"Afghanistan" (the recently routed government) is not on the list. The Taliban is not a (yet) recognized nation-state in most Western countries. It'll take time for these lists to get updated with recent events.

Considering that the Taliban is/was a hostile party to an active US military operation, starting economic activities with them without explicit government approval is probably not a good idea.

The Taliban (in Afghanistan; the Pakistani Taliban is on both the Treasury and State lists), as well as a very large number of persons and organizations associated with the Taliban separately, is on the Treasury Department OFAC Sanctions list even though for diplomatic reasons the Taliban has not been included on the State Department list of international terrorist organizations.
