The Importer Security Filing (ISF) is a US Customs and Border Protection (CBP) pre-arrival filing for ocean cargo. Data included on an ISF helps CBP identify security risks before imported goods enter the US. Here are 7 things you need to know when preparing your ISF filing.

Key Takeaways:

  1. Importers submit 10 data elements and the ocean carrier two data elements on the ISF. 
  2. The deadline to submit your ISF is 24 hours before the cargo is loaded onto a vessel bound for the US.
  3. The penalty for an ISF violation is $5,000 per infraction and up to $10,000 per shipment
  4. The ISF Importer is responsible for submitting the ISF, but a licensed customs broker can also file on their behalf with the Power of Attorney. 
  5. ISFs apply to ocean imports; bulk cargo is exempt.
  6. Importers must have a customs bond on file when submitting an ISF.
  7. ISFs are filed electronically through the Automated Commercial Environment (ACE) or the Automated Broker Interface (ABI).

I’ll detail exactly what you need to know about each of these ISF requirements and ensure you avoid fines or delays to your shipment.

1. 10+2 Data Elements

As the importer of record for your shipment, there are 10 pieces of information that you are required to provide on your ISF filing for all merchandise being imported at the most detailed bill of lading level. Additionally, there are two data elements that are needed from the carrier, hence another name for an ISF, the “10+2”.

The graphic shows the data importers are responsible for providing on their ISF.

Now that we’ve covered the data the importer must require on the ISF, here’s the data carriers must provide.

It’s essential that you and your carrier provide correct and accurate information. 

2. Filing Deadline

Submit ISF data elements about seller, buyer, importer of record number, consignee number(s), manufacturer (or supplier), ship to party, country of origin, and HTS number 24 hours prior to loading at the foreign port.

Submit ISF data elements on the container stuffing location and consolidator must be submitted no later than 24 hours prior to the ship’s arrival at a US port. 

Follow this process to submit all ISF data elements on time:

  1. Collect seller, butter, IOR, consignee, manufacturer/supplier, ship-to, country of origin and HTS number.
  2. Validate the bill of lading for your shipment against the one provided by the ocean vessel.
  3. Transmit ISF data or instruct your broker to do it on your behalf no later than 48 hours before loading. 

Practicing this procedure ensures there are no last-minute issues with your imports prior to your shipment being loaded. 

3. Penalty for Infractions

CBP assesses liquidated damages of $5,000 per ISF infraction and up to $10,000 per shipment for late, inaccurate, or incomplete filings. Non-compliant cargo may also face holds, refusal of unloading, or "do not load" orders. 

Mitigation of ISF errors depend on the type of mistake, corrective speed, and your compliance history with import regulations. Keep time-stamped records on all the updates you receive. 

4. Who is Responsible for Filing

CBP defines the ISF importer as the party responsible for causing the goods to be entered into the US commerce. This is typically the owner, purchaser, consignee of the goods. A licensed customs broker can file the ISF on if they’re given the power of attorney by the ISF importer.

5. Exemptions

There are some shipment types that allow for exceptions to the typical ISF requirements. Most notably, an ISF is only required for imports entering the US at an ocean port of entry. 

You do not need to submit an ISF for shipments entering by way of air or ground transportation. Additionally, an importer entering bulk cargo is not required to submit an ISF. 

Similarly, importers of break bulk cargo do need to submit an ISF, but they have until 24 hours before their freight arrives, rather than 24 hours before the freight is loaded. Foreign Cargo Remaining Onboard (FCRO), Immediate Exportation (IE), and Transportation & Exportation shipments also operate differently than a standard ISF (ISF Type 01).

6. Bond Coverage

ISF filings require a customs bond. You may use a continuous customs bond that covers all entries and ISF filings for an entire year or a single transaction bond (STB) that only covers one imported shipment. 

Many customs brokerages can sell you the ISF bond on its own. These bonds serve as guaranteed coverage for potential liquidated damages for any ISF violations.

7. How to Submit 

Submit your ISF electronically via the Automated Broker Interface (ABI) or the Automated Commercial Environment (ACE). You may also submit the ISF by hiring a customs broker, like USA Customs Clearance, to file it on your behalf. 

If you file your ISF and entry documentation together, you only need to provide these data elements once:

  • Importer of record number
  • Consignee number
  • Country of origin
  • Commodity HTSUS number if this number is provided at the 10-digit level

Providing this information will make the importing process more efficient for you.

Please can you confirm if the ISF filing is required for Air and Sea Shipments going into the USA.

Secondly can you forward me the ISF Document to be completed. IF the customer (once off importer) is here in South Africa and buys goods whilst in SA can he apply online whilst here for the ISP Filing?
