Phosphatidylserine and the FDA Sanitary Transportation Rule: What US Buyers Should Check

When a US buyer books the port-to-warehouse truck leg for an imported ingredient, the FDA sanitary transportation rule is often the last thing on the checklist. The direct answer for a phosphatidylserine buyer is that a standard shipment of sealed 25 kg drums of shelf-stable PS powder is generally outside the operational requirements of the rule, because the food is completely enclosed by a container and does not require temperature control for safety - but the buyer should still verify that exemption per shipment, know who the shipper is for the US inland leg, keep receiving checks, and hold transport-condition evidence in the ingredient file. The rule creates real duties for shippers, loaders, carriers, and receivers when the food is not fully enclosed, is shipped in bulk with direct vehicle contact, or requires temperature control.

This guide is for US importers, distributors, supplement manufacturers, functional food brands, procurement, QA, warehouse, and compliance teams buying bulk PS. It is not legal or medical advice and makes no medical treatment claims. Confirm the exact position for your product, route, packaging, and contract with a qualified adviser.

What the FDA Sanitary Transportation Rule Covers

The sanitary transportation rule is one of the foundational rules under the FDA Food Safety Modernization Act (FSMA). FDA published the final rule on April 6, 2016; businesses other than small businesses had to comply one year later (April 6, 2017), and small businesses had two years (April 6, 2018). FDA's goal is to prevent transportation practices that create food safety risks, such as improper refrigeration, inadequate cleaning between loads, and failure to protect food.

The rule applies to shippers, receivers, loaders, and carriers when food moves by motor or rail vehicle within the United States, whether or not it enters interstate commerce. FDA is explicit that the rule does not apply to transportation by ship or air because of limitations in the law, so the ocean leg from China is outside it; the domestic drayage and inland trucking legs can fall within it.

The rule covers four areas: vehicles and transportation equipment, transportation operations, training, and records. Vehicles and equipment must be designed, built, and maintained so they do not cause food to become unsafe. Operations must include adequate temperature controls where needed, protection from contamination by raw foods or nonfood items in the same load, and protection from cross-contact. Covered carriers must train personnel when they agree with the shipper to be responsible for sanitary conditions, and records must be available to FDA on request.

Two legal points raise the stakes: the subpart's criteria apply in determining whether food is adulterated under section 402(i) of the FD&C Act, and failure to comply is a prohibited act under section 301(hh). A transport failure is therefore an adulteration and compliance question, not just a logistics inconvenience.

Which Foods and Shipments Are Outside the Rule

The rule has a defined list of exclusions. The definition of transportation operations in 21 CFR 1.904 does not include activities associated with transporting food that is completely enclosed by a container, except food that requires temperature control for safety, compressed food gases, food contact substances, human food byproducts for animal food without further processing, and live food animals except molluscan shellfish. Farm activities are also excluded.

FDA's rule page adds the related exemptions: shippers, receivers, or carriers with less than $500,000 in average annual revenue; food transshipped through the United States; and food imported for future export that is neither consumed nor distributed in the United States.

The revenue threshold is a rolling three-year average of less than $500,000, adjusted for inflation from a 2011 baseline, so a small buyer can grow into coverage over time. Review it annually.

Where Sealed PS Drums Fit: The Completely Enclosed Question

The core buyer question is whether sealed PS drums count as food completely enclosed by a container. In practice, bulk PS is packed into a food-grade liner inside a sealed drum, typically 25 kg net per drum, closed and secured for shipment. That keeps the powder out of contact with the surrounding environment, exactly the condition the exclusion describes.

Two conditions must hold for the exclusion. First, the food must actually be completely enclosed at the time of transport. If the drums are opened, if powder is moved into open bags or vented cartons, or if the shipment is loaded as bulk with the food in direct contact with the vehicle, the exclusion no longer applies. The regulation cites examples such as an open wooden basket or crate, an open cardboard box, a vented cardboard box, or a vented plastic bag. Second, the food must not require temperature control for safety; a food that needs controlled temperatures to prevent it from becoming unsafe is back in the rule even when enclosed.

For PS, the practical assessment is that a shelf-stable powder under normal commercial shipping conditions does not require temperature control for safety. Confirm the exact product, packing configuration, and shipment conditions with the supplier for each order, because a change in formulation, moisture profile, or packaging could change the assessment. When in doubt, treat the shipment as covered and apply the checks below.

The exclusion is also not general legal immunity. The FD&C Act's broader adulteration provisions still prohibit holding or transporting food under insanitary conditions. A torn liner, water-damaged drum, pest sign, or strong off-odor should stop the shipment from release regardless of the exemption.

Who Is the Shipper for an Imported Drum Shipment?

Under the rule, a shipper is a person, such as the manufacturer or a freight broker, who arranges for the transportation of food in the United States by one or more carriers. For an imported PS order, that can point to more than one company on the same shipment.

If the overseas supplier or its freight forwarder arranges the US inland leg, the supplier can be the shipper for that leg. FDA states that foreign shippers who ship food to the US and arrange for the transfer of the intact container onto a motor or rail vehicle for transportation within the US are covered if the food will be consumed or distributed in the United States. If the US buyer books the drayage and inland trucking itself, the buyer is the shipper for that leg.

The shipper has primary responsibility but may reassign responsibilities to another covered party through a written agreement, such as a carrier or logistics contract. That is why the transportation terms of a PS purchase order and the carrier booking matter: the buyer should know in writing who is responsible for vehicle condition, cleaning, and any temperature controls, and should keep the agreement in the shipment record.

