Whether the rookie station supports the collection of a commodity is determined by the category of the commodity, which may be a large category or a sub-category. At present, I found that the categories of goods that do not support mail receiving service are: building materials (large category), decoration (large category), intelligent equipment (large category) and fitness equipment (small category). If such goods are included when placing an order, the modern delivery address option will not be provided. A few examples: door and window sealing strips, faucet bubblers, handles, and mi band wristbands. These three commodities are small in size and safe to transport and store, but they do not support building materials, home improvement, fitness equipment and intelligent equipment to receive goods. Taobao's product category tree is very complicated, and you can see it when you release the baby.
