Phosphatidylserine PFAS Screening: A US Buyer's Review

The PFAS question usually arrives through a customer questionnaire or retailer declaration, not through a regulation. The direct answer for a US buyer is to treat PFAS as a documented screening decision, not a yes-or-no certificate: confirm the current federal and state baseline, identify where PFAS could enter the specific PS route and its packaging, request supplier declarations and any test data with method and detection limits stated, decide whether independent testing is justified for the lot, and record the outcome in the ingredient file. A supplier statement that the product "contains no PFAS" is a claim to verify, not evidence by itself.

This is operational sourcing and quality guidance for US buyers of bulk phosphatidylserine, not legal, regulatory, or medical advice; confirm the exact position for your product, state, and contract with a qualified adviser.

What PFAS Screening Means for a PS Buyer

The question is real, and the answer is not one regulation

Per- and polyfluoroalkyl substances (PFAS) are a class of thousands of fluorinated chemicals. FDA says they can enter the food supply through crops and animals grown, raised, or processed in contaminated areas, and through processing and cookware in very small amounts. For a buyer, they are environmental and processing questions, not a standard row on a COA.

Three pressures make the question real in 2026:

• FDA has published years of PFAS testing results and is weighing future risk-management actions, so customers add PFAS to supplier questionnaires.
• State laws now restrict PFAS in food packaging, so the packaging components of a PS shipment are already in legal scope in some states.
• Contract manufacturers and retailers increasingly ask for declarations, and an unanswered question can hold up supplier approval even when no regulation requires testing.

Screening is a decision, not a pass-or-fail certificate

There is no single "PFAS test" the way there is an assay for PS content: a laboratory method measures a defined panel, and results depend on the matrix, method, and reporting basis. The buyer's question is not "is it PFAS-free?" but "what evidence do we need for our claim or decision?" That is the same discipline as identity testing under 21 CFR 111.75 and the supplier COA qualification review.

The Federal Baseline for PFAS in Food

What FDA's testing program found

Since 2019, FDA has tested more than 1,900 US market food samples using a validated LC-MS/MS method covering 30 PFAS. In the Total Diet Study, no PFAS was detected above the method detection limit in more than 95% (1,290 of 1,352) of fresh and processed foods; the exception is seafood, where 69% of TDS samples and 74% of the 2022 targeted survey samples had one or more PFAS detected.

For PS specifically, FDA has published no PFAS survey data or finding. That absence matters: the documented data point to environmental uptake in specific foods and regions, not a general problem in processed ingredient powders. Treat PFAS as a due-diligence question, not a known PS risk.

No PFAS action level for dietary ingredients today

FDA's risk-management toolbox includes action levels, a contamination level at which a food may be regarded as adulterated under section 402(a)(1) of the FD&C Act; they do not establish permissible levels. FDA is currently reviewing bottled water (a standard-of-quality regulation under 21 CFR 165.110), seafood, and infant formula as priorities. Dietary ingredients and supplements are not among the published priorities, and no PFAS action level exists for them.

For a buyer, no federal limit today means no automatic testing obligation, but also no safe-harbor number for a customer conversation; the file must explain the decision, not hide behind a nonexistent limit.

Import Alert 99-48: how FDA acts when PFAS is found

On March 20, 2024, FDA issued Import Alert 99-48, Detention without Physical Examination of Foods Due to Chemical Contamination, covering human foods with chemical contaminants that may present a safety concern, including PFAS. FDA has since added firms to its red list, including eight in 2025 for PFOA in imported clams. The alert is not PS-specific, but it shows how FDA acts: case by case, not through one class-wide limit.

