Frequently asked questions
I manufacture steel chains for lifting and mooring: is ATECO code 25.93.20 correct?
Yes, 25.93.20 covers the manufacture of chains, with one clear exclusion: transmission chains do not belong here. Because they are mechanical power-transmission components, they fall under 28.15.00.
I make chains starting from metal wire — do I need a different code from 25.93.20?
No, the chain stays within 25.93.20 even if you form it yourself from wire. If the end product is a mesh, a cable, or a nail, however, you fall under 25.93.10.
I manufacture roller chains for transmitting motion in machinery — does 25.93.20 still apply?
No. Transmission chains are explicitly excluded from 25.93.20 because they are mechanical power-transmission components; they belong in 28.15.00. Code 25.93.20 covers lifting, mooring, safety, and general-purpose chains.
I make both chains and leaf springs in the same facility — can I use a single code within class 25.93?
No, they are two separate codes even though they are close. Non-transmission chains fall under 25.93.20, while leaf, coil, and torsion springs have their own entry at 25.93.30. Register the predominant activity as your primary code and the other as secondary.
