GST Applicability between an Indian assesse and a Foreign company

Current Scenario:  "X" is an Indian company dealing in the business of providing goods to "Y" a Foreign-based company, through its agents in India. X while sending the invoice to Y charges IGST. Now, "Y" resells those goods received from "X" to a Company "Z" setup outside India. 

Question: Is there any way for Y to use/take credit of the IGST charged on the purchase invoices?
