Temu and AliExpress both connect global buyers with affordable products from mainly Chinese suppliers, but they differ in focus and suitability for businesses. AliExpress is a long-established B2C and small wholesale platform under Alibaba, offering a huge product range, flexible order quantities, and international seller options, making it ideal for dropshipping and small to medium businesses. Temu, backed by Pinduoduo, is newer and emphasizes ultra-low consumer prices, fast shipping to the U.S. and select regions, and heavy marketing promotions, which makes it more attractive for direct shoppers than for resellers. For businesses, AliExpress generally provides broader supplier choice, better scalability, and integration with e-commerce tools, while Temu is more suited for bargain-hunting end customers rather than long-term sourcing.
