WPML

If you are using WPML, you almost surely felt the need to translate the badge applied to the product into any language users may display on your website.
The first step would be to translate the badge, as described in this page in the guide.

You will notice that, during the page translation process, you will be given the chance to select a new badge between those you have available for that specific language.

In case no badge is selected, the plugin will use the badge linked to the product in the original language.
