Rule 12 permits rejection of declared customs value only where there is reason to doubt its truth or accuracy, the importer has an opportunity to explain the price, and valuation follows the prescribed method, including contemporaneous import values where relevant. Unsupported intelligence and recovered documents did not establish undervaluation, rendering redetermination and differential duty unsustainable. Electronic data, messages, emails and invoices required statutory certification and reliable authentication; unauthenticated material could not prove undervaluation. Each IEC holder filing its own bill of entry remained the importer liable for duty, preventing recovery from an alleged proxy importer. Goods unavailable for confiscation could not attract confiscation or redemption fine.
