To enter Amazon cross-border e-commerce, you first need to register an Amazon seller account, then choose a suitable sales plan and pay the corresponding fees.

Next, you need to prepare the products and create product listings, and then set appropriate prices and shipping costs.

In the initial stage, you can consider using Amazon advertising to increase the exposure of your products. At the same time, you must understand and comply with the relevant laws and regulations of cross-border e-commerce, and establish a good after-sales service and customer communication mechanism to enhance consumers' shopping experience.
