Does the 30-Day Price Rule Apply in Luxembourg?

Yes. The 30-day price rule applies in Luxembourg, because it comes from the EU Omnibus Directive, (EU) 2019/2161, which has applied across the Union since 28 May 2022 and is transposed into Luxembourg’s national law. If you announce a price reduction to Luxembourg customers, the rule is in play.

What the rule requires

When you advertise that a product’s price has been reduced, you must state the prior price — and that prior price is the lowest price you applied for the item in the 30 days before the reduction. The purpose is to prevent a price being nudged up for a short spell so a later “discount” looks more generous than it really is.

What this means for your shop

• Keep a price history so you can show the lowest price of the previous 30 days for any reduced item.
• Show that prior price alongside the sale price, in the languages your Luxembourg customers read.
• Remember Luxembourg is multilingual — French, German and Luxembourgish are all in everyday use.

The rule is the same across the Union, since it flows from the Omnibus Directive; Luxembourg adds the national implementing law, supervision by the responsible ministry and consumer bodies such as the ULC, and its multilingual market. For the wider picture, see our complete Omnibus guide.
