Short answer
Before a first bulk order of adult diapers, confirm who the label says made and distributes the product, ask for the manufacturer’s specification sheet, reconcile the unit of measure (units per bag, bags per case), and check the lot and date coding on the first case you receive. In the United States a protective garment for incontinence is a Class I device exempt from premarket notification, so no FDA clearance number exists to request.
Definition and scope
This guide covers buying adult incontinence briefs and similar protective garments in volume, whether you are a facility, a small business or a household buying cases. It also covers the variants buyers search for: buying adult diapers in bulk, wholesale incontinence products and bulk incontinence supplies. For choosing a product type and fit, see the adult incontinence product selection guide, the adult diaper size chart and the guide to disposable incontinence pads. Prices, brand rankings and health claims are outside this page.
What does the FDA say about the product?
Under 21 CFR 876.5920, a protective garment for incontinence is “a device that consists of absorbent padding and a fluid barrier and that is intended to protect an incontinent patient’s garment from the patient’s excreta.” The same section states that this generic type “does not include diapers for infants.” The classification is Class I (general controls). The device is exempt from the premarket notification procedures (510(k)) subject to the limitations in 21 CFR 876.9, and exempt from the current good manufacturing practice requirements of the quality management system regulation in part 820, except those concerning records and complaint files under 820.35.
What this means for a buyer: a seller who offers a “510(k) number” or says the product is “FDA approved” for an ordinary adult brief is not describing a document the regulation calls for. Treat such a statement as a claim to ask about, not as proof of quality.
What should I verify before placing a first order?
Start with the label identity. 21 CFR 801.1 requires the label of a device in package form to specify conspicuously the name and place of business of the manufacturer, packer or distributor. If that named company did not make the device, the name must be qualified with wording such as “Manufactured for” or “Distributed by.” For non-consumer packages the ZIP code must appear on the label or the labeling, including the invoice.
- Compare the name on the case, the name on the invoice and the name of the seller; they may legitimately differ, but the wording should say how they are connected.
- Confirm the product in the quote matches the item described in the manufacturer’s specification sheet (same model, size range and pack format).
- Check the product is a protective garment for adults, not an infant diaper, which the regulation excludes from this device type.
What documents should I ask the seller for?
21 CFR 876.5920 does not list a document set that a seller must hand over, so the list below is buyer practice, not a legal mandate.
| Document or detail | Why a buyer asks | Basis |
|---|---|---|
| Manufacturer specification sheet | Fixes the product, sizes and pack format you are actually buying | Buyer practice |
| Test method behind any absorbency figure | A number without a method cannot be compared; ISO 11948-1 is one published method for absorption capacity of the absorbent core | ISO catalogue entry |
| Name and address of manufacturer or distributor | Matches the label identity rule | 21 CFR 801.1 |
| Complaint and return contact | Class I manufacturers remain subject to records and complaint-file requirements | 21 CFR 876.5920(b), 820.35 |
| Storage conditions and lot or date coding | Lets you check the first case against the maker’s own statement | Buyer practice |
ISO 11948-1:1996, “Urine-absorbing aids – Part 1: Whole-product testing,” describes a method to determine the absorption capacity of the absorbent core of body-worn urine-absorbing aids. The ISO catalogue lists it as confirmed. A supplier quoting an absorbency figure can be asked which method and which report it comes from. Citing the standard is not the same as certification, and this page does not say it is required. A related, more recent standard is ISO 16021:2024, titled “Absorbent incontinence products for urine and/or faeces – Basic principles for evaluation of single-use adult products from the perspective of users and caregivers.”
What is the typical case or pack size and unit of measure?
Pack and case counts are set by each manufacturer, and 21 CFR 876.5920 does not fix them, so the specification sheet governs. The common error is comparing quotes in different units. Write each quote down as units per bag, bags per case and cases ordered, then compute the total unit count before comparing sellers. A quote per “case” from one seller and per “bag” from another is not comparable until reconciled. For supplier-side checks, the supplier risk assessment guide and the nursing home supply checklist show how larger buyers organise this.
Can small buyers or new businesses open an account?
Account opening is each supplier’s own policy. Ask directly what the supplier requires to open an account, whether it sells to individuals or small organisations, and whether there is a minimum order, and get the answers in writing along with the pack and unit-of-measure terms.
What shelf life and lot information should be on the label?
21 CFR 876.5920 does not set a shelf life or expiry date for adult briefs, and 21 CFR 801.1 addresses name and place of business, not dates. Any date or lot coding on a case is therefore the manufacturer’s own choice. Ask the manufacturer for its stated storage conditions and how its lot or date code is formatted, then check that the case and the inner bag carry matching codes. If you buy medical supplies that do carry unique device identifiers, the UDI labels guide explains what those labels contain. If a lot is later the subject of a safety action, the medical device recall guide explains the process; keeping lot codes on file makes it possible to act on one.
Common misunderstandings
- “It must have an FDA clearance number.” Class I, 510(k)-exempt devices have none. See the classification above.
- “A standard number on a listing means certified.” ISO 11948-1 is a test method for absorption capacity; citing it is not a certification.
- “A bigger case is the same product.” Pack format varies by manufacturer and model, so check the specification sheet each time.
- “Wholesale means no questions asked.” Account terms are supplier policy and differ between sellers.
For other everyday supplies a buyer may add to the same order, see types of medical supplies and what underpads are.
FAQ
What should I verify before placing a first order?
Match the manufacturer or distributor wording on the label and invoice (21 CFR 801.1), match the product to the manufacturer’s specification sheet, and reconcile pack counts. Do not treat “FDA approved” as a document.
What documents should I ask the seller for?
The specification sheet, the test method behind any absorbency figure, the maker’s name and address, a complaint or return contact, and storage and lot-coding information. These are buyer practice, not a legal checklist.
What is the typical case or pack size and unit of measure?
It varies by manufacturer and model. Convert every quote to total units (units per bag times bags per case times cases) before comparing.
Can small buyers or new businesses open an account?
That is set by each supplier. Ask for its account requirements and any minimum order in writing.
What shelf life and lot information should be on the label?
21 CFR 876.5920 sets no date requirement; the manufacturer sets its own coding. Ask for its storage conditions and code format, and check that case and inner bag codes match.
