Frequently asked questions
I manufacture coil springs and leaf springs for vehicles: is ATECO code 25.93.30 correct?
Yes, 25.93.30 covers leaf springs, coil springs, torsion bars, and spring leaves. One precise exception applies: clock springs do not belong here — they follow the manufacture of watches and clocks at 26.52.00.
I make springs from metal wire — should I use the wire products code or 25.93.30?
Use 25.93.30, because what matters is the finished product. The spring stays here even if you start from wire; wire products such as meshes and nails are classified instead under 25.93.10.
I manufacture small springs for watches and precision mechanisms: code 25.93.30 or watchmaking?
No, clock and watch springs are excluded from 25.93.30 and follow the watchmaking classification at 26.52.00. Code 25.93.30 covers industrial and vehicle springs such as leaf and coil springs.
I make springs but also steel chains in the same workshop — can I use the same code within class 25.93?
No, they are two separate entries. Leaf, coil, and torsion springs belong in 25.93.30; non-transmission chains have their own entry at 25.93.20. Use the predominant activity as your primary code.
