How do Wholesaler, Retailer compare side by side?
The table below compares Wholesaler, Retailer across 10 procurement-relevant dimensions, from position in the chain through source.
Side-by-side comparison
| Dimension | Wholesaler | Retailer |
|---|---|---|
| Position in the chain | FDA lists the "wholesale distributor that is not a manufacturer or importer" as its own role, separate from manufacturers and importers. | Per 21 CFR 807.65(e): pharmacies, surgical supply outlets or similar retail establishments "making final delivery or sale to the ultimate user". |
| FDA device establishment registration | No registration, no device listing, no registration fee for a wholesale distributor that is not a manufacturer or importer (FDA, Who Must Register, List and Pay the Fee). | Exempt from establishment registration under 21 CFR 807.65(e). |
| Buying a device and selling it under its own name | Putting your own name on a device is a manufacturer or relabeler question, not a wholesaler one, so ask the seller who the manufacturer of record is. | The 807.65(e) exemption also covers a pharmacy or similar retail establishment that buys a device for distribution under its own name, for example a label reading "distributed by" or "manufactured for" that retailer. |
| Dispensing to the consumer | Dispensing to the consumer is the retail-side activity the rule describes. | 21 CFR 807.65(i) also exempts persons who dispense devices to the ultimate consumer, for example a hearing aid dispenser or optician. |
| When the exemption stops applying: importing | An initial importer must register and pay the fee but does not list; an import agent or broker that does not take first possession is not required to register (FDA). A wholesaler that imports is in the importer category. | The 807.65(e) exemption is for final delivery or sale to the ultimate user. A retail outlet that itself imports or manufactures should check FDA's registration table for that activity. |
| Drugs instead of devices | Drug wholesaling has separate FDA and state licensure under the Drug Supply Chain Security Act. See <a href='/guides/pharmaceutical-wholesaler'>pharmaceutical wholesaler</a> and <a href='/dictionary/term/dscsa-compliance-requirements-for-distributors'>DSCSA distributor requirements</a>. | The device exemptions above do not make a drug sale a device sale. Confirm whether the product is a drug or a device before relying on either column. |
| Wholesaler vs reseller | The FDA registration guidance addresses the wholesale distributor role; resale is a separate paperwork question. The resale paperwork question is covered in <a href='/guides/resale-certificate-for-medical-supply-distributors'>resale certificates for medical supply distributors</a>. | A retailer is the final sale to the ultimate user under 21 CFR 807.65(e). |
| What to ask a seller or buyer to confirm | Which role they hold (distributor, importer, manufacturer), who the manufacturer of record is, whether the product is a drug or a device, and any documents your organisation requires. | Whether the retail outlet is the final seller to the user, and whether the label shows another name ("distributed by" or "manufactured for"). |
| When to pick each | Pick a wholesaler relationship when you are supplying an organisation or reselling onward and need to confirm role and product class. See the <a href='/guides/medical-supply-wholesaler'>medical supply wholesaler guide</a>. | Pick a retailer when you are the ultimate user of the device, or when you are the outlet making that final sale. |

Common questions
Common questions about Wholesaler vs Retailer
What is the difference between the options in "wholesaler vs retailer"?
+
A retailer makes the final delivery or sale to the ultimate user; FDA's rule on device registration exemptions names pharmacies, surgical supply outlets and similar retail establishments doing exactly that (21 CFR 807.65(e)). A wholesaler sits earlier in the chain; FDA lists the wholesale distributor that is not a manufacturer or importer as a separate role. For the wholesaler vs reseller variant, resale paperwork is a separate question from FDA registration.
Which is the better fit for a medical supply seller or buyer?
+
It depends on who you are. An individual end user buys from a retailer. An organisation that resupplies itself or sells onward deals with a wholesaler. Whichever you choose, confirm the seller's role (distributor, importer, manufacturer), the manufacturer of record, and whether the product is a drug or a device.
What legal or compliance risks differ between them?
+
For devices, neither a wholesale distributor (that is not a manufacturer or importer) nor a retail outlet selling to the ultimate user must register with FDA. The risk is the role changing: a company that manufactures, relabels or imports leaves the exemption, and an initial importer must register and pay the fee. For drugs, wholesale distribution has its own FDA and state licensure under the DSCSA. This is general information, not legal advice.
