At present, in China, there are more than 20 varieties traded through the futures exchange, including commodities, metals, industrial products and so on, but there is no tea futures you asked.

I think, since you asked about tea futures, I'm sure you didn't do it for no reason. Or the tea futures you mentioned are in the process of spot trading of tea. Because tea has a production process, before tea production and sales, tea farmers, tea factories and tea merchants sign sales contracts in advance, which is also called futures (meaning: forward delivery).

Tieguanyin in Anxi, Fujian is good. I stayed in Fujian for four years. A friend's family is exporting tea abroad (mainly in Southeast Asia).
