On the AliExpress platform, setting the weight of products is very simple. First, log in to your AliExpress account and go to the "My AliExpress" page.

Then, select "Product Management" and find the product whose weight you need to set.

Click on the product page to enter the edit mode and find the "Weight" option in the product details.

Enter the net weight of the product here, usually in kilograms. Make sure to enter an accurate weight for smooth shipping and calculation of logistics costs.

Finally, save the changes and update the product information.

At this point, the weight of the product has been successfully set and will be displayed on the purchase page to help buyers understand the actual weight of the product.
