Amazon cross-border consignment is a common cross-border e-commerce model, which generally refers to individuals or enterprises selling goods on the Amazon platform abroad and consigning them to other countries or regions.

From a legal point of view, whether Amazon cross-border consignment is legal depends mainly on the laws and regulations of the relevant countries or regions. Different countries and regions have different regulations on cross-border e-commerce. Some countries and regions have stricter supervision on cross-border e-commerce, while others are more relaxed.

In China, the development of cross-border e-commerce also faces regulatory challenges. The relevant departments are increasingly strict in regulating and managing cross-border e-commerce to protect the rights and interests of consumers and maintain market order. In order to legally operate cross-border e-commerce business, enterprises need to comply with relevant laws, regulations and policies, such as the "E-Commerce Law of the People's Republic of China", "Customs Law of the People's Republic of China", "Consumer Rights Protection Law of the People's Republic of China", etc.

In summary, Amazon cross-border consignment itself is not illegal, but whether it is legal needs to be determined according to the laws and regulations of relevant countries and regions. For goods sold cross-border from outside China, it is necessary to comply with Chinese laws and regulations and relevant customs regulations, otherwise there may be administrative and legal risks.
