Yes, GST is applicable in India on the commission earned in foreign currency from foreign suppliers.
Why?
-
You are acting as an intermediary (agent) under Section 2(13) of the IGST Act.
-
As per Section 13(8)(b) of the IGST Act, the place of supply for intermediary services is the location of the supplier (i.e., India).
-
Hence, it does not qualify as export of service, even if payment is in foreign currency.
-
GST must be paid on the commission.
No relief available under export provisions due to place of supply being India.
