Declared customs transaction value may be rejected only on cogent evidence of extra consideration or reliable contemporaneous imports of comparable goods at higher prices. The notes state that unsupported statements, uncertified electronic records, and uniform loading without consignment-specific comparability do not establish undervaluation. Where final assessments were made and no fraud, collusion, wilful misstatement, or suppression with intent to evade duty is proved, the extended demand period is unavailable. If the valuation-based demand fails, consequential duty, confiscation, interest, and penalty cannot stand; seized currency lacking a proven nexus must be released, and investigation deposits must be refunded with applicable interest.
