The Drawback shall be available only of Customs duties on imported inputs and Central Excise duty on items specified in the Fourth Schedule to the Central Excise Act 1944 (specified petroleum products, tobacco etc.) used as inputs or fuel for captive power generation.
As an export facilitation measure, for the transition period of 3 months, from July to September, 2017, Drawback at higher composite rates will continue to be granted subject to certain safeguards i.e. for claiming the higher rate of drawback, the exporter has to make a declaration and certificate is required that no Input Tax Credit (ITC) of CGST/IGST is claimed, no refund of IGST paid on export goods is claimed and no CENVAT credit is carried forward.
In absence of such certification, drawback will be restricted to the customs portion of drawback.

This shall be applicable even for exports made prior to 1st July 2017 for which application is yet to be filed. In case exports are from multiple places, application shall be filed with the Commissioner of Customs having jurisdiction over any one of the places of export of goods.
