Amazon's third agreement involves not selling counterfeit products on the Amazon platform without its explicit written consent. The key to solving this problem is: Comply with Amazon's intellectual property policy: avoid selling products that infringe trademarks or copyrights. Carefully review suppliers: purchase from reliable suppliers and require proof of product authenticity. Establish a clear reporting system: encourage buyers and suppliers to report any suspected counterfeiting. Cooperate with Amazon: take advantage of Amazon's brand registration function and report infringement tools to proactively prevent and respond to counterfeiting.
