Which code does this activity belong in?
NAICS 33361 covers establishments that manufacture engines, turbines, and power transmission equipment as primary products. The key distinction from neighbouring codes is that 33361 focuses on these components themselves, whereas establishments manufacturing complete machinery systems that incorporate engines or turbines as integrated parts belong in other categories. For example, manufacturers of farm machinery or construction equipment that include engines as components are classified in Agriculture, Construction, and Mining Machinery Manufacturing, not in 33361. Similarly, establishments making pumps, compressors, or material handling equipment are classified in Other General Purpose Machinery Manufacturing rather than 33361.
