After purchasing a product on Alibaba, it is generally not possible to cancel the order directly.
Once a purchase is successful, the order is considered binding.
Orders that have been successfully paid for cannot be canceled. You can, however, apply for a refund. To do so:
On the desktop website:
Go to All orders and select "Apply for refund".
Alternatively, you can select "Request modification" and select "Apply for refund" in the Order details page.
On the app:
Go to My Alibaba >All orders and tap the order you wish to cancel. Tap "More actions" and then "Apply for refund".
Once you've applied for a refund, you're required to reach out to the supplier and attempt to resolve the case. If no resolution can be reached, the Alibaba.com team will step in to intervene.
