Legal analysis: This depends on the situation. There is a type called commissioned production. If the other party knows that your trademark will be affixed to the product after it is processed, it will be fine. But there is another way to purchase other people's goods and put your own brand on them without permission. This is illegal and infringes on other people's registered trademark rights. According to the provisions of the Trademark Law, any one of the following acts shall constitute an infringement of the exclusive right to use a registered trademark:

(1) Using the same or similar goods on the same or similar goods without the permission of the trademark registrant; Registering trademarks with the same or similar trademarks;

(2) Selling goods that infringe the exclusive rights of registered trademarks;

(3) Counterfeiting, making without authorization or selling counterfeit trademarks registered by others , making a registered trademark mark without authorization;

(4) Changing the registered trademark without the consent of the trademark registrant and putting the goods with the changed trademark back into the market;

( 5) Causing other damage to the exclusive right to use registered trademarks of others.
