When to use a different code
Census classifies these close-sounding activities somewhere else. Businesses mainly engaged in:
- Manufacturing drilling and underground mining machinery and equipment are classified in Industry 33313, Mining and Oil and Gas Field Machinery Manufacturing.
- Manufacturing industrial plant overhead traveling cranes and hoists, truck-type cranes and hoists, winches, aerial work platforms, and automotive wrecker hoists are classified in Industry 33392, Material Handling Equipment Manufacturing.
- Manufacturing rail layers, ballast distributors, and other railroad track-laying equipment are classified in Industry 336510, Railroad Rolling Stock Manufacturing.
