How-To
Navigate to Configuration -> Returns in your Rich-Returns dashboard.
There is a field for Excluded product-tags (optional):
Add the product tag of the affected product exactly as you have written it in your Shopify store for the product.
One product-tag per line (no comma in between).
A product tag consisting of multiple words goes on one line (Excluding items based on product tags: I have a tag with two words. How do I write it exactly?)
Think your product is still not being excluded? See our Playbook for non-matching product tags.
Result
The product will show up as "Not eligible for return" for the customer during the return process.
Tip: To prepare the customer for this situation and reduce support inquiries it makes sense to clearly communicate any excluded products and categories on your own returns-policy page.
Special Case: Route Insurance and 3rd party products
How do I make sure the Route Shipping Insurance (or other 3rd party products) can't be available for a return?
Products can only be excluded based on a product tag you assign to them in your Shopify dashboard. If there is no product tag because it is a product of a 3rd party app you need to check directly with their developers if there is an option to add a product tag from their side. After that add the product tag to our dashboard.
