AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
If you import goods from Nigeria to the US by sea, an Importer Security Filing (ISF, often called 10+2) must reach CBP at least 24 hours before the cargo is loaded on the vessel in Nigeria. It covers ten importer data elements under 19 CFR Part 149, needs a customs bond, and each late, inaccurate or missing filing exposes the importer to liquidated damages of $5,000 under the bond.
Who files, and when
The ISF Importer is the party causing the goods to arrive in the US by vessel: usually the owner, purchaser or consignee, or an agent such as a licensed customs broker acting for them (19 CFR 149.1). If you buy from a Lagos supplier and the goods are coming to you, that party is normally you, even if your forwarder or broker presses the button.
The clock runs from loading in Nigeria, not from arrival. That catches many first-time importers out, because the vessel may not reach Houston or New York for weeks, yet the filing is already late if it was not made a day before the container went on board.
| Data | Deadline under 19 CFR 149.2 |
|---|---|
| Seller, buyer, importer of record number, consignee number | 24 hours before lading at the foreign port |
| Manufacturer or supplier, ship-to party, country of origin, HTSUS number | 24 hours before lading; may be filed on best available data and updated |
| Container stuffing location, consolidator | As early as possible, and no later than 24 hours before arrival in a US port |
| Updates to any element | If information changes before the goods enter port limits |
| Withdrawal | If the goods are no longer meant for import into the US, with a reason |
A worked timeline
Example only: your forwarder tells you the container will be loaded in Lagos at 10:00 on a Monday. The ISF must be accepted by CBP before 10:00 on the Sunday, Lagos time. In practice you want it filed by Friday, because your supplier may need to confirm the manufacturer’s details and your broker may not file at weekends. The stuffing location and consolidator can follow, but no later than 24 hours before the vessel reaches the US.
The ten importer elements, and where to get them
Section 149.3(a) lists ten elements. For Nigerian shipments, most of the work is getting the supplier to send accurate details early.
- Seller: the Nigerian company selling the goods, as on the commercial invoice.
- Buyer: you, or the US party buying.
- Importer of record number: usually your EIN or CBP-assigned number.
- Consignee number: the party in the US receiving the goods.
- Manufacturer or supplier: who made the goods. A trading company in Lagos is not the manufacturer of goods it bought from a factory in Kano or Aba.
- Ship-to party: the first US delivery address after release.
- Country of origin: where the goods were made. This also decides whether the 12.5% Section 301 tariff on products of Nigeria applies.
- HTSUS number: at least the six-digit tariff heading.
- Container stuffing location: the warehouse or yard where the container was packed.
- Consolidator: the party that stuffed the container.
Manufacturer, country of origin and HTSUS number must be linked line by line. A container holding three products from two makers needs each product tied to its maker and origin.
Bond and liquidated damages
Section 149.5 requires the ISF Importer to have a bond: a basic importation and entry bond under 19 CFR 113.62, a dedicated ISF bond, or one of the other bonds listed. If you do not have one, the filing agent may post its own. Your bond is where the money risk sits. Under 113.62(j), the principal agrees to comply with Part 149, and the principal and surety agree "to pay liquidated damages of $5,000 for each violation."
Common violations are filing late, filing inaccurate data, not updating, or not filing at all. One container with a late filing and wrong data could be treated as more than one violation. CBP can mitigate claims, but you should not plan on it. See single or continuous bond for how the bond itself is chosen.
What ISF does not cover
- Air freight and courier parcels: ISF applies to vessel cargo only.
- Bulk cargo is exempt from the ISF importer elements, and break bulk has its own treatment under 149.4.
- ISF is not the customs entry. You still file an entry and pay duty when the goods arrive.
- ISF does not replace FDA prior notice for food, which for water shipments must be confirmed at least 8 hours before arrival under 21 CFR Part 1, Subpart I.
Steps that prevent a late ISF
- Put the ISF data in your purchase order: ask your supplier to send manufacturer names and addresses, HS codes and stuffing location when they confirm the order.
- Ask your forwarder for the vessel and expected loading date as soon as space is booked, and pass it to your broker.
- Agree with your broker who files and by when, and ask for the CBP acceptance message.
- Check the bill of lading against the ISF when it arrives; mismatches are a common cause of inaccuracy.
- If the plan changes, update or withdraw the filing rather than leaving it.

Where Pryme fits
Suppliers send ISF data faster when payment terms are clear. With a Pryme Business Account opened from the US, you can pay a Nigerian supplier in naira or dollars from one account, see the rate and fee before you approve through Swap, and keep a record of each payment against its shipment. The Compliance agent can remind you of filing dates you set. Outside Nigeria, Pryme’s services are provided through regulated partners.
Questions people ask
When is ISF due for a container from Lagos?
At least 24 hours before the container is loaded on the vessel in Nigeria. The stuffing location and consolidator may follow, but no later than 24 hours before arrival in the US.
What is the fine for a late ISF?
Under the basic importation bond, 19 CFR 113.62(j), the importer and surety agree to pay liquidated damages of $5,000 for each ISF violation. CBP may mitigate claims.
Do I need ISF for air cargo from Nigeria?
No. ISF applies to cargo arriving by vessel. Air cargo still needs a customs entry and, for food, FDA prior notice.
Who files ISF, me or my supplier?
The ISF Importer, usually the US buyer or consignee, or a broker acting for them. The Nigerian supplier provides much of the data.
