Kernrechtsfrage
Whether PET bottles returned against deposit and recycled after one use are 'Mehrweggebinde' under Art. 14 Ziff. 21 MWSTV.
Extrahierter Entscheid
Yes. The bottles fall under the reusable-container exemption because the deposit/pfand is the defining feature, even if the containers are used only once before recycling.
Extrahierte Begründung
The wording, context, purpose, and later legislation show that the special rule is meant to simplify VAT treatment of deposit containers. Treating these bottles as ordinary packaging would empty Art. 27 Abs. 2 MWSTV of content.
