Greetings @Seller_rsNdwKDHKSZbG,

Thanks for reaching out with your question regarding categories. Products are only allowed to have a single Category and Browse Node. At this time there is no way to add multiple categories or browse nodes to a single product. You should identify the single category that matches your product best as it is not permitted to have multiple. You can however include relevant information on the detail page or search terms. Thank you for your understanding.

-Glenn
