Shipping goods comes with a lot of rules. One of the most important is filing an ISF document for the USA. If it is late, wrong, or missing, it can lead to fines, shipment delays, and extra costs. We have seen these problems happen often. The best way to avoid them is to follow clear steps and keep everything organized. Using a digital customs brokerage service can make this process easy and safe.
What Is an Import Security Filing?
The import security filing ISF is a requirement by U.S. Customs and Border Protection (CBP). It applies to ocean shipments coming into the U.S. The filing gives CBP information about the shipment, the importer, and the supplier. This helps them keep cargo safe and secure.
An ISF usually includes:
- Importer of Record number.
- Consignee information.
- Seller and buyer names and addresses.
- Manufacturer or supplier information.
- Ship-to party details.
- Container stuffing location.
- Consolidator information.
- Bill of Lading (BOL) number.
- Commodity HTSUS code.
Carriers also submit vessel stow plans and container status messages. That is why this rule is often called “10+2.”
There is also ISF 5, which applies to cargo that is not formally entering U.S. commerce. This can include transit shipments, Foreign Trade Zone shipments, or Freight Remaining on Board (FROB). ISF 5 requires fewer details but still must be handled carefully.
Who Is Responsible for Filing the ISF?
Legally, the importer of record must file the ISF. In practice, importers often rely on customs brokers, freight forwarders, or vessel agents to handle it. Problems usually happen when everyone thinks someone else is taking care of it.
We have seen shipments held at ports because an ISF was late or had errors. Even small mistakes can lead to fines and extra costs for everyone involved. Using a digital customs brokerage service helps prevent these problems and keeps everyone on the same page.
When Should the ISF Be Filed?
The ISF needs to be submitted at least 24 hours before the cargo is loaded onto the ship. Failing to meet this deadline may lead to:
- Fines from CBP.
- Customs holds are delaying shipments.
- Denied permission to unload at the port.
Keeping track of deadlines is key. A simple mistake can cost thousands in penalties, plus extra fees like port storage and detention.
Steps to File an ISF Document for the USA
1. Gather All Required Information
The first step is to collect all necessary details. This includes information about the importer, consignee, supplier, and freight forwarder. Missing even one piece of information can cause a rejected filing or a compliance violation.
Commercial invoices and packing lists are also very important. They help make sure the ISF data matches the shipment. Without them, errors can happen, and penalties may follow.
2. Choose a Filing Method
To file ISF, you can follow mainly three methods:
- Use a Licensed Customs Broker – This is usually the easiest and most reliable way.
- Self-Filing with Software – Gives more control but requires knowledge of CBP’s systems.
- File directly via Automated Broker Interface (ABI) – For those registered with CBP’s ACE system.
We recommend using a digital system or broker. This makes the process smoother and helps avoid mistakes.
3. Submit Through CBP’s ACE Portal
After gathering all the information, the ISF must be uploaded into the Automated Manifest System (AMS) and submitted through CBP’s Automated Commercial Environment (ACE) portal.
The ISF must match the manifest data. If there is a mismatch, CBP may issue fines or hold the shipment. Accuracy at this stage saves time, money, and headaches.
4. Confirm Bill of Lading Linkage
One common problem is a mismatched Bill of Lading (BOL) number. The ISF must be linked to the correct BOL. Errors here can delay shipments and create disputes.
We always keep a documented Statement of Facts to protect stakeholders in case there is a mistake. This helps avoid arguments over delays, fees, or compliance issues.
5. Monitor and Update if Needed
Even after the ISF is filed, the work isn’t done. Any changes to the shipment must be updated before the vessel arrives. This can include:
- A new consignee.
- Corrected HTS code.
- Updated container location.
Failing to update an ISF carries the same risk as missing a filing. Monitoring updates ensures compliance and avoids unnecessary fines.
Risks of Late or Incorrect Filings
We have seen how late or incorrect ISFs can affect shipments. Penalties and costs can include:
- $5,000 per violation from CBP.
- Demurrage fees for containers held at the port.
- Detention fees for extended container holds.
- Port storage fees.
- Missed delivery deadlines.
A single mistake can quickly cost more than $10,000 when combining penalties and logistics fees.

- Centralize all ISF documents.

With the right support, ISF filings become routine, predictable, and stress-free.
FAQs
- What is an Import Security Filing?
An ISF is a required submission to CBP before a vessel arrives. It provides information about the shipment, importer, and supplier for safety and compliance.
- Can we file an ISF ourselves?
Yes, but accuracy is critical. You need access to CBP’s ACE portal or licensed software. Mistakes can lead to fines and shipment delays.
- Does ISF apply to all shipments?
No. Containerized cargo follows ISF 10+2. FROB or non-containerized shipments may follow different rules.
- How much does filing an ISF cost?
CBP does not charge a fee. Brokers or forwarders usually charge $30–$50 per filing. Higher costs come from penalties for errors or late filing.
- What happens if the ISF is late or incorrect?
CBP can issue fines, hold the shipment, and trigger additional demurrage, detention, and port storage fees. Costs can exceed $10,000 per shipment.
