Dear Experts🙏..
My Client GST registration is in Tamil Nadu. He buys goods in China and sells the same goods to South Africa.
Goods never arrive in India. Goods go directly from China to South Africa.

He gives money through Dollar and receives money through Dollar.

Whether to report turnover in 3B and GSTR-1.
Which document should we have in hand for this?