What Buyers Should Verify Even When the Exclusion Applies

For a typical sealed 25 kg PS drum order, the transport file is small but not empty. A disciplined buyer verifies four things per order:

1. Packing configuration. Confirm the drums are sealed with an intact liner, correctly labeled, and palletized so the powder stays completely enclosed during the inland leg. The dispatch imagery and packing records from the supplier support this check.
2. Temperature-control assessment. Confirm in writing that the product does not require temperature control for safety under the conditions of shipment, so the completely-enclosed exclusion holds for the domestic leg.
3. Who arranges the US leg. Identify whether the supplier, the freight forwarder, or the buyer books the drayage and inland trucking, and record who the shipper is for each leg.
4. Receiving control. At warehouse receipt, check drum integrity, seals, labels, lot codes, pallet condition, and any water, pest, or damage signs before release, and match the shipment to the COA and packing list.

These checks connect to the incoming inspection and warehouse release workflow and the Parti izlenebilirlik kontrol listesi; the transport record feeds those reviews rather than replacing them.

For a covered shipment, the buyer should go further: the shipper specifies sanitary conditions in writing, the loader confirms the vehicle is clean and free of visible pest evidence or incompatible previous cargo before loading, the carrier follows the written agreement and trains personnel, and the receiver assesses the food at arrival. Records are kept for 12 months beyond the termination of agreements or the period the procedures are in use.

A US Buyer's Sanitary Transport Review Checklist

• Confirm sealed drums, intact food-grade liner, correct labels, 25 kg net per drum, and palletization.
• Confirm the temperature-control assessment in writing for the exact product and shipment conditions.
• Map the domestic leg and record who arranges drayage, inland truck or rail, and final delivery.
• Identify the shipper for each covered leg and whether responsibilities are assigned in writing.
• For non-enclosed, bulk, or temperature-controlled shipments, request written sanitary specifications plus carrier cleaning and training records.
• At receipt, inspect drums, seals, labels, lot codes, and pallets; hold the shipment on water, pest, odor, or damage evidence.
• Keep transport records, agreements, and receiving evidence for 12 months, available to FDA on request.
• Review the revenue threshold and packing configuration annually because coverage can change.

How Sanitary Transport Fits the Rest of the Import File

The sanitary transportation rule is one of several FSMA and customs layers on a US PS import. Before arrival, the ISF filing, prior notice, ve FSVP importer controls handle the entry and supplier-verification side; the customs broker handoff routes entry documents at the port. The ocean leg is outside this rule, which is why marine cargo insurance stays a separate commercial decision. The domestic truck leg is where this rule can apply, and the Ambalaj Beyannamesi İncelemesi already flags transport-condition ownership. Finally, the purchase order specification review is where buyers lock in who arranges and pays for each leg.

SSS

Does the FDA sanitary transportation rule apply to sealed PS drums?

Generally no, for a standard shipment. The rule excludes food completely enclosed by a container, except food that requires temperature control for safety. A sealed 25 kg drum with an intact liner keeps the powder completely enclosed, and shelf-stable PS does not require temperature control under normal conditions, so the rule's operational requirements typically do not apply. Verify the packing and temperature assessment per shipment, because opened bags, vented cartons, bulk loading, or a temperature-control requirement would change the answer.

Is phosphatidylserine a food that requires temperature control for safety?

Under normal commercial conditions, no. PS is a shelf-stable powder that does not need controlled temperatures to prevent it from becoming unsafe during ambient transport, which is why the completely-enclosed exclusion can apply. Confirm the exact formulation, moisture profile, and shipping conditions in writing with the supplier, and treat any doubt as a reason to apply the full checks.

Who is the shipper for an imported PS shipment under the rule?

The shipper is the person who arranges the transportation in the United States, which can be the manufacturer, an exporter or freight forwarder, or the US buyer, depending on who books the leg. FDA confirms foreign shippers who arrange transfer of an intact container onto a motor or rail vehicle for US transportation are covered when the food will be consumed or distributed in the US. Record who arranged each leg and whether responsibilities were reassigned in writing.

What records must be kept under the sanitary transportation rule?

For covered operations, shippers retain records of specifications, operating temperatures, written agreements, and written procedures; carriers retain written cleaning and inspection procedures and training records; and any party that reassigns responsibilities keeps that agreement. Retention is 12 months beyond the termination of agreements or the period the procedures are in use, and training records run 12 months beyond the date the person stops performing the duties. Records must be available to FDA on request and can be originals, true copies, or electronic records.

Does the rule apply to the ocean leg of a PS shipment from China?

No. FDA states the requirements do not apply to transportation by ship or air because of limitations in the law. The ocean leg is handled under commercial and customs rules, including the bill of lading, Incoterms, and cargo insurance. The rule can apply to domestic movement by motor or rail vehicle, which is why buyers should map the drayage and inland truck legs separately.

Sonuç

For most US buyers, the sanitary transportation rule is a short, confirmable part of the shipment file: sealed 25 kg PS drums that stay completely enclosed and do not require temperature control sit outside the rule's operational requirements, and the buyer's job is to verify that configuration and keep receiving and transport evidence. The rule becomes an operational obligation only when the food is not completely enclosed, is shipped in bulk, or requires temperature control. Connecting the transport review to the purchase order, import filings, and warehouse receiving keeps the file defensible from factory to formulation.
