U.S. phosphatidylserine projects usually settle product, specification, and commercial terms long before anyone asks about the Importer Security Filing. Then the freight forwarder or customs broker sends a short email: the vessel is being booked, and the ISF data has to be ready. For importers who have not thought about the ten elements before, that email can arrive at the same time as the final invoice, the packing list, and the COA review.
The direct answer is that the Importer Security Filing, commonly called ISF or "10+2," is an advance cargo-security filing that the ISF Importer or an authorized agent must transmit electronically to CBP for non-bulk cargo arriving by vessel, with most data elements due no later than 24 hours before the cargo is laden aboard the vessel at the foreign port. Under 19 CFR Part 149, the ISF Importer is the party causing the goods to arrive in a U.S. port by vessel, which for a typical purchase will be the owner, purchaser, consignee, or a licensed customs broker acting as agent. The filing is separate from the customs entry, FDA prior notice, and FSVP.
For a phosphatidylserine buyer, the practical consequence is simple: start collecting ISF data when the purchase order is confirmed, not when the vessel is about to sail. Manufacturer identity, country of origin, HTS starting point, stuffing location, and consolidator are data points a PS manufacturer can usually confirm early if the buyer asks in the right way.
It is written for U.S. importers, distributors, supplement manufacturers, procurement teams, logistics coordinators, and quality teams, and it is operational guidance rather than legal advice; the final filing decision should be confirmed with the licensed broker or forwarder handling the shipment. Where Nutranexa is mentioned, only verified site facts are used: the site identifies the operating company as Shandong Baianrui Biopharmaceutical Co., Ltd., founded in 2013, operating a 110,000+ m2 campus, and primarily serving Europe and North America. For PS, the verified purchasing baseline is a 25 kg MOQ and 25 kg net per drum.
The Short Answer Buyers Need First
If your team is importing phosphatidylserine into the United States by ocean freight, treat ISF preparation as a separate step in the shipment file:
- Identify the ISF Importer, usually the U.S. owner, purchaser, or consignee, or a licensed customs broker acting as authorized agent.
- Confirm who will transmit the ISF electronically through a CBP-approved interchange system.
- Collect the ten data elements during order confirmation, not after dispatch.
- Deliver the eight lading-linked elements at least 24 hours before vessel loading at the foreign port, and confirm the stuffing location and consolidator as early as possible.
- Keep ISF separate from prior notice, FSVP, the customs entry, and the customs bond even when one broker handles all of them.
- Update the filing as more accurate information becomes available and before the goods arrive.
| Buyer question | Working answer |
|---|---|
| Who is responsible for the ISF on my PS import? | The ISF Importer, the party causing the goods to arrive in a U.S. port by vessel, or an authorized agent such as a licensed customs broker. |
| When is the filing due? | Most elements no later than 24 hours before lading at the foreign port; the stuffing location and consolidator no later than 24 hours before arrival. |
| Is ISF the same as prior notice or the entry? | No. ISF is advance cargo-security data. FDA prior notice, FSVP, and the CBP entry are separate controls in the same shipment file. |
| What happens if the ISF is late or wrong? | CBP may hold the cargo, and program guidance describes liquidated damages up to $5,000 per transmission with a $10,000 cap per ISF. |
| Does a small sample need an ISF? | If it moves by vessel as non-bulk cargo, the ISF requirement still applies; samples shipped by courier or air are not vessel cargo under this rule. |
Why ISF Is a Separate Import Task
The 10+2 rule is advance cargo-security data, not an entry or FDA filing
The ISF rule, published as an interim final rule in 2008 and in force since January 26, 2009, requires importers and vessel operating carriers to provide advance electronic data on non-bulk cargo shipments arriving in the United States by vessel. CBP program materials describe the initiative as "10+2": ten importer data elements plus two carrier requirements, the vessel stow plan and container status messages.
For phosphatidylserine, the distinction matters because buyers routinely merge several obligations into one "import paperwork" bucket. The ISF answers a security question: what cargo is moving, who is behind it, and where it was stuffed. FDA prior notice answers a different question about food imports, FSVP assigns hazard-control responsibility to the U.S. importer, and the CBP entry determines duty, release, and liquidation while a customs bond secures those obligations.
ISF ownership and who can transmit
Under 19 CFR 149.1, the ISF Importer is the party causing goods to arrive in a U.S. port by vessel, which for shipments other than foreign cargo remaining on board will be the goods' owner, purchaser, consignee, or an agent such as a licensed customs broker. An authorized agent may submit the filing, but the regulation requires the agent to retain powers of attorney in English.
