A third party offering product information.
Often it can be difficult to collect product information data from an organization, therefore these third party suppliers exist to help those in need. For example, if a user needs data on all industrial supplies, there is a third party out there who can provide the user with what they are looking for. The suppliers often can deliver large volumes of high-quality data, which can also include product photos and descriptions. The more high-quality data available for the user, can lead to a more efficient PIM system.
