Frequently asked questions
I install industrial machinery, warehouse racking and commission production lines — is that ATECO code 33.20.09?
Yes. 33.20.09 covers the installation of industrial machinery on-site, the dismantling of large machinery, final commissioning, the positioning of heavy equipment, and the installation of racking and storage systems that are not integrated into the building.
I install standalone EV charging stations — is that ATECO code 33.20.09?
Yes, for the installation of a standalone charging station, which 33.20.09 explicitly lists among its activities. This should be distinguished from operating a charging point and selling electricity, which falls under 35.15.00, and from electrical wiring within a building, which falls under 43.21.01.
I install heat pumps and industrial refrigeration systems — is that 33.20.09 or a construction code?
Usually 33.20.09 if these are industrial units, since the code explicitly includes industrial refrigeration, freezing and heat-pump equipment. For heating and cooling plant serving a building as part of its infrastructure, the relevant construction code applies instead, such as 43.22.05.
