How to find the HS code for O-ring (Swiss tariff)
The correct HS code and Swiss customs tariff number for O-rings depends on the material, intended sealing function, and packaging format. Vulcanised soft rubber seals fall into different classifications based on whether they are individual components, bundled sets, or part of multi-material seal assemblies.

What determines the tariff number?
- Material and vulcanisation grade. O-rings made from vulcanised soft rubber are classified differently from other rubber types. The vulcanisation process and material composition directly determine the tariff position.
- Sealing function and application. Whether the O-ring serves as a seal in machinery or is supplied as a standalone component affects classification. Dedicated seals and general rubber parts have distinct tariff positions.
- Packaging and delivery format. O-rings supplied individually, in sets, or bundled with different sealing materials may have different HS codes – particularly when offered as multi-material assortments or kits.
