I suspect this is described as a Handling Charge, which is permitted. EBay doesn't question what makes up the Handling Charge.
Try multiplying the price of the item by 0.129. That might give you an inkling if the surcharge is actually eBay fees or if it is a Handling Charge which might cover insurance, cost of packaging materials, or labour.
