GST on services discharged outside state by agent.

We are registered in MP and a person registered in UP locates raw materials for us in distilleries across India and charges us Rs 1/L for this. On our behalf, if he goes to a distillery in PUNJAB, assesses quality and quantity of raw material and takes delivery of the material on factory gate,

1. Will this person be considered as an Agent as mentioned in GST and if sos, will his offices in UP be considered as our offices as well? If yes, will we have to get registered in UP as well?

2. Since the service that he will discharge take place in another state (Punjab) will he have to take registration in Punjab as well?
