Did you create a history for the account before you started listing?
The value of the item youre selling is fairly high which Ebay would deem high risk. You should start with lower valued items.

regardless of whether the items being offered were brand named or generic, the value of the items are very high for a new account. Without any selling history on the account prior those items should be considered very high risk.
