Local Laws Overview

- Consumer protection and unfair practices: The Luxembourg Consumer Code prohibits misleading and aggressive commercial practices and sets rules on transparency, clear advertising identification, and fair terms. Comparative advertising is permitted if it is objective, verifiable, and non-deceptive.

- Pricing and promotions: Advertised prices must be clear, final, and include VAT and mandatory fees. Price reductions must be genuine and based on verifiable prior prices. Promotions and loyalty offers must not mislead and must display key conditions and limitations.

- Giveaways, contests, and games: Promotional games are allowed if structured to avoid being an illegal lottery. As a rule, avoid any requirement to pay to participate, publish clear rules, ensure random draw or skill criteria are fair, and comply with data protection and publicity obligations. Prizes must be awarded as promised.

- Influencer and native advertising: Advertising must be clearly identifiable. Influencer content with any form of consideration or benefit should be labeled as advertising in a clear and immediate way. Hidden advertising is prohibited in both online and audiovisual media.

- Data and direct marketing: GDPR applies to all personal data processing. For email and SMS marketing to natural persons, prior opt-in consent is generally required, with a simple unsubscribe. Business-to-business communications may be subject to different rules but must respect legitimate interests and opt-outs. Cookies and trackers used for advertising typically require prior consent, and you must provide a transparent cookie notice and an easy way to withdraw consent.

- Audiovisual and online platforms: Audiovisual commercial communications are supervised for advertising identification, sponsorship transparency, product placement rules, and protection of minors. Online platforms and video-sharing services must protect minors and restrict certain product advertising around youth content.

- Sector-specific regimes: Alcohol, tobacco, gambling, medicines, medical devices, financial services, and insurance have stricter marketing rules. For example, tobacco advertising is broadly prohibited, alcohol marketing must not target minors or encourage excessive consumption, prescription medicines may not be advertised to the public, and financial promotions must be fair, clear, and not misleading under financial and insurance supervision rules.

- Environmental and sustainability claims: Green claims must be truthful and substantiated with robust and current evidence. Avoid vague or absolute statements like environmentally friendly unless you can substantiate the full life-cycle impact. Comparative environmental claims must be accurate and verifiable.

- Language and clarity: There is no single mandatory language for advertising, but consumer information must be clear and understandable. In practice, French and German are commonly used in Luxembourg. Ensure key terms, prices, and conditions are prominent and easy to read.

- Local signage in Differdange: Outdoor advertising, shopfront signs, awnings, flags, and illuminated signs generally require prior authorization from the Commune of Differdange. Location, size, illumination, and aesthetic integration are assessed under local urban planning rules. Roadside signs may also require approval from the national roads authority where applicable. Unauthorized installations can lead to removal orders and fines.

- Enforcement and complaints: Consumer authorities can investigate and order cessation of unlawful practices. The audiovisual regulator oversees commercial communications in media and may issue sanctions. The data protection authority enforces GDPR obligations related to marketing and cookies. Courts can grant injunctions, award damages, or require corrective statements.
