Concessional duty removal: commencement fixed and security requirement abolished for availing concessional removal benefits under the Rules. The amendment fixes the commencement of the 2016 Rules as 16th March, 2016 and removes the requirement of providing 'or security' in rule 4(5), eliminating the security obligation for availing concessional removal of goods. It also inserts a new rule directing that any reference to the 2001 Rules in subordinate instruments be read as a reference to the 2016 Rules and corresponding provisions.
