Wound Care Suppliers: How to Vet a Source for Dressings

Wound care suppliers explained: which roles must register with FDA, which dressings are Class I, and what to ask a supplier for.

Short answer

A wound care supplier can be a manufacturer, an importer, a relabeler or a distributor, and FDA treats those roles differently. Manufacturers, initial importers and relabelers or repackagers must register their establishments, while a wholesale distributor that is neither is marked “no” on FDA’s registration chart. So vet the manufacturer behind the product as well as the seller.

Definition and scope

“Wound care suppliers” in this guide means the businesses that sell dressings and related wound-care products to clinics, facilities and other buyers. For what the products are, see what a medical dressing is. For ordering in volume, see wound care supply wholesale buying; this page covers the earlier question of who you are buying from; how to find wholesale suppliers covers sourcing in general.

How supplier roles map to FDA registration

FDA’s page “Who Must Register, List and Pay the Fee” separates roles in a registration chart. The rows below follow that chart and its definitions (checked 2026-11-01).

Supplier role Must register with FDA? What the page says
Manufacturer (including kit assemblers) Yes Listed as a registering role.
Initial importer Yes Must have a physical address in the United States.
Relabeler or repackager Yes A relabeler changes the labeling supplied by the original manufacturer for distribution under its own name; a repackager packages finished devices from bulk.
Specification developer Yes Listed as a registering role.
Domestic distributor that does not import devices No Listed as not required to register.
Wholesale distributor that is not a manufacturer or importer No Listed as not required to register.

The practical consequence is that a distributor’s own registration status tells you little. The identity of the manufacturer, importer or relabeler named on the product label is the more useful thing to ask a distributor for.

What FDA class common dressings are in

Two federal regulations cover plain dressings (eCFR text checked 2026-11-01):

  • 21 CFR 878.4018, hydrophilic wound dressing: a sterile or non-sterile device intended to cover a wound and absorb exudate. Class I (general controls), exempt from premarket notification subject to the limitations in 878.9.
  • 21 CFR 878.4020, occlusive wound dressing: a nonresorbable device that covers a wound, provides or supports a moist wound environment and allows exchange of gases such as oxygen and water vapor, made of synthetic polymeric material such as polyurethane. Class I (general controls), exempt from premarket notification subject to 878.9.

Both regulations carve out dressings with added drugs such as antimicrobial agents, added biologics such as growth factors, or materials derived from animal sources. Those products are not in these classifications, so they need their own classification check. This matters when comparing products: for a plain absorbent or polyurethane dressing, a missing 510(k) number is not by itself a warning sign, because the class is exempt. For an antimicrobial or animal-derived dressing, ask the supplier for the product’s regulatory pathway. For type differences see hydrocolloid dressings and dressing vs bandage.

Documents and details to ask a supplier for

This checklist is drawn from the FDA pages cited above and is not an exhaustive procurement standard.

  1. The name of the manufacturer, and of any importer or relabeler, as it appears on the product labeling.
  2. Whether the seller is itself a manufacturer, importer, relabeler or repackager, or only a distributor (the registration chart treats these differently).
  3. For an importer, the United States address that FDA requires it to maintain.
  4. The product’s device classification and, where the product needed marketing authorization, its premarket submission number. FDA says device listings should carry that number where authorization is required (FDA, Device Registration and Listing).
  5. Lot and expiry information on the packaging; see does gauze expire for how dating works on sterile products.

When Medicare DMEPOS supplier standards apply

These rules matter only when a Medicare-billing DMEPOS supplier is involved, for example when a supplier bills Medicare for supplies. Under 42 CFR 424.57(c) (eCFR), such a supplier must be licensed where State law requires, must honor all warranties expressed and implied under applicable State law, must not contract with excluded entities, must meet DMEPOS quality standards and be separately accredited to enroll in and bill Medicare for each location, and is responsible for delivery and for maintaining proof of delivery. A facility buying dressings for its own use is not automatically subject to these standards.

Common misunderstandings

“Registered with FDA” is not “FDA approved”

FDA’s registration and listing pages describe establishment registration and device listing. They do not state that registration means a product is approved or cleared, so treat a registration number as identifying an establishment, not as a statement about the product.

Distributors are not on the registration chart

A wholesale distributor that does not manufacture or import is marked “no” on FDA’s chart, so a distributor having no registration is not unusual. It does mean the registration to look for belongs to the party upstream.

Every dressing needs a 510(k)

Not so for the two Class I categories above, which are exempt subject to 878.9.

Frequently asked questions

What is a wound care supplier?

A business that sells dressings and related wound-care products. Under FDA’s chart it may be a manufacturer, initial importer, relabeler or repackager, or a distributor, and only the first three must register their establishments.

Do medical supplies for wound care need FDA clearance?

It depends on the product. Hydrophilic (21 CFR 878.4018) and occlusive (878.4020) wound dressings are Class I and exempt from premarket notification, subject to 878.9. Dressings with added drugs, biologics or animal-derived materials fall outside those two regulations and need their own classification check.

Does a distributor have to be registered with FDA?

FDA’s chart lists a domestic distributor that does not import devices, and a wholesale distributor that is not a manufacturer or importer, as not required to register.
