Importer Security Filing (ISF): the three deadlines

The Importer Security Filing is the one advance filing on a US ocean import that belongs to the importer rather than to the carrier. The carrier files its manifest; the importer files this. The shorthand 10+2 counts both: ten elements from the importer, two from the vessel operator.

It is a screening filing, not a customs entry. Nothing in it assesses duty, and the entry summary that does comes later. What it buys CBP is the chance to look at a container before it is loaded rather than after it has arrived, which is also the reason its deadline sits where it does.

Ten elements, and where they come from

19 CFR § 149.3(a) lists them: seller, buyer, importer of record number, consignee number, manufacturer or supplier, ship to party, country of origin, commodity HTSUS number, container stuffing location and consolidator.

Two details in that section do more work than the list. The elements are required “for each good listed at the six-digit HTSUS number at the lowest bill of lading level (i.e., at the house bill of lading level, if applicable)”, so the filing is per line of cargo rather than per container, and it attaches to the house bill of lading when you are moving under one. And the manufacturer, the country of origin and the HTSUS number have to be “linked to one another at the line item level”, so a mixed container is not three elements but three sets of three.

Read the list by who holds the answer and the shape of the problem appears. Six of the ten are yours: your contract, your identity, your classification, your delivery plan. Four are somebody else’s. The manufacturer and the country of origin are what the supplier says they are. The container stuffing location and the consolidator are facts about a yard at the other end of the trade, decided on a day you were not there.

Three deadlines, not one

The deadline most desks carry is “24 hours before loading”, and it is right about eight of the ten elements. § 149.2(b) splits the set:

• (b)(1) and (b)(2): the four party elements and the four cargo elements, “no later than 24 hours before the cargo is laden aboard the vessel at the foreign port.”
• (b)(3): container stuffing location and consolidator, “as early as possible, in no event later than 24 hours prior to arrival in a United States port.”

So two of the ten run on the arrival clock, not the lading clock. That is not a concession anyone granted out of kindness: those are the two facts nobody knows until the box has been packed, and a rule demanding them before loading would have demanded the impossible.

The third deadline is the one that catches a desk that filed on time. Under § 149.2(f), the four cargo elements may be filed on “the best available data available at the time” and then have to be updated “as soon as more precise or more accurate information is available, in no event less than 24 hours prior to arrival”. Paragraph (d) puts it more broadly still: the filer must update if, before the goods enter a US port, “any of the information submitted changes or more accurate information becomes available.”

A filing that was correct when it was made and stale by arrival has not been complied with. Which makes the ISF a record kept current for the length of the voyage rather than a form filed and closed, and the thing a desk is actually managing is not the submission. It is the four facts that may still move.

The regulation concedes you are relaying somebody else’s data

This is the paragraph worth knowing exists, because it is unusually candid for a customs rule. § 149.2(c) says that where the filer got the information from another party, CBP “will take into consideration how, in accordance with ordinary commercial practices, the presenting party acquired such information, and whether and how the presenting party is able to verify this information”, and where the filer “is not reasonably able to verify such information”, CBP will permit it to be presented “on the basis of what the party reasonably believes to be true.”

That is the regulator acknowledging the structure of the trade: the party on the hook for the filing is not the party who knows the facts. It is not a waiver, because reasonably believing something still means having a reason, and it is why an email thread in which the supplier stated the stuffing location on a date is worth more than a field typed from memory.

Cancelled shipments and the exempt cargoes

§ 149.2(e) is short and routinely forgotten: if the goods are no longer coming to the United States, the filing has to be withdrawn and the reason for the withdrawal transmitted to CBP. A cancelled booking leaves an open filing behind it unless somebody closes it.

Two cargoes sit outside the ordinary rule. § 149.4(a) exempts bulk cargo (oil, grain, coal, ore, and goods needing mechanical handling such as bricks, pig iron and steel beams) from the ISF requirement altogether. § 149.4(b) exempts break bulk from the 24-hours-before-lading deadline only: it still has to be filed, 24 hours before the cargo arrives. An importer shipping containers and break bulk on one contract is on two different timetables.

The bond, and the HTSUS trap

Two more practicalities. § 149.5(b) requires the ISF Importer to hold a bond, and if it does not, “the agent submitting the Importer Security Filing on behalf of the ISF Importer may post the agent’s bond”, which is common and worth knowing about rather than discovering in a broker’s invoice. § 149.5(c) requires an agent to keep powers of attorney “in English until revoked”, and revoked ones for five years.

And the classification trap, in § 149.3(a)(8). Six digits of HS code satisfy the ISF. But the section adds that the number “can only be used for entry purposes if it is provided at the 10-digit level or greater by the importer of record or its licensed customs broker.” Where the ISF and the entry go in one transmission under § 149.6, four fields need be given only once: importer of record number, consignee number, country of origin, and the HTSUS number if it was given at ten digits. File six and the same number has to be supplied again at entry.

What this costs a desk, and where Docket sits

The ISF is not hard to file. It is hard to file on time with facts that live in somebody else’s warehouse, and then hard to keep current while the vessel is at sea.

The four elements marked above as somebody else’s are the whole job: getting the supplier to state the manufacturer, the origin, the stuffing location and the consolidator, before loading where the rule wants them before loading, and then confirming nothing changed before arrival. That is a chasing problem with a legal deadline attached to it, and it runs on the same documents the rest of the pack does: the commercial invoice, the packing list and the bill of lading.

Docket does not file the ISF. What it does is know from the purchase contract which facts the filing needs and when, chase the supplier for them on email and then WhatsApp, SMS and a voice call, and read what arrives against the contract and the other documents so a changed origin or a different stuffing yard is caught while the box is still at sea rather than at the entry desk. Reading each arriving document against the others, field by field, is what import document checking software that chases the filing facts is for. And since the filing attaches at the lowest bill of lading level, the notify party and the house bill it sits on are worth checking in the same pass.

One more pre-arrival filing can ride on the same documents, and it is on a different clock. Where the consignment is food, FDA’s prior notice is due against arrival at the US port rather than against lading at the foreign one, and in hours rather than days. The ISF and the prior notice draw on the same supplier facts, so a single late reply can miss both deadlines on different authorities.
