CBIC has clarified that All Industry Rate (AIR) of duty drawback should not be denied or reduced for export goods manufactured using inputs, some of which are non-duty paid or subject to concessional duty.
Reference: Board Circular No. 19/2005-Customs dated March 21, 2005, which states that AIR duty drawback rates are determined based on the average duties paid on inputs. The calculation considers a weighted average of imported and indigenous inputs used by exporters, and field officers should not investigate whether exempted inputs were used.
Directive: Field formations must strictly adhere to the clarification in Circular No. 19/2005-Customs, and suitable standing orders should be issued to ensure compliance.