What the buyer cannot delegate is the underlying data: seller identity, manufacturer identity, country of origin, HTS starting point, stuffing location, and consolidator all come from the transaction and the supplier. The customs broker handoff checklist explains how to keep the broker packet clean; the ISF is one specific filing inside that packet rather than the whole packet.
The 24-Hour Filing Clock for Phosphatidylserine Shipments
What must be transmitted at least 24 hours before vessel lading
Under 19 CFR 149.2(b), eight of the ten ISF elements are due no later than 24 hours before the cargo is laden aboard the vessel at the foreign port:
- seller
- buyer
- importer of record number
- consignee number(s)
- manufacturer (or supplier)
- ship to party
- country of origin
- commodity HTSUS number
For a drummed PS shipment, the practical deadline is set by the carrier and forwarder cut-off. "24 hours before lading" is the regulatory floor; in commercial practice, the forwarder will usually request the data earlier so it can validate the filing and resolve rejections. A buyer who waits for the final invoice to start collecting the manufacturer name, stuffing address, and HTS starting point is already compressing the window.
The two elements tied to arrival, not lading
The remaining two importer elements, container stuffing location and consolidator (stuffer), are due as early as possible and in no event later than 24 hours prior to arrival in a U.S. port, or at lading for shorter voyages. These are usually the easiest fields for a PS supplier to confirm because they describe where the drums were stuffed and who arranged it. For a factory-load shipment, the factory address is the stuffing location and the manufacturer can be named as the consolidator.
Updates, corrections, and the flexible elements
The ISF is not a one-time transmission. 19 CFR 149.2(d) requires the submitting party to update the filing if information changes or more accurate information becomes available before the goods enter a U.S. port, and to withdraw the filing if the goods are no longer intended for import. For the four flexible elements, CBP permits an initial response based on the best available data, with an update required as soon as more precise information is available and in no event less than 24 hours before arrival.
For PS importers, the workflow is simple: file on best-available data early, then update as the final invoice, packing list, bill of lading draft, and supplier confirmations arrive. The buyer should still send corrected manufacturer or stuffing details to the filer before arrival rather than assuming the first transmission is locked.
A Practical ISF Data Checklist for PS Imports
Use this table to assign owners and collect the ten elements during order confirmation:
| ISF element | What CBP asks for | What the PS buyer should request |
|---|---|---|
| Seller | Name and address of the entity selling the goods | Exact legal name and address from the quotation or sales contract, not a trading nickname |
| Buyer | Name and address of the entity buying the goods | The U.S. purchasing entity as shown on the purchase order |
| Importer of record number | IRS number, EIN, SSN, or CBP-assigned number | Confirm which U.S. entity holds importer of record responsibility |
| Consignee number(s) | IRS, EIN, SSN, or CBP-assigned number of the U.S. party on whose account goods ship | Match the consignee line on the bill of lading |
| Manufacturer (or supplier) | Entity that last manufactures, assembles, produces, or grows the commodity, or the supplier in the country of export | Legal company name and address, plus product route (general, soy, or sunflower PS) |
| Ship to party | First deliver-to party after customs release | The actual receiving facility, not only the corporate address |
| Country of origin | Country of manufacture, production, or growth | China for PS produced in China; confirm per shipment |
| Commodity HTSUS number | Duty/statistical reporting number, at least six digits | Confirm the HTS starting point under heading 2923 with the classification file |
| Container stuffing location | Physical location where goods were stuffed | Factory address if factory-loaded, or the consolidation warehouse |
| Consolidator (stuffer) | Party that stuffed the container or arranged stuffing | Manufacturer for factory-load, or the consolidator's legal name and address |
Three elements deserve extra attention: the manufacturer (or supplier), country of origin, and commodity HTSUS number must be linked at the line item level, so the buyer should send the supplier's legal identity, the route-specific product description, and the classification starting point together. The HS code review explains why classification should be a fact-based decision, and the certificate of origin review covers the origin evidence in the same file.
Where the Supplier File Helps
Manufacturer (or supplier) identity
The ISF manufacturer element asks for the name and address of the entity that last manufactures the commodity, or the party supplying the finished goods in the country from which they leave. A PS buyer should therefore confirm the exact legal entity behind the quote and the COA, rather than a brand name alone. Nutranexa presents its operating identity as Shandong Baianrui Biopharmaceutical Co., Ltd. and provides business-license and production-license documentation for buyer review, which is the kind of identity evidence that makes the ISF manufacturer line straightforward.
Container stuffing location and consolidator
For a drummed PS order, ask the supplier whether the shipment will be factory-loaded or consolidated. If the factory loads the container, the stuffing location is the factory address and the manufacturer is the consolidator. If a warehouse or logistics provider stuffs the container, capture that party's legal name and address.
