The revenue generated from customs duty has an increasing trend from 2009-10 to 2016-17. As the customs (CVD & SAD) has been subsumed under GST from 1^st July 2017, the customs duty collection has declined in 2017-18 and 2018-19 while the revenue generated from IGST+ Compensation Cess (Net) from imports has substantially increased in past two years.

This information was given by the Union Minister of Commerce and Industry, Piyush Goyal, in a written reply in the Lok Sabha today.

Subsumption of CVD and SAD under GST reduced customs duty receipts and shifted import revenue to IGST and cess. The subsumption of CVD and SAD into GST from 1 July 2017 shifted import-related revenue composition: customs duty receipts, which rose from 2009-10 to 2016-17, declined after subsumption, while IGST plus Compensation Cess net receipts from imports increased substantially, indicating a reallocation of import tax revenue streams rather than growth in total import taxation.
