An importer brings in vegetable oil intended for paint manufacture and pays a reduced rate of duty – the customs preference code in the declaration is what substantiates that claim. It is a numeric key taken from the Swiss Tares tariff database indicating on which legal basis and for which end use a product is assessed at a reduced rather than the standard rate. The code is tied to the tariff heading: the same commodity may attract different codes, and therefore different rates, depending on whether it is destined for industrial processing, animal feed or a technical application. From 1 November 2026 it must be stated in Switzerland together with assessment type "5 customs relief" and the business partner ID of the holder of the end-use undertaking. Not to be confused with the preferential origin code used under free trade agreements.
