Installation of industrial machinery and equipment
What this code covers
Use this class for installation of industrial machinery and equipment when the main activity includes Installation of industrial machinery in industrial plant and Installation and assembly of industrial process control equipment. Check exclusions and nearby codes before applying it to a mixed activity.
Official NACE Rev. 2.1 labels and explanatory notes are imported from the source dataset. Plain-language explanations are shown separately so readers can compare interpretation with the source text.
No child codes; this is a class-level code.
- This class includes the specialised installation of machinery. However, the installation of equipment that forms an integral part of buildings or similar structures (for example, installation of escalators, electrical wiring, burglar-alarm systems or air-conditioning systems) is classified as construction.
- installation of industrial machinery in industrial plant
- installation and assembly of industrial process control equipment
- installation of other industrial equipment, e.g.:
- installation of charging facilities in wall-boxes, see section F
- construction of complete warehouses, see 41.00
- installation of elevators, escalators, automated doors, vacuum cleaning systems, etc., see 43.24
- installation of doors, staircases, shopfittings, furniture, etc., see 43.32
- Compare with 41.00, 43.24, 43.32 when the main activity overlaps another code.
- Check national equivalent caveats before using this code for local registration or filing workflows.
- If the main revenue activity appears in an exclusion, compare the alternative code before deciding.

What is NACE 33.20 used for?
Use NACE 33.20 for installation of industrial machinery and equipment when the main activity matches this scope: Use this class for installation of industrial machinery and equipment when the main activity includes Installation of industrial machinery in industrial plant and Installation and assembly of industrial process control equipment. Check exclusions and nearby codes before applying it to a mixed activity.
What are typical examples for 33.20?
Typical examples include Installation of industrial machinery in industrial plant, Installation and assembly of industrial process control equipment, and Installation of other industrial equipment.
When might 33.20 not be the right code?
Review another code when the activity is closer to installation of charging facilities in wall-boxes, see section F and construction of complete warehouses, see 41.00.
Which codes should I compare before choosing 33.20?
Compare 33.20 with 41.00 Construction of residential and non-residential buildings, 43.24 Other construction installation, and 43.32 Joinery installation when the activity description is ambiguous.
