NAICS Code for Electrical Supply Wholesaler
The NAICS code for an electrical supply wholesaler is 423610, Electrical Apparatus and Equipment, Wiring Supplies, and Related Equipment Merchant Wholesalers. It covers wholesale distributors of electrical apparatus and power distribution equipment: transformers, switchboards, panelboards, circuit breakers, unit substations, generators, motors, wire and cable, conduit, lighting fixtures and wiring supplies. On a federal supply contract, though, the agency uses the manufacturing code for the item (for example 335311 for transformers), not 423610. To bid on a small business set-aside as a reseller, you have to meet the nonmanufacturer rule: 500 or fewer employees, and generally supplying a small business manufacturer's U.S.-made product (13 CFR 121.402 and 121.406).
Related codes to add
Most businesses list several NAICS codes. Use 423610 as your primary if it covers most of your revenue, and add these when they describe work you also do:
| Code | Use it when | Size standard |
|---|---|---|
| 423690 Other Electronic Parts and Equipment Merchant Wholesalers | You mainly sell electronic parts or communications equipment, like circuit boards, radios or telephone systems. | 250 employees or fewer |
| 335311 Power, Distribution, and Specialty Transformer Manufacturing | You make power, distribution or specialty transformers yourself. | 800 employees or fewer |
| 335313 Switchgear and Switchboard Apparatus Manufacturing | You make switchgear or switchboard apparatus yourself. | 1,250 employees or fewer |
| 238210 Electrical Contractors and Other Wiring Installation Contractors | You also install what you sell, as an electrical contractor. | $19 million or less in receipts |
How to choose
Your primary NAICS code should match the work that brings in most of your revenue, and it sets which size standard applies to you for most set-aside contracts. Read each code's Census definition before you register. Our guide on how to choose NAICS codes covers the trade-offs.
