Pringles was subjected to a 17.5% VAT, a rate used for potato crisps and potato-derived snacks. P&G lawyers successfully contested this decision. Lawyers for Procter & Gamble argued that Pringles were not truly crisps, despite being labeled "Potato Crisps" on their container. It was argued that Pringles shape is not found in nature and that the potato content was only 42%.

Love they are proud if this fact!
(42% potato)
