The semi-hosted delivery model of AliExpress does have certain requirements for the packaging dimensions of goods. According to the standard logistics regulations of AliExpress, the packaging dimensions of goods are divided into two billing methods: small packages and large packages. Small packages are applicable to packages with a weight not exceeding 2kg, a single side not exceeding 60cm, and a length + width + height not exceeding 90cm; while large packages are applicable to packages with a weight exceeding 2kg, or a single side exceeding 60cm, or a length + width + height exceeding 90cm.

In addition, the AliExpress platform also requires merchants to follow certain standards and processes during the delivery process to ensure the safety and timely arrival of goods. This includes shipping according to the time nodes specified by the platform, choosing logistics channels that meet the requirements of the platform, filling in accurate shipping information, and packaging according to the packaging standards specified by the platform.

For AliExpress semi-hosted JIT products, the platform also controls the unit weight of the goods. Merchants need to accurately fill in the system vendor and product SKU unit weight information to ensure that it is filled in truthfully and accurately, and meets the platform requirements in terms of weight and size.

Therefore, in order to ensure smooth transportation and avoid additional costs, sellers are advised to carefully check the size and weight of the package before shipment to ensure that it meets the standard requirements of AliExpress. At the same time, it is also necessary to pay attention to the policy changes and updates of the platform and adapt to these changes in a timely manner to ensure a smooth and efficient delivery process.
