Scope in Google Analytics’ Custom Dimensions refers to how the value in the Custom Dimension is extended to all hits in the same scope.

Hit- and product-scoped Custom Dimensions apply to the given hit alone - they are not extended to any other hits in the session or by the same user.

Session-scoped Custom Dimensions apply the last value sent during the session to all the hits in that session.

User-scoped Custom Dimensions apply the last value set during the session to all the hits in the session AND to all future hits by the same client until a new value is sent.
