(1) An importer entering any imported goods under section 46, or an exporter entering any export goods under section 50, shall, save as otherwise provided in section 85, self-assess the duty, if any, leviable on such goods.

(2) The proper officer may verify the the entries made under section 46 or section 50 and the self assessment of goods referred to in sub-section (1) and for this purpose, examine or test any imported goods or export goods or such part thereof as may be necessary.

Provided that the selection of cases for verification shall primarily be on the basis of risk evaluation through appropriate selection criteria.

(3) For the purposes of verification under sub-section (2), the proper officer may require the importer, exporter or any other person to produce any document or information, whereby the duty leviable on the imported goods or export goods, as the case may be, can be ascertained and thereupon, the importer, exporter or such other person shall produce such document or furnish such information.

(4) Where it is found on verification, examination or testing of the goods or otherwise that the self- assessment is not done correctly, the proper officer may, without prejudice to any other action which may be taken under this Act, re-assess the duty leviable on such goods.

(5) Where any re-assessment done under sub-section (4) is contrary to the self-assessment done by the importer or exporter and in cases other than those where the importer or exporter, as the case may be, confirms his acceptance of the said re- assessment in writing, the proper officer shall pass a speaking order on the re-assessment, within fifteen days from the date of re-assessment of the bill of entry or the shipping bill, as the case may be.

Explanation.- For the removal of doubts, it is hereby declared that in cases where an importer has entered any imported goods under section 46 or an exporter has entered any export goods under section 50 before the date on which the Finance Bill, 2011 receives the assent of the President, such imported goods or export goods shall continue to be governed by the provisions of section 17 as it stood immediately before the date on which such assent is received.
