Presently under Central law, exporters are allowed to obtain duty paid inputs, avail ITC on it and export goods upon payment of duty (after utilizing the ITC) and thereafter claim refund of the duty paid on exports. Will this system continue in GST?

Under the GST regime exports will be zero rated
which means that the export goods would not suffer
any actual tax liability although inputs for such exports
would be tax paid. Under GST, refund will be allowable on
the accumulated inputs as well as on exported finished
goods.
