How to find the HS code for relay (Swiss tariff)
The classification of a relay depends on its switching mechanism, contact material, voltage class, and intended use. Your exact HS code and Swiss customs tariff number are determined by these factors.

What determines the tariff number?
- Switching mechanism. Electronic relays with semiconductor-based triggering are classified differently from electromechanical relays with moving contacts. The construction type is a key differentiator.
- Contact material. Relays with precious metal contacts – silver, platinum, or gold-plated – follow different classification rules than those with standard metal contacts.
- Voltage class and power rating. Design for low voltage, high voltage, or high-frequency operation affects the HS code. Maximum switching capacity is also a relevant classification criterion.
- Intended use. Relays for general control applications are classified differently from specialized relays for aircraft systems or ordnance triggering devices. The end-use purpose matters.

Frequently asked questions
How do I find the correct HS code for my relay?
Use our free classification tool. Enter the technical specifications – switching mechanism, contact material, voltage class, and intended use – and receive your Swiss customs tariff number instantly.
What happens if I declare the wrong HS code?
Incorrect classification can cause delays in customs clearance and incur additional costs. It is essential to determine the correct code before importing.
Are permits required for importing relays?
Certain specialized relays – such as those for ordnance triggering in aircraft – may require permits from SECO. Check with the competent authorities for your specific product.
Is the classification with your tool free?
Yes, our classification tool is completely free. Results are advisory and do not constitute a binding customs tariff ruling.