Route identity and the HTS starting point
The commodity HTSUS number must be provided at least to the six-digit level and is strongest when it matches the invoice and COA descriptions. Because the site keeps general Phosphatidylserine, Soja Phosphatidylserine, and Girassol Phosphatidylserine on separate buyer paths, a buyer can keep route identity stable before the invoice, packing list, and ISF are drafted. The tariff schedules place lecithins and other phosphoaminolipids in heading 2923, the practical starting point discussed in the HS code resource, but the final number should still be confirmed for the exact shipment.
Need Help Organizing the ISF Data Packet?
If the supplier file, invoice wording, and route description are not clean enough to hand to the broker for ISF transmission, stop before booking the vessel. Use Contato de vendas to request the current route-specific specification path, manufacturing identity, packaging baseline, and shipment-detail support. The fastest requests include the route, destination country, expected quantity, and which ISF elements are still open.
Common Mistakes That Trigger ISF Problems
- Treating ISF as an afterthought the broker will "just handle," without confirming who is the ISF Importer and who transmits.
- Waiting for the final invoice to collect manufacturer identity, stuffing location, and the HTS starting point.
- Using a brand name instead of the exact legal manufacturer identity in the supplier file.
- Confusing ISF with prior notice, FSVP, the customs entry, or the customs bond, and assuming one filing covers the others.
- Filing once and never updating the ISF when the bill of lading, stuffing address, or ship-to location changes.
- Letting the commercial invoice describe the product differently from the COA, the classification file, and the ISF line item.
The practical fix is narrow and repeatable: assign an ISF owner at order confirmation, collect the ten elements with the supplier, transmit on best-available data, and update before arrival.
How Verified Nutranexa Facts Fit This Workflow
For buyers evaluating Nutranexa, several verified site facts make ISF preparation easier without changing who owns the filing. The site states that the company was founded in 2013, operates a 110,000+ m2 campus, and primarily serves Europe and North America, and it provides visible paths for Fabricação, Qualidade e P&D, and sales follow-up. The verified PS baseline of 25 kg MOQ e 25 kg líquidos por tambor supports early packaging and quantity confirmation, which feeds the invoice and stuffing details. Buyers should still confirm the exact legal identity, current address, and shipment-specific stuffing plan directly before any ISF transmission.
Related resources that belong in the same import file include the prior notice checklist, the FSVP importer checklist, the FDA food facility registration review, and the first sample shipment checklist. Each answers a different question, which is exactly why they should not be collapsed into one filing.

Perguntas frequentes
Who files the ISF for a phosphatidylserine import into the United States?
The ISF Importer, defined under 19 CFR 149.1 as the party causing the goods to arrive in a U.S. port by vessel, must ensure the filing is transmitted. The owner, purchaser, or consignee usually arranges for a licensed customs broker or forwarder to transmit it as an authorized agent, while the importer remains responsible for accurate underlying data.
Is ISF the same as prior notice, FSVP, or the customs entry?
No. ISF is an advance cargo-security filing required for non-bulk cargo arriving by vessel. FDA prior notice, FSVP, and the CBP entry are separate obligations that belong in the same shipment file but answer different questions.
What ISF data should buyers request from a PS supplier before booking?
Buyers should request the exact legal manufacturer name and address, product route, country of origin, HTS starting point, container stuffing location, consolidator identity, and shipment quantities. Most can be confirmed at order confirmation, well before the 24-hour lading deadline.
What happens if the ISF is filed late or contains wrong data?
CBP program materials describe liquidated damages of up to $5,000 per transmission with a $10,000 cap per ISF, and CBP may withhold release or transfer of the cargo until the required information is provided and reviewed. Transmit early and update accurately rather than finalizing at the last minute.
Does a small PS sample shipped by ocean freight need an ISF?
If the sample is non-bulk cargo arriving by vessel, the ISF requirement applies regardless of the small quantity. Samples shipped by courier or air freight are not vessel cargo and do not trigger this rule. The sample shipment checklist explains how to keep sample and commercial shipment files separate.
Conclusion
Phosphatidylserine ISF filing becomes manageable when U.S. importers treat it as an order-confirmation task rather than a last-minute broker detail. Identify the ISF Importer, confirm who transmits, collect the ten data elements with the supplier, meet the 24-hour lading deadline for the eight lading-linked fields, and update the filing as more accurate information arrives.
The supplier file matters more than most teams expect, because the manufacturer identity, country of origin, HTS starting point, stuffing location, and consolidator all originate with the seller. Asking for those details early keeps the ISF clean, the broker informed, and the shipment moving.
