Automatic summary, not yet reviewed

The bill would amend the General Law for the Defense of Consumers and Users to prevent shrinkflation, which is when a product gets smaller in size or quantity while its price stays the same or goes up.
The bill proposes adding a paragraph to Article 20 of that law. If a prepackaged product drops in quantity and that raises its price per unit of measure, with the same or similar packaging, sellers would have to clearly inform buyers.
The notice would have to be posted at the point of sale, legibly and visibly, for at least 90 days from the first sale of the product with its new features.
If passed, the law would take effect the day after its publication in the Official State Gazette (Boletín Oficial del Estado).

Who it affects

Consumers: Would receive a clear notice when a prepackaged product contains less quantity and its price per unit goes up.
Companies selling prepackaged products: Would have to report the quantity reduction at the point of sale for at least 90 days.
Retailers and distributors: Would have to display the notice legibly and visibly at the final point of sale.
