NAICS 333310

Overview

NAICS 333310 covers establishments primarily engaged in manufacturing commercial and service-industry machinery used in restaurants, institutional kitchens, laundries, dry-cleaning operations, vending, and related service venues. Typical products include commercial cooking and dishwashing equipment, washer-extractors and tumblers, dry-cleaning machines, vending machines, vehicle wash systems, and identifiable parts and attachments. Equipment is built for non-household, heavy-duty, continuous, or high-volume use in business and institutional settings. Federal buyers encounter this code for outfitting dining facilities, commissaries, medical and correctional institutions, and on-premises laundry operations. Installation/startup may be provided when incidental to manufactured end items, but the core activity is manufacturing of commercial and service-industry machinery as defined by NAICS. ¹

What this NAICS covers

• Manufacturing commercial kitchen and food-service machinery for non-household use (e.g., ranges, ovens, fryers, grills, steamers, kettles, warming/holding/proofing cabinets) for institutional and restaurant environments. ¹
• Manufacturing commercial warewashing equipment, such as conveyor/flight-type, door-type, and undercounter dishwashers; glasswashers; and related sanitizing/cleaning machines. ¹
• Manufacturing commercial laundry and dry-cleaning machinery, including washer-extractors, tumblers/dryers, flatwork ironers, presses, folders, spotting units, and dry-cleaning machines used in on-premises and self-service facilities. ¹
• Manufacturing automatic merchandising (vending) machines and systems, including coin-, bill-, or card-operated snack and beverage machines and integrated payment/dispensing mechanisms. ¹
• Manufacturing vehicle wash machinery, including coin-operated and automatic car-wash systems (in-bay rollover, tunnel/conveyor, self-serve) and integral sprayers/blowers supplied as part of the system. ¹
• Manufacturing parts, subassemblies, and attachments for the above machinery when produced for incorporation into, or as identifiable replacements for, such equipment. ¹
• Establishments classified in NAICS 333310 may produce multiple product lines across these categories, provided the focus remains on commercial- and institutional-grade machinery rather than household appliances. ¹

Frequently asked questions

• Question: What kinds of equipment fall under NAICS 333310? Answer: It covers commercial food-service cookline and warewashing equipment, commercial laundry and dry-cleaning machinery, automatic merchandising (vending) machines, vehicle wash systems, and identifiable parts/attachments intended for these machines, all designed for non-household, heavy-duty use in institutional and service settings. ¹

• Question: How is NAICS 333310 different from household appliance manufacturing? Answer: Household appliances such as residential ranges, refrigerators, and dishwashers fall under NAICS 335220. NAICS 333310 focuses on non-household, commercial/service-industry machinery built for institutional or restaurant environments and continuous duty cycles, not consumer-use appliances. ⁴

• Question: Does NAICS 333310 include commercial refrigeration and ice machines? Answer: Generally no. Institutional/commercial refrigeration and ice-making equipment are typically classified under NAICS 333415. These products are often co-procured with kitchen equipment but are categorized separately from commercial and service-industry machinery. ²

• Question: Are vending machines classified in NAICS 333310? Answer: Yes. Manufacturing of automatic merchandising (vending) machines is included in NAICS 333310. However, companies that operate vending machines as a retail service are classified under NAICS 459210, not in manufacturing. ⁷

• Question: Do installation and startup services affect classification under NAICS 333310? Answer: Manufacturers may provide installation/startup when incidental to the sale of equipment and remain classified in manufacturing. If an award is primarily for non-incidental repair or maintenance of existing equipment, use NAICS 811310 for services. ⁶
