AliExpress is a cross-border e-commerce platform where sellers can open stores and sell products in multiple countries around the world. When opening a store and selling on AliExpress, there are certain differences in pricing strategies in different countries:

1. Mainland China: Products in the Chinese market involve a lot of homogeneous competition, and price competition is relatively fierce. It is recommended to determine a sales price that can balance the profit margin based on the product gross profit margin. Generally speaking, it is enough to keep the price the same as or slightly lower than that of mainstream e-commerce platforms.

2. The United States and Canada: The North American market has high requirements for product quality and brand, and consumers are also more price-receptive, so the sales price can be appropriately increased. When pricing, you should consider costs such as shipping costs, taxes, and platform commissions. It is recommended to set prices based on a gross profit margin of 30-50%.

3. Major European countries: Consumers in mainstream European countries also have a certain brand and quality awareness, but due to the high import tariffs on products, it is necessary to consider the price acceptability to local consumers. Generally speaking, it is more appropriate to set prices based on a gross profit margin of 30-40%. Exchange rate factors should also be considered for different countries.

4. Australia and New Zealand: The pricing in the Australian and New Zealand markets should take into account factors such as the product delivery duty paid (DDP) price, the platform commission rate, and the local consumer price index. Since the two countries have low import tariffs on Chinese products, the pricing can be relatively high, and it is reasonable to control the gross profit margin at 35-45%.

5. Southeast Asia and other emerging markets: These markets have low consumption power and high price sensitivity. It is recommended to adopt lower pricing and control the gross profit margin at around 20-30%. Freight and taxes should also be considered when pricing to avoid compressing profit margins.

In summary, AliExpress's pricing strategies in different countries need to consider many factors, mainly including local consumer acceptance, the intensity of competition, import tariff rates, exchange rates, and platform fees. Reasonable pricing can satisfy consumers while also ensuring the profits of merchants, which requires sellers to conduct market research and calculations before opening a store.
