Article 3 of the Trademark Law stipulates that "a trademark approved and registered by the Trademark Office is a registered trademark, including a commodity trademark, a service trademark, a collective trademark and a certification trademark", which can be understood as a trademark used by a product produced by an enterprise (circulated as a commodity) and a commodity sold by an enterprise as a service trademark, and the two cannot replace each other. It should be said that it is possible for a sales enterprise to add its own service trademark to the goods it sells to show that the goods are distributed by the sales enterprise, but it cannot replace the commodity trademark. If a distributor replaces a commodity trademark with its own goods without the consent of the producer, it violates the fifth paragraph of Article 57 of the Trademark Law, that is, "changing its registered trademark without the consent of the trademark registrant and putting the goods with changed trademarks on the market again", which constitutes trademark infringement. If there is an agreement between the distributor and the manufacturer, the goods produced by the manufacturer shall be exclusively handled by the distributor, and the trademark of the distributor shall be regarded as the trademark of the goods. The label of a commodity shall indicate the words produced by the production enterprise and supervised by the company (distributor).
