This depends on where the dispute arises.

If the product does not match the seller’s sales description, it is a sales contract dispute. It is a sales contract dispute between consumers and sellers.

If the e-commerce platform charges consumers an appraisal fee, and the goods received by the consumer are inconsistent with the appraisal content, there will be a service contract dispute between the consumer and the e-commerce platform.

If the e-commerce platform charges the appraisal fee from the seller, and the consumer purchases the product from the seller, and the product does not match the sales description, there will still be a sales contract dispute between the consumer and the seller. The platform is not involved in the business of buying and selling goods. However, if the platform and the seller misrepresent the product and make false publicity, the platform and the seller shall bear joint and several liability for compensation.
