Sec. 1400. Misdeclaration, Misclassification, Undervaluation, in Goods Declaration. – Misdeclaration as to quantity, quality, description, weight, or measurement of the goods, or misclassification through insufficient or wrong description of the goods or use of wrong tariff heading resulting to a discrepancy in duty and tax to be paid between what is legally determined upon assessment and what is declared, shall be subject to a surcharge equivalent to two hundred fifty percent (250%) of the duty and tax due. No surcharge shall be imposed when the discrepancy in duty is less than ten percent (10%), or when the declared tariff heading is rejected in a formal customs dispute settlement process involving difficult or highly technical question of tariff classification, or when the tariff classification declaration relied on an official government ruling. There is undervaluation when: 

• (a) the declared value fails to disclose in full the price actually paid or payable or any dutiable adjustment to the price actually paid or payable; or 

• (b) when an incorrect valuation method is used or the valuation rules are not properly observed, resulting in a discrepancy in duty and tax to be paid between what is legally determined as the correct value against the declared value. When the undervaluation is established without the need to go through the formal dispute settlement process provided for in this Act, a surcharge shall be imposed equivalent to two hundred fifty percent (250%) of the duty and tax due. No surcharge shall be imposed when the discrepancy in duly is less than ten percent (10%); or the declared value is rejected as a result of an official ruling or decision under the customs dispute settlement process involving difficult or highly technical question relating to the application of customs valuation rules. A discrepancy in duty and tax to be paid between what is legally determined and what is declared amounting to more than thirty percent (30%) shall constitute a prima facie evidence of fraud. When the misdeclaration, misclassification or undervaluation is intentional or fraudulent, such as when a false or altered document is submitted or when false statements or information are knowingly made, a surcharge shall be imposed equivalent to five hundred percent (500%) of the duty and tax due and that the goods shall be subject to seizure regardless of the amount of the discrepancy without prejudice to the application of fines or penalties provided under Section 1401 of this Act against the importer and other person or persons who willfully participated in the fraudulent act.
