ISF filing (10+2)

An Importer Security Filing is a screening document, not a revenue document. CBP wants to know who stands behind a container before it is loaded, so the filing is due no later than 24 hours before the cargo is laden aboard the vessel at the foreign port. Nothing about the arrival date matters to that clock. The rule sits at 19 CFR 149 and applies to goods arriving by ocean vessel; air, truck and rail shipments have no ISF at all.

The obligation belongs to the ISF Importer, which for ordinary cargo means the owner, purchaser, consignee or their agent. We file as that agent under your power of attorney, and we file on receipt of documents rather than on a queue.

Ten from you, two from the carrier

Your ten are seller, buyer, importer of record number, consignee number, manufacturer or supplier, ship-to party, country of origin, the six-digit HTSUS number, container stuffing location and consolidator. The ocean carrier separately transmits a vessel stow plan and container status messages. That is the plus two, and it is not your problem.

Four elements may go in as a reasonable range and be refined later: manufacturer, ship-to party, country of origin and the HTSUS number. Stuffing location and consolidator can follow later still, up to 24 hours before arrival. Flexibility is a timing allowance, not a standing permission to be wrong. An ISF that was filed as an estimate and never updated is an inaccurate ISF, and CBP scores it that way.

Where these filings actually break

• No bill match. The filing has to tie to a bill of lading the carrier has already transmitted. A transposed digit, a booking number used in place of a bill number, or an ISF filed before the carrier files anything, all leave the record unmatched in ACE. To CBP an unmatched ISF reads much like no ISF.
• House versus master on consolidations. On NVOCC cargo the filing goes against the house bill, and the house bill has to be on file. Filing against the master on a co-loaded box is the classic LCL failure.
• Manufacturer confused with vendor. The element wants the party that actually made or grew the goods, not the trading company that invoiced you. On a factory-direct purchase they are the same. On a sourcing-agent purchase they are usually not.
• Documents arriving on loading day. If the invoice and packing list reach anyone the day the box is stuffed, the filing is already late no matter how fast it is transmitted.

The penalty is rarely the expensive part

CBP claims liquidated damages of $5,000 per violation for a late, inaccurate or missing filing, capped at $10,000 per ISF transaction, taken against the bond. Mitigation is possible and first offences are often reduced. The money is still not the real cost. A shipment with an ISF problem draws a hold, and a hold means free time burning at the terminal, a possible move to a centralised examination station, and an exam invoice that lands on you whatever the exam finds.

ISF-5, for cargo that is not staying

Freight remaining on board, and cargo moving under an immediate exportation or transportation and exportation in-bond, takes a shorter filing on the same clock: booking party, foreign port of unlading, place of delivery, ship-to party and the six-digit HTSUS number. Forwarders who get the 7512 right and forget the ISF-5 collect the same hold as an importer who forgot the ISF-10.

It has to be bonded

The filing has to be secured. A continuous importer bond covers your filings and is the normal arrangement for anyone shipping regularly. If you do not carry one, the alternatives are a single-transaction ISF bond or a rider. We tell you which applies before the first filing, not after CBP asks.

What we need from you

• Commercial invoice and packing list
• Booking confirmation, with master and house bill numbers
• Importer of record number: EIN, SSN or a CBP-assigned number
• Manufacturer name and address, not just the seller
• Container stuffing location and the party who stuffed it

Send those and the filing goes in the same day. Where an element is genuinely unknown at that point we file the permitted range, put a date on it, and close it out ourselves before the flexibility runs out. Nobody has to remind us.
