Phosphatidylserine FDA Inspection History Review for US Buyers

Most US buyers of bulk phosphatidylserine (PS) meet FDA compliance history during supplier qualification, when a questionnaire asks whether the manufacturer has ever received a Form 483, a warning letter, or an import refusal. The question is legitimate, but it is often answered from memory instead of from FDA's public records.

The direct answer: FDA publishes a searchable record set covering inspection classifications, Form 483 observations, warning letters, import alerts, import refusals, and recalls, and a US importer is expected to use information like this when evaluating a foreign supplier under the Foreign Supplier Verification Program (FSVP). A clean search is useful evidence, but it is not proof that no inspection ever happened; a finding is a starting point for verification, not an automatic disqualification.

This review explains which FDA records exist for a PS supplier, how to search them, how to interpret the results, and how to document the screen in a supplier qualification file. It is a compliance-screening guide for US importers, distributors, supplement manufacturers, functional food brands, and their procurement, QA, and regulatory teams, not legal advice.

Where Nutranexa is mentioned, only verified public facts are used. Nutranexa identifies itself as Shandong Baianrui Biopharmaceutical Co., Ltd., founded in 2013, operating a 110,000+ m2 campus, and primarily serving export markets in Europe and North America. Its public pages list soy PS و sunflower PS, a published minimum order of 25 kg with 25 kg net per drum, and buyers can request current specifications, COA evidence, and registration-related files from the sales team.

The Direct Answer Buyers Need First

Before an order, run the supplier through FDA's public compliance records:

The screen belongs at two moments: before supplier approval, and again when new information appears or on a defined schedule. Under FSVP, an importer must evaluate a foreign supplier's performance and the risk of the food, document the evaluation, and re-evaluate when needed and at least every three years. The FDA record screen is one input into that evaluation, not the whole file.

What FDA Inspection Records Exist for a PS Supplier

FDA inspects facilities that manufacture, process, pack, or hold FDA-regulated products, including foreign facilities whose products enter the United States. Inspection activity is grouped into project areas, and a single visit can cover more than one.

The public disclosure picture has three layers: final inspection classifications in the inspections database and Data Dashboard, inspectional observations on a Form 483 at closeout, and separate databases for warning letters, import alerts, import refusals, and recalls.

The databases are not a complete census: FDA's inspections database excludes state-conducted inspections, pre-approval inspections, mammography facility inspections, inspections awaiting final enforcement action, and nonclinical laboratory inspections. A supplier with no rows has no public findings in the searched records, not a guarantee that the facility was never inspected.

Form 483: What It Is and What It Does Not Prove

A Form 483 is issued to facility management at the conclusion of an inspection when the investigator observed conditions that, in the investigator's judgment, may constitute violations of the Federal Food, Drug, and Cosmetic Act and related acts.

Three points matter for buyers:

1. A Form 483 is not a final agency determination. FDA considers the observations with the Establishment Inspection Report, evidence collected on site, and the facility's responses before deciding on further action.
2. Facilities are encouraged to respond in writing with a corrective action plan and implement it expeditiously; the response is part of the record a buyer should request.
3. A Form 483 is not an all-inclusive list of deviations. Investigators note what they observed; other conditions may exist that are not cited.

For a PS supplier, a Form 483 observation should be evaluated for relevance, dates, and correction rather than treated as a yes-or-no failure.

Inspection Classifications: NAI, VAI, and OAI

FDA classifies covered inspections into three categories:

Two cautions: an OAI classification does not guarantee an enforcement action and can result from issues other than food safety, such as labeling; and classifications are facility- and project-area-specific, so one product line does not automatically describe every product the facility makes.

Warning Letters and Closeout Letters

FDA warning letters are advisory actions issued only for violations of regulatory significance. For a supplier screen, search the Warning Letters page by exact legal entity, trading names, and facility names; check whether a response letter or closeout letter is posted; and note the date and subject. A closeout letter indicates FDA considered the listed violations adequately corrected, while a missing response letter does not mean the firm is ignoring the issue, because response letters are posted only at the firm's request. A labeling letter from 2019 is a different risk from an active CGMP warning letter for the exact facility and product line.

Import Alerts, Import Refusals, and Recalls in the Same File

The compliance-history screen extends beyond inspections:

• Import alerts. An alert can place a firm's products under detention without physical examination (DWPE), exclude them on a green list, or put them under intensified surveillance on a yellow list. Alerts are product-, firm-, and country-specific and update in real time; the FDA import alert and DWPE review covers screening and detention response.
• Import refusals. The monthly Import Refusals Report lists products refused admission and the reason. A refusal is entry- and product-specific and can be searched by supplier name, product description, and refusal charge.
• Recalls. Classified recalls appear in the weekly Enforcement Report with Class I, II, or III assigned by relative health hazard. The recalling firm listed may not be the actual ingredient manufacturer, so confirm the relationship before drawing conclusions.

These records answer different questions than an inspection classification, and FSVP explicitly names them when it requires an importer to evaluate information relevant to the supplier's compliance with FDA food safety regulations.

Why the FSVP Supplier Evaluation Requires This Screen

The FSVP importer checklist explains the program structure: the importer must develop a written program for each food and foreign supplier, perform a hazard analysis, evaluate and approve the supplier, verify performance, and keep records. The evaluation step is where the FDA record screen fits.

