Important: For trading card listings in Non-Sport Trading Card Singles (183050), CCG Individual Cards (183454), and Sports Trading Card Singles (261328) categories, Condition ID 2750 can be used to specify the card as a Graded card and Condition ID 4000 can be used to specify the card as an Ungraded card. If either of these condition IDs are used, the seller is required to use the ConditionDescriptors container to provide one or more applicable Condition Descriptor name-value pairs.

I am try to add ConditionDescriptors for conditionID 2750 and 4000
