How to find the HS code for adapter (Swiss tariff)
Adapter classification depends on material (cast iron, steel, stainless steel, nickel), construction method (cast, welded, threaded) and application. The precise 8-digit Swiss tariff number – the customs tariff number – is determined by these factors.

What determines the tariff number?
- Material composition. Adapters made from cast iron, unalloyed steel and nickel are classified differently from stainless steel or pure nickel versions. Material selection drives multiple tariff code levels.
- Manufacturing process. Cast adapters differ tariffically from welded or threaded fittings. The production method (cast, welded, forged) is a central classification factor that impacts the final code.
- Form and function. Elbows, bends, sleeves, flanges and coupling pieces receive distinct classifications. The adapter's specific role in the pipe system determines precise tariff positioning.
Frequently asked questions
How do I find the correct HS code for my adapter?
Use our free Zolli classification tool. Enter the material, construction type and function of your adapter – the system automatically determines the 8-digit Swiss tariff number based on official nomenclature.
What happens if I declare the wrong HS code?
Incorrect classification can cause customs clearance delays, additional inspections or penalties. Accurate declaration is therefore critical.
Is the Swiss tariff number the same as the international HS code?
No. Switzerland uses an 8-digit system (Tarifnummer) based on the 6-digit international HS code, with national modifications and additional detail levels.
Is the classification tool free to use?
Yes, our classification tool is completely free. However, the result is advisory only and not a binding customs tariff ruling.
