33 Repair, maintenance and installation of machinery and equipment

Contains 2 narrower codes

What 33 includes

This division covers specialized repairs of machinery, equipment, and products manufactured by industrial plants, the purpose of which is to restore operational efficiency, as well as general and routine maintenance (i.e., servicing), ensuring the efficient operation of equipment and preventing breakdowns and repairs.
This division covers only specialized repairs and maintenance. A significant number of repairs are performed by manufacturers of machinery, equipment, and other products. In such cases, the classification of a given economic entity engaged in combined repair and production is based on the principle of predominant value added, often resulting in these activities being combined as the production of a product.
The same principle applies to the combination of trade and repair. The rebuilding and reconstruction of machinery and equipment is treated as a manufacturing activity covered by other divisions of this division.
This division also includes specialized machinery installation.

What 33 excludes

Cleaning of industrial machinery, classified in 81.22.B,
Installing equipment that is an integral part of a building or similar structure (for example, installing electrical wiring, escalators, or air conditioning systems, classified in the appropriate subclasses of section F "Construction"),
Repair and maintenance of computers and (tele)communications equipment, classified in 95.10.Z,
Repair and maintenance of household goods, classified in the appropriate subclasses of group 95.2,
Repair and maintenance of products that are used both as means of production and as consumer goods, typically classified as repair and maintenance of household goods (for example, repair of office and home furniture) in 95.24.Z,
Repair and maintenance of motor vehicles and motorcycles, classified in the appropriate subclasses of group 95.3.
