No-objection certificate requirement waived where past bill shows ADC remark, enabling expedited import clearance. No-objection Certificate (NOC) from the Assistant Drug Controller (ADC) is mandatory for import of drugs and bulk drugs, but where an importer/CHA produces a past Bill of Entry showing a recorded remark that ADC NOC is not required for the item, the Assessing Group will not require ADC examination or NOC; likewise, in RMS-facilitated Bills of Entry the Docks officer shall not insist on ADC/NOC if such past Bill of Entry is presented, notwithstanding CCR instructions.
