What is the Importer Security Filing (ISF)?
The Importer Security Filing, commonly called 10+2, is a U.S. Customs and Border Protection (CBP) regulation that requires importers to provide specific cargo data to CBP before goods are loaded onto a vessel destined for the United States. The filing must be submitted at least 24 hours prior to the vessels departure from the foreign port.
Why ISF Was Created
Implemented in November2015, ISF was designed to strengthen national security by giving CBP advanced notice of highrisk shipments. Early visibility enables the agency to target inspections, reduce the likelihood of contraband or hazardous material entry, and accelerate the clearance of lowrisk cargo.
Key Requirements
Importers (or their agents) must submit the following ten data elements:
- 1. Seller/Manufacturer Name and address
- 2. Buyer (Owner) Name and address
- 3. Ship To Party Name and address
- 4. Importer of Record (IOR) Name and address
- 5. Consignee Name and address
- 6. Country of Origin Where the goods were manufactured
- 7. Commodity HTSUS number Harmonized Tariff Schedule code
- 8. Container Stuffing Location Where the cargo was loaded into the container
- 9. Consolidator (if used) Name and address
- 10. EPA or other required permits For regulated commodities
In addition to the 10, importers must also provide two transportrelated data elements (the +2):
- Vessel Stowage Plan (or container status report)
- Bill of Lading (or other carrier documentation)
Filing Process
- Gather Data Collect the ten data elements and the two transport documents. Accuracy is crucial; mismatches trigger holds.
- Choose a Filing Method Most importers use an Automated Commercial Environment (ACE)approved software solution or a customs broker that submits the filing on their behalf.
- Submit Before the 24Hour Deadline The filing must be lodged at least 24 hours before the vessel departs the foreign port (or prior to loading for rail shipments).
- Confirm Receipt CBP issues an ISF acknowledgment (ISFACK) with a unique filing reference number. Keep this number for recordkeeping.
- Amendments (if needed) If any of the ten elements change before the vessel leaves, file an amendment promptly.
- Entry Submission After the vessel arrives in the U.S., the standard entry paperwork (entry summary, invoice, packing list, etc.) is filed. CBP crosschecks the entry data against the ISF.
Sample ISF Data Table
| Element | Example |
|---|---|
| Seller/Manufacturer | ABC Textiles Ltd., 12 Rue du Commerce, Paris, FR |
| Buyer (Owner) | XYZ Imports Inc., 250 Market St., San Francisco, CA, US |
| Country of Origin | France |
| HTSUS | 6204.62.00 |
| Container Stuffing Location | Port of Le Havre, France |
Penalties & Compliance Impact
Failure to file, late filing, or inaccurate data can result in:
- Monetary penalties of up to $5,000 per violation
- Customs holds and delayed release of cargo
- Increased inspections for future shipments
- Potential loss of Trusted Trader status under other programs
Repeated noncompliance may lead to more severe enforcement actions, including seizure of goods.
BestPractice Tips for Successful ISF Management
- Integrate Early Capture required data at the point of order creation, not after the shipment is booked.
- Maintain a Master Data List Keep a verified list of buyers, sellers, consolidators, and IORs to avoid spelling or address inconsistencies.
- Use a Reliable Broker Choose a customs broker experienced with ISF and capable of providing realtime filing status.
- Audit Regularly Conduct monthly reconciliations between ISF filings and entry summaries to spot discrepancies.
- Train Staff Ensure procurement, logistics, and compliance teams understand the 24hour deadline and required data elements.
- Plan for Amendments Have a clear process for quickly updating filings when purchase orders are changed.
- Leverage Technology Cloudbased trade compliance platforms can automate data pulls, generate filing files, and store ISFACKs for audit trails.
