To ensure you will not be hit with unwanted penalties due to incorrect filings, please review the quick ISF overview and reference below and examine your compliance with CBP’s Importer Security Filing rule.

What is “10+2” Importer Security Filing (ISF)?

The Importer Security Filing is a U.S. Customs and Border Protection (CBP) regulation was developed to help prevent high-risk ocean shipments from being transported to the United States. It is commonly referred to as “10+2” because of the number of data elements required and requires importers to submit specific information pertaining to ocean cargo prior to departing the country of origin.

With 10+2, the importer bears ultimate responsibility for the accuracy and timeliness of the filing. ISF 10+2 requires advanced transmission of the data 24 hours prior to being laded on board at the port of discharge. All ISF filings must be done electronically via the vessel Automated Manifest System (AMS) or the Automated Broker Interface (ABI) by the ISF Importer or their agent (e.g., licensed customs broker).

The "10" data elements that importers are required to submit are:

  1. Seller

  2. Buyer

  3. Importer of record number / FTZ applicant identification number

  4. Consignee number(s)

  5. Manufacturer (or supplier)

  6. Ship to party

  7. Country of origin

  8. Commodity Harmonized Tariff Schedule of the United States (HTSUS) number

  9. Container stuffing location

  10. Consolidator
