NAICS 336612

Overview

The North American Industry Classification System (NAICS) is the federal standard for organizing business establishments so statistical agencies can collect, analyze, and publish data on the U.S. economy. Developed cooperatively by the U.S. Economic Classification Policy Committee under OMB with Statistics Canada and Mexico’s INEGI, NAICS was adopted in 1997 to replace SIC and enable cross-country comparability. ¹
NAICS 336612 covers establishments primarily engaged in building boats—watercraft not built in shipyards and typically intended for personal or recreational use. Illustrative examples include inboard or outboard motorboats, rowboats, dinghies (except inflatable rubber), sailboats, and yachts not built in shipyards. Cross-references direct shipyard work to 336611 and inflatable or rubber boats to plastics and rubber manufacturing industries. ²

Frequently asked questions

• What activities does NAICS 336612 include?
  Boat building conducted outside shipyards, including inboard/outboard motorboats, rowboats, non-inflatable dinghies, sailboats, and yachts primarily for personal or recreational use. The definition distinguishes boats from shipyard-built vessels intended for commercial, military, or other non-personal uses. ²

• What activities are excluded from NAICS 336612?
  Work on large commercial or military vessels handled in shipyards is classified in NAICS 336611. Inflatable plastics boats are classified under NAICS 326199, and rubber boats or life rafts are classified under NAICS 326299. ²

• How is NAICS used in federal procurement systems?
  Contract opportunities on SAM.gov are tagged with NAICS codes, enabling agencies and vendors to filter, post, and analyze opportunities by industry classification. This supports market research, set-aside eligibility, and reporting across the federal acquisition lifecycle. ³

• Which PSC codes describe small boat purchases associated with NAICS 336612?
  PSC 1940 “Small Craft” covers powered and unpowered small craft, yachts, pneumatic boats, and lifesaving boats. Contracting officers select the PSC that best describes the specific product or service being acquired. ⁴

• Does NAICS 336612 specify allowable boat materials?
  Not specified by official sources. However, the NAICS cross-references place inflatable plastics boats in 326199 and rubber boats or life rafts in 326299, indicating that such inflatable or rubber craft are outside NAICS 336612. ²
