Do consumer rights rules apply to an online marketplace?
Short answer
Yes for what the marketplace itself states: ranking disclosure, review verification and price reduction claims sit with the platform even when the contract is with the seller.
Read against the registers 2026-08-26.
Who the role is
A platform where a third party sells to a buyer: the platform carries duties of its own, next to the seller's.
What the topic covers
The EU writes a detailed pre-contract information list, a withdrawal right and price display rules. The United States works mainly through unfair and deceptive practice enforcement, with state rules on top.
Duties the EU acts name for this role
- Consumer Rights Directive — Directive 2011/83/EU: Tell the buyer whether the counterparty is a trader or a private seller, and how duties are split with the platform.
- Omnibus Directive — Directive (EU) 2019/2161: Show the ranking parameters in the search result and mark paid placement as paid.

European Union

- Omnibus Directive — Directive (EU) 2019/2161: Adds duties on price reduction announcements, review verification and marketplace ranking disclosure.
- Price Indication Directive — Directive 98/6/EC: Selling price and unit price must be shown unambiguously to the consumer.
- Unfair Commercial Practices Directive — Directive 2005/29/EC: Prohibits misleading actions and omissions that change the average consumer's decision.
United States
- FTC Act Section 5, unfair or deceptive practices in AI and data: Section 5 covers deceptive pricing, fake reviews and unsubstantiated claims in the same commercial ground.

No Chinese row in our register for this topic. That is a gap in the register, not a statement that no rule exists.
Where companies usually start
- Check the price history behind every reduction claim before the campaign starts.
- Write one checkout information block and translate it, rather than one per market.
- Keep review verification evidence with the product, not with the marketing team.
