How to Verify FDA-Registered Adult Diaper Factories: A Procurement Guide for Importers
When importing absorbent hygiene products into the United States, confirming a factory's FDA registration status isn't optional—it's a regulatory requirement. Adult diapers are classified as Class I medical devices under FDA 21 CFR 876.5920, which means the manufacturing facility must be registered with the FDA and the product must be listed. Yet many procurement teams discover compliance gaps only after a shipment is held at customs. This guide walks through exactly how to verify credentials before committing to a production run.
What FDA Registration Actually Means for Adult Incontinence Products
There's a common misconception that "FDA registered" means the FDA has approved the product. It doesn't. Establishment registration indicates the factory has notified the FDA of its existence and operations—it's a transparency mechanism, not a quality endorsement. The product itself goes through a separate device listing process.
For Class I incontinence care items (including absorbent briefs, protective underwear, and underpads), manufacturers must comply with 21 CFR Part 807 for establishment registration and device listing, plus 21 CFR Part 820 for Quality System Regulation (QSR). Some products that make specific clinical claims may fall under Class II requiring a 510(k) premarket notification.
According to the FDA Medical Device Registration and Listing database, there were approximately 23,000 registered foreign medical device establishments as of 2025. China accounts for roughly 18% of these registrations, with hygiene product manufacturers concentrated in Fujian, Guangdong, and Jiangsu provinces.
Step-by-Step: How to Verify a Factory's FDA Status
1. Search the Public FDA Database
Navigate to the FDA Establishment Registration & Device Listing database (access.fda.gov). Enter the manufacturer's name or registration number. If the factory is properly registered, the results will show:
- Establishment name and physical address — must match the factory you're evaluating
- Owner/Operator number — unique identifier assigned by FDA
- Registration number — begins with 3 digits indicating the fiscal year
- Device listings — shows which product categories are covered
A critical detail: foreign manufacturers must also designate a US Agent. The US Agent serves as the FDA's point of contact and must have a physical US address. If the factory cannot provide US Agent details, the registration is likely incomplete.
2. Verify the Registration Is Active (Not Just "Registered")
FDA registrations must be renewed annually between October 1 and December 31. A factory that registered in 2024 but failed to renew for 2026 is no longer compliant. Always request a copy of the current registration certificate and cross-check the dates.
3. Request the Device Listing Number
Establishment registration alone isn't sufficient. The specific product—adult diapers, pull-on protective underwear, booster pads—must have a device listing number. Different product categories require separate listings. A factory registered for Class I wound dressings is not automatically listed for incontinence briefs.
4. Confirm the Product Code and Regulation Number
For adult absorbent products, the relevant FDA product codes include:
| Product Code | Device Type | Regulation Number |
|---|---|---|
| EYQ | Pad, Interlabial | 876.5920 |
| EXU | Incontinence Garment, Disposable | 876.5920 |
Ask the factory exactly which product codes their device listing covers. Generic claims like "FDA registered for medical products" without a specific product code are a warning sign.
Red Flags When Evaluating Overseas Factories
After working with procurement teams across 88+ markets, these patterns consistently correlate with compliance issues:
- The factory provides only a certificate image but refuses to share the registration number. Legitimate manufacturers have nothing to hide—the database is public.
- The US Agent is a PO Box or virtual office with no verifiable business presence. FDA requires a physical address and an actual representative who can respond within 24 hours during emergencies.
- Device listing shows unrelated product categories. If the factory claims to make adult briefs but the listing only covers surgical drapes, there's a gap.
- Registration was completed through a third-party consultant that the factory cannot name—often means the registration was filed incorrectly or the consultant is no longer engaged.
Beyond FDA: The Full Compliance Picture
FDA registration is just one piece. Serious buyers also verify:
- ISO 13485:2016 — Medical device quality management system certification, which aligns closely with FDA QSR requirements
- CE Marking under EU MDR 2017/745 — Required for European market access
- GMP (Good Manufacturing Practice) — Covers facility hygiene, personnel training, and production controls
- California Proposition 65 — Particularly relevant for absorbent products sold in the US, regarding chemical content disclosures
Questions to Ask Before Signing a Production Agreement
A structured inquiry process saves months of back-and-forth. Send these questions in your first email:
- What is your FDA Establishment Registration number and when was the last renewal?
- Which specific device product codes and regulation numbers are listed under your registration?
- Who is your designated US Agent? Please provide their company name, physical address, and direct contact.
- Do you hold ISO 13485 certification? If so, from which notified body and when does it expire?
- Can you provide a Declaration of Conformity for the adult incontinence products you manufacture?
- What third-party testing has been conducted on your products (biocompatibility, absorbency, skin irritation)?
- How do you handle post-market surveillance and adverse event reporting?

Frequently Asked Questions
How can I check if an adult diaper factory is FDA registered?
Search the public FDA Establishment Registration & Device Listing database by entering the manufacturer's name, registration number, or owner/operator number. Verify that the registration is current (renewed within the last fiscal year) and that the device listing specifically covers incontinence products (product codes EYQ or EXU). Also confirm the factory has a legitimate US Agent with a physical US address.
Is FDA registration the same as FDA approval?
No. FDA registration means the establishment has notified the FDA of its operations—it's not a product approval or quality certification. Class I adult incontinence garments are typically 510(k) exempt, so they don't require premarket clearance. However, the factory must still comply with Quality System Regulation (21 CFR Part 820) and register annually. Registration simply means the FDA knows the facility exists.
Do all Chinese adult diaper factories need FDA registration to export to the USA?
Yes. Any foreign establishment that manufactures medical devices—including Class I incontinence products—for distribution in the United States must register with the FDA and list those devices. This applies regardless of whether the factory sells directly or through a US-based importer. The importer of record must also be identified in the listing.
What is the difference between FDA Class I and Class II for adult diapers?
Most standard adult absorbent briefs fall under Class I (21 CFR 876.5920), which is 510(k) exempt—meaning no premarket submission is required, only registration and listing. If a product makes specific therapeutic claims (e.g., "treats incontinence-associated dermatitis") or incorporates drug components, it may be classified as Class II and require a 510(k) premarket notification. Always confirm the classification with your manufacturer.
What certifications should I look for besides FDA registration?
Beyond FDA, look for ISO 13485:2016 (medical device quality management), CE marking under EU MDR 2017/745 for European markets, GMP certification for production hygiene, and relevant dermatological testing (skin irritation, sensitization). For specific markets, check country-specific requirements: Health Canada MDEL for Canada, TGA for Australia, and MDSAP for multi-market access.
