When stepping into international trade, one of the first questions new importers ask is, “how much does it cost to file ISF?” The Importer Security Filing (ISF), also known as “10+2,” is a U.S. Customs and Border Protection (CBP) requirement that helps prevent security risks before cargo arrives in the country. Understanding the filing costs, what influences them, and the potential penalties for mistakes is crucial for anyone bringing goods into the United States by ocean freight.
The Basic Filing Cost
The average cost to file an ISF ranges from $30 to $100 depending on the customs broker or filing service used. Most small importers work with licensed customs brokers who handle the filing on their behalf. Basic filings or those involving one importer and one supplier, usually sit at the lower end of this range. However, if the shipment involves multiple suppliers, complex documentation, or changes to existing data, the cost can climb higher.
Some brokers include ISF filing as part of a larger import service package, especially when they also handle customs clearance. In those cases, the fee might be slightly discounted. It’s wise for importers to clarify whether the ISF fee is included or billed separately to avoid unexpected charges.
Factors That Influence the Price
Several elements affect the final ISF filing cost. Complexity of the shipment is a major factor. Multiple suppliers or container consolidations can add to the workload. Timing also plays a role. If the importer waits until the last minute to file (the ISF must be submitted at least 24 hours before cargo is loaded at the foreign port), some brokers may charge a rush fee.
Additionally, the type of importer identification matters. Importers who use a CBP-assigned number rather than a continuous bond may incur a small surcharge since the process requires extra verification steps. Finally, the technology used, such as self-filing through specialized software, can reduce costs but demands more knowledge and responsibility from the importer.
The Cost of Non-Compliance
Failing to file an ISF correctly or on time can be far more expensive than the filing fee itself. CBP can issue penalties of up to $5,000 per violation, even if the mistake was unintentional. Late filings, inaccurate data, or incomplete information can trigger these fines, and repeat offenders risk increased inspections or shipment delays.
Beyond financial penalties, non-compliance can damage an importer’s reputation with CBP. Frequent errors or missed filings may place a company under additional scrutiny, potentially slowing future imports and increasing operational costs.

Saving on ISF Costs
Importers looking to manage costs should develop consistent communication with their suppliers. Early document sharing and clear coordination prevent last-minute filings that lead to rush fees or errors. Partnering with a trusted customs broker can also streamline the process, ensuring compliance without the risk of costly mistakes.
For high-volume importers, establishing an annual or continuous bond can be a strategic move. While it comes with an upfront cost, it simplifies the process and often reduces per-shipment filing expenses over time.
Conclusion
ISF filing is an unavoidable part of ocean freight importing into the U.S., but it doesn’t have to be an overwhelming or costly hurdle. While the filing fee itself is relatively modest (typically under $100) the true savings come from compliance, accuracy, and consistency. By planning ahead and partnering with a knowledgeable broker, importers can protect their cargo, avoid penalties, and keep their supply chain moving smoothly.
