The Ultimate Guide to ISF Filing: Nationwide Compliance From Miami to the East Coast

If you are importing commercial goods into the United States via ocean freight, navigating U.S. Customs and Border Protection (CBP) regulations is one of the most critical steps in your supply chain. At the forefront of these regulations is the Importer Security Filing (ISF), commonly known as the 10+2 rule.

Missing an ISF deadline or submitting inaccurate information can result in severe financial penalties, cargo holds, and major supply chain disruptions. Whether your ocean containers are landing at PortMiami, pushing through the bustling ports of New York and New Jersey, or arriving for Baltimore customs clearance, staying compliant is non-negotiable.

While we are rooted as a premier Miami customs broker, our digital EDI infrastructure allows us to seamlessly handle ISF filings and clear cargo in all 50 states, offering comprehensive coverage across the entire East Coast and beyond.

What is ISF Filing (The 10+2 Rule)?

The Importer Security Filing is a mandatory CBP regulation specifically for cargo arriving in the United States by ocean vessel. It does not apply to air freight or land border crossings.

The name “10+2” stems from the data points required to complete the security screening:

• 10 Data Elements: Required from the importer (or their authorized customs broker).
• 2 Data Elements: Required from the ocean carrier.

The core purpose of the ISF is to allow customs officials to evaluate the safety and security risks of incoming maritime cargo before it ever leaves the foreign port.

The Critical Deadline: When Must You File?

Timing is everything. CBP strictly mandates that the ISF must be submitted no later than 24 hours before the cargo is loaded onto the vessel at the last foreign port.

⚠️ The Cost of Non-Compliance: Submitting a late, incomplete, or inaccurate ISF can prompt CBP to issue liquidated damages of $5,000 per violation. Additionally, your cargo may be subject to intrusive customs examinations upon arrival at your port of entry—whether in Florida, Maryland, or New York—racking up expensive demurrage and storage fees.

Breakdown of the 10+2 Data Elements

To successfully file your ISF, you or your logistics partner must gather specific details from your supply chain entities.

The 10 Importer Data Elements

1. Seller (or Owner) Name and Address: The last known entity who sold the goods.
2. Buyer (or Owner) Name and Address: The last known entity purchasing the goods.
3. Importer of Record Number: The IRS, EIN, or SSN number of the entity liable for duties.
4. Consignee Number(s): The U.S. identification number of the party to whom the cargo is shipped.
5. Manufacturer (or Supplier) Name and Address: The entity that last manufactured, grew, or assembled the product.
6. Ship-To Party Name and Address: The first physical delivery location in the United States.
7. Country of Origin: The country where the merchandise was produced or manufactured.
8. Commodity HTSUS Number: The Harmonized Tariff Schedule classification code (minimum 6 digits required).
9. Container Stuffing Location: The physical location where the goods were loaded into the ocean container.
10. Consolidator (Stuffer) Name and Address: The party who packed the container or arranged the logistics.

The 2 Carrier Data Elements

1. Vessel Stow Plan: The layout and location of your container on the ship.
2. Container Status Messages (CSMs): Tracking updates regarding container movement.

Do You Need a Customs Bond for ISF?

Yes. CBP requires all ISF filings to be secured by a valid customs bond. Importers generally utilize one of two options:

Bond Type	Best Used For	Features
Continuous Customs Bond	High-volume or frequent importers.	Covers all import entries and ISF filings nationwide for a full year. Valid at all 50 states’ ports.
Single Transaction Bond	One-off or occasional importers.	Secures a single shipment, but CBP caps its use for ISF at five times per year before requiring a continuous bond.
