The clarification addresses a practical implementation question of the post-Brexit trade regime between Switzerland and Great Britain: the treatment of pre-materials of EU origin in cumulation calculations. For exporters and customs authorities, the clarification is relevant in order to reduce classification uncertainties and minimize trade friction.

Detailed Summary

The circular amendment clarifies the cumulation rules in the Switzerland-UK Free Trade Agreement, in particular the question of how pre-materials of EU origin are taken into account in determining origin. This is a technical but practically significant trade regulation, since cumulation allows companies to combine materials from several countries (here: Switzerland, UK, EU) and still claim preferential tariff treatment.

The information sheet "Brexit – Cumulation Options" was adjusted as a guidance tool to ensure consistency between the circular and the practical guide. The BAZG is available for inquiries at [email protected].
