2.1 The facts briefly stated are that M/s. SSN Trading Co., Madurai (hereinafter referred to as ‘the Appellant’) imported Cement of Pakistani origin through Tuticorin Port under 3 Bills of Entry classified under CTH 2523 2910 during various periods. The Appellant availed concessional CVD in terms of Notification No. 04/2006-CE dated 01.03.2006, as amended—two Bills of Entry under Clause 1(C) (for cement other than that cleared in packaged form) and one Bill of Entry under Clause 1A(ii) (for cement in packaged form with RSP exceeding ₹190). SIIB, Tuticorin initiated post-clearance investigation alleging that the cement was imported in packaged 50-kg bags and that the Appellant had mis-declared the Retail Sale Price (RSP) as ₹190/- per bag at the time of import, thereby wrongly availing the benefit of Clause 1(C) and short-paying CVD. Based on this allegation, a differential duty of ₹16,278 /- was demanded under Section 28(4) of the Customs Act, 1962 for alleged suppression and mis-declaration, along with interest under Section 28AA and equal penalty under Section 114A.
