platforms to minimize errors, and ensuring timely, accurate filings to avoid expensive penalties.


Conclusion

ISF charges are a combination of service fees for filing—the cost for accuracy and timely compliance—and significant penalties for failing to meet CBP regulations. As an importer, understanding these charges and how to manage them efficiently is key to seamless ocean freight shipping into the U.S. By choosing reputable partners, organizing early, and keeping your information accurate, you can keep ISF costs low and avoid unnecessary risks to your business. Stay informed, stay organized, and you’ll navigate the ISF process with confidence.
