The rules on Customs valuation according to the BDV are based on the notional concept of “value” which treats the dutiable value as the “normal price” at which the goods would be sold in an open market between an importer and an exporter operating independently. The “normal price” is the open market price at which the goods are freely available to any buyer subject to compliance with certain conditions. For example, if a sole agent receives a special discount, which is not granted to other importers, it has to be added to the price to arrive at the normal or open market price for Customs valuation purposes.
