Frequently asked questions
I install measuring instruments, process control systems and industrial weighing equipment — is that ATECO code 33.20.03?
Yes. 33.20.03 covers the installation of measuring, testing, navigation and control instruments and apparatus, the assembly of industrial process control equipment, and the installation of industrial weighing apparatus.
What is the difference between installing an instrument (33.20.03) and manufacturing it?
33.20.03 covers assembling and commissioning the instrument at the client's site; manufacturing it falls under the relevant production code, for example other measuring and testing instruments in 26.51.29.
If I install both measuring instruments and communications equipment, which codes apply?
These are two distinct headings within the same class. Measuring and control instruments fall under 33.20.03; communications and broadcasting equipment falls under 33.20.02. Use the code for your predominant activity as primary and the other as secondary.
