What are the products that are prohibited to sell on Facebook or whose sale is restricted?
To check whether a product may be offered for sale on Facebook, read Meta’s current Commerce Policies, including the prohibited and restricted content sections. These policies cover services designed for commerce, including Facebook and Instagram Shops; they are not limited to an old Page shop tab.
Also check the commerce eligibility requirements. To run an ad, Meta’s Advertising Standards also apply. Importing a product with the module does not authorize its sale or advertising.
