No RCM is not applicable. Supply of Goods/services received by a Registered Person from Unregistered person covered u/s 9(4) of CGST Act, 2017 and required to be paid on RCM if value exceeds 5000 per invoice or cumulatively per day.
But the above sec 9(4) has been suspended till March 2018 as recommend by GST Council in its 22nd GST Council Meeting.
So the above transaction doesnt attract RCM if it is after 13th of October 2017.
pls let me know if you have any further questions.
