Your product might be marked with an error “Compliance – Health & Wellness” and unpublished because products in certain categories must be pre-approved before becoming available. This policy specifically applies to products in Health & Wellness categories.
To resolve this issue, sellers should create a support case with the Walmart support team using the support categories: Items/Inventory > My item is unpublished. When requesting permission to sell unpublished products with this error, include a list of the brands or items you wish to sell. Sellers may request approval for all the products listed in this category, but approvals are usually granted for specific brands or items within these categories.