Food-contact phase-out and EPA drinking-water rules

Two more federal pieces matter. In February 2024, FDA announced that grease-proofing agents containing PFAS are no longer sold in the US; in January 2025 it determined that the 35 related food contact notifications (FCNs) for paper and paperboard packaging are no longer effective. EPA's April 2024 drinking-water rule set enforceable limits for six PFAS: PFOA and PFOS at 4 ppt each, PFHxS, PFNA, and GenX at 10 ppt, plus a Hazard Index for mixtures; in May 2026, EPA proposed keeping the first two while rescinding the others. Drinking-water limits do not apply directly to food, but they explain the parts-per-trillion language buyers see.

State Laws That Can Touch a PS Shipment

Maine: toxics in packaging and certificates of compliance

Maine's Public Law Chapter 277 (LD 1433) amended the toxics-in-packaging chapter to add PFAS and phthalates alongside the existing heavy-metal limits. It prohibits the sale of food packaging with intentionally introduced PFAS above incidental presence, effective no earlier than January 1, 2022, or two years after the DEP determines a safer alternative is available, whichever is later. The law also requires covered manufacturers to develop a certificate of compliance. For a PS shipment, the drum liner and any food-contact component are the units to review.

California: AB 1200 and the 100 ppm threshold

California's AB 1200 added Health and Safety Code section 109000, prohibiting from January 1, 2023 the sale in the state of any plant-based food packaging containing regulated PFAS. Regulated PFAS means PFAS intentionally added with a functional or technical effect, or presence at or above 100 ppm measured as total organic fluorine. The definition matters: a declaration covering only "intentionally added PFAS" may not address the 100 ppm threshold, and vice versa.

These are packaging rules, not ingredient rules, but a 25 kg PS drum arrives with a liner, label, and sometimes pallet wrapping, and the buyer placing that packaging on the US market is the party most likely asked about it. The packaging declaration review explains how to keep food-contact declarations separate from the powder's COA, and the EU PPWR guide shows the parallel EU position.

Where PFAS Could Enter a PS Supply Chain

The table is a risk map, not a finding: without test data, "could enter" is a screening question, not a contamination result. Record the answers in the supplier onboarding file.

The US Buyer's PFAS Screening Workflow

1. Scope the exact product and route first

Lock the commercial item: general phosphatidylserine, soy PS, or sunflower PS; the grade; the supplier site; and the batch. PFAS evidence is only useful tied to the exact lot and route.

2. Define the claim the evidence must support

Three statements need three evidence sets:

• "PFAS is not intentionally used" requires a supplier process statement.
• "This lot was tested for a defined panel" requires a lot-linked laboratory report.
• "This product meets our customer's questionnaire" requires matching declaration wording.

3. Request declarations and evidence in writing

Ask the supplier in writing whether PFAS is intentionally used in the product or processing, what test data exists, which method and limits apply, and what raw-material and packaging controls are in place. Keep answers route- and lot-specific.

4. Decide whether independent testing is justified

For a first order, new supplier, route change, customer contract, or risk event, independent testing on a drawn sample is often the cleanest way to close the file; the third-party testing review covers panel definition, sampling, chain of custody, and decision rules.

5. Record the decision and keep it current

Close with a written outcome tied to the lot: no testing justified, tested and within agreed criteria, or held. File it with the COA and specification review و lot traceability records, and re-run the decision when source, process, site, or packaging changes.

What to Request From the Supplier

The documents for PS ingredients guide lists the baseline file for every PS purchase; the table above adds the PFAS-specific layer. Keep soy PS و sunflower PS files separate because the raw-material chain differs by source.

When Independent Testing Is Justified

The triggers are usually clear:

• a customer contract or retail requirement names PFAS testing;
• the supplier cannot provide any PFAS declaration or data;
• the source region or process raises an environmental concern;
• a route, site, or packaging change invalidates an earlier declaration;
• a questionnaire demands a guarantee the supplier cannot support.

When testing, agree the scope before sampling: the PFAS panel (FDA uses toxicological reference values for ten of the 30 PFAS in its method), the matrix (powder, liner, or both), the method and reporting units, and limits of detection and quantification. Keep a retain sample for dispute testing and tie the result to the exact batch so it supports the incoming inspection and warehouse release decision.