Under 21 CFR 1.505, the evaluation must consider the hazard analysis of the food, the entities that minimize or prevent hazards, and foreign supplier performance, including the supplier's procedures and practices, applicable FDA food safety regulations and information relevant to compliance (such as whether the supplier is the subject of an FDA warning letter, import alert, or other compliance action), and the supplier's food safety history, including test results, audit results, and responsiveness in correcting problems. The importer must document the evaluation, approve the supplier on that basis, and re-evaluate when new information appears and at least every three years. For a supplement manufacturer buying PS through a distributor, the same discipline can live in the supplier onboarding و annual supplier review files even when FSVP sits with the importer of record.

How to Run the FDA Compliance-History Screen

Use FDA's public tools in this order:

1. Lock the exact entity. Record the legal company name, trading names, factory name, and any FDA registration or FEI reference for the facility that makes the quoted PS grade.
2. Search the Data Dashboard firm/supplier evaluation resources, which consolidate inspection classifications, citations, compliance actions, recalls, and import refusals and alerts.
3. Search the inspections database by firm name and project area, noting classification and end dates.
4. Search the Warning Letters page by company name and legal entity, noting issue date, subject, and any posted response or closeout letter.
5. Search import alerts by firm name and country/area, checking the product code and red, green, or yellow list status.
6. Search the Import Refusals Report by supplier name and product description.
7. Search the Enforcement Report for recalls tied to the firm name, confirming whether the recalling firm is the actual PS manufacturer.
8. Request supplier evidence. Ask for current inspection-related files, any Form 483 and response, warning letters and closeout letters, and audit reports the supplier will share.
9. Document the screen with search date, tools, entity searched, findings, and decision, and store it with the documents for PS ingredients checklist.

How to Interpret What You Find

The same finding means different things depending on product scope and timing. A 2018 warning letter about a different product line is historical context; an active OAI classification with a current warning letter for the exact facility and product type is a material risk that should change verification activities, not just the risk score.

What to Do When a Finding Appears

Work a finding through the qualification file rather than quietly dropping the supplier or ignoring the record:

• Confirm identity. Verify the record belongs to the exact legal entity and facility that will manufacture the quoted PS lot.
• Request the primary documents. Ask for the Form 483 and written response, the warning letter and any closeout letter, or the refusal details and correction summary.
• Assess correction. Look for a closeout letter, an improved follow-up classification, or documented corrective actions.
• Adjust verification. A finding can justify more frequent COA review, third-party testing, a supplier audit, or stricter incoming inspection and warehouse release controls.
• Align the quality agreement. Put the re-screen obligation and change notification into the supplier quality agreement.
• Document the decision. Record why the supplier was approved, approved with conditions, or rejected, and set the next re-evaluation date.

For first-time buyers, the screen is also a test of supplier transparency: a supplier that provides its own records and documents corrections is easier to qualify than one that provides only a one-line denial.

Where Verified Nutranexa Facts Fit This Review

Nutranexa's public site supports the buyer-side screen. The company identifies itself as Shandong Baianrui Biopharmaceutical Co., Ltd., founded in 2013, with a 110,000+ m2 campus and a primary export focus on Europe and North America. The products pages show separate paths for Phosphatidylserine, الصويا Phosphatidylserine, and دوار الشمس Phosphatidylserine, with a published 25 kg minimum order and 25 kg net per drum.

For the FDA record screen, buyers need the exact legal entity and facility details, current registration-related files, and COA or specification evidence. Nutranexa directs buyers to request current specification, COA, packaging, and registration-related support files through الجودة والبحث والتطوير و اتصل بالمبيعات. As with any supplier, run the public searches against the exact legal entity and confirm current evidence directly; this article does not assert any specific inspection result for Nutranexa.

Conclusion

Screening a PS supplier's FDA inspection history is a concrete, repeatable step that belongs in every US supplier qualification file. Run the classification database, warning letter search, import alert and refusal checks, and recall search against the exact legal entity; read Form 483 observations as context rather than verdicts; and document the evaluation with a date, tools, findings, and a decision. The public databases are powerful but not comprehensive, so pair every screen with direct supplier evidence and verification activities.

الأسئلة الشائعة

How do I check a phosphatidylserine supplier's FDA inspection history?

Search FDA's Data Dashboard firm/supplier evaluation resources and inspections database for the exact legal entity and facility, then search the Warning Letters page, import alerts, the monthly Import Refusals Report, and the Enforcement Report. Record the search date, tools, findings, and decision in the supplier qualification file.

What is a Form 483 and does it mean a PS supplier is out of compliance?

A Form 483 lists inspectional observations issued at the closeout of an inspection when the investigator observed conditions that may constitute violations. It is not a final agency determination; FDA weighs the observations with the establishment inspection report, evidence, and the firm's responses before deciding on further action.

What do NAI, VAI, and OAI inspection classifications mean?

NAI means no objectionable conditions or practices were found, VAI means objectionable conditions were found but FDA is not prepared to take or recommend action, and OAI means regulatory or administrative actions are recommended. Classifications are facility- and project-area-specific and consider the firm's response and corrective actions.

Do US importers have to check FDA warning letters and import alerts for PS suppliers?

Under FSVP, importers must evaluate foreign supplier performance, including whether the supplier is the subject of an FDA warning letter, import alert, or other compliance action, and document the evaluation. The same discipline is good practice for any buyer approving a supplier.

Can I get a copy of a supplier's Form 483 or establishment inspection report?

Form 483 observations and some inspection records are available through FDA's OII FOIA electronic reading room and FOIA requests, and suppliers can share their own copies. Ask the supplier for primary documents before drawing conclusions.

What should I do if a PS supplier has an FDA warning letter or OAI inspection?

Confirm the record matches the exact facility and product, request the primary documents and corrective action evidence, check for a closeout letter or improved follow-up classification, and adjust verification activities such as testing, audits, or incoming inspection. Document the decision and the re-evaluation date.