How PFAS Questions Fit the Rest of the Ingredient File

PFAS screening belongs inside the quality and document controls buyers already use. The customer questionnaire control article explains how to keep route-specific answers controlled, the supplier quality agreement makes declarations contractually current, and the annual supplier review is where a PFAS decision should be re-validated. The same discipline behind Supplement Facts labels و allergen statements applies: match the claim to the evidence and keep it current.

How Verified Nutranexa Facts Fit This Workflow

Nutranexa is a functional food ingredient manufacturer focused on phosphatidylserine, soy PS, sunflower PS, and soluble soybean polysaccharide. The primary entity, Shandong Baianrui Biopharmaceutical Co., Ltd., founded in 2013, operates a 110,000+ m2 campus with a primary export focus in Europe and North America. For PS, the baseline is a 25 kg minimum order quantity with 25 kg net per drum.

Those facts support the file: separate soy and sunflower routes keep the raw-material chain specific, and a 25 kg drum baseline keeps batch linkage simple, one drum, one label, one lot reference to reconcile with the COA, packing list, and any PFAS declaration. Nutranexa provides PS COA and specification evidence, factory, packaging, and dispatch imagery for review, supported by الجودة والبحث والتطوير و manufacturing context. None of that asserts PFAS results or a PFAS-free status: declarations, test data, and packaging documents must be confirmed for the exact route, lot, and configuration.

الأسئلة الشائعة

Is PFAS testing required for dietary supplement ingredients in the US?

No. FDA's published risk-management priorities are bottled water, seafood, and infant formula, and no PFAS action level exists for dietary ingredients. Testing is a buyer decision driven by contracts, retail requirements, and risk assessment.

Are there FDA limits for PFAS in food?

Not generally. FDA has no general PFAS action level for food; action levels are one tool it uses when a specific food and finding raise a health concern. EPA's April 2024 rule set drinking-water limits for six PFAS, and FDA is developing a bottled-water standard-of-quality regulation under 21 CFR 165.110. None apply directly to PS.

What should a US buyer verify for PFAS in imported PS?

Verify four things in writing: whether PFAS is intentionally used in the product or processing, what test data exists with method and limits, raw-material and packaging controls, and whether food-contact packaging meets state rules. Tie answers to the route, lot, and configuration.

Can a supplier certify a PS batch as PFAS-free?

A supplier can issue a declaration, but "PFAS-free" is only meaningful when the scope is defined: panel, matrix, method, and reporting limits. A blanket statement without method and thresholds is a claim to verify, not a certificate.

Do state laws restrict PFAS in bulk ingredient packaging?

Yes, at the packaging level. Maine restricts food packaging with intentionally introduced PFAS above incidental presence and requires certificates of compliance; California restricts plant-based food packaging containing regulated PFAS, defined as intentionally added PFAS or presence at or above 100 ppm total organic fluorine. The drum liner and food-contact components are the units to check.

How does FDA act when PFAS is found in food?

FDA evaluates findings case by case using toxicological reference values for ten PFAS and acts when a level may render food injurious to health. Import Alert 99-48, issued in March 2024, authorizes detention without physical examination for foods with chemical contaminants including PFAS, and firms have been added for PFAS in imported clams.

Conclusion

PFAS screening for a US PS purchase is a decision workflow, not a single certificate. The federal baseline: FDA has tested thousands of food samples, found most without detectable PFAS, has no PFAS action level for dietary ingredients, and is focusing future action on bottled water, seafood, and infant formula. State packaging rules in Maine and California put the drum liner and food-contact components in scope, which is why the packaging declaration belongs in the same file as the powder evidence. A defensible review scopes the route, defines the claim, requests declarations and data with method and threshold details, decides testing only when justified, and records the outcome. Buyers who re-validate the decision on change control can answer customer PFAS questionnaires with documents, not guesses.
