I was surprised to only see this now, as I do remember being assured by two of your pilots that their travels to the Taus would be much smoother if their employers were to purchase such a permit. However, everything now appears to be in order and you have been granted a Tau Trading Licence.
We will of course be able to escort you to Harris and back, since most of your raw materials appear to be Silver headed that way. If you are headed for Kusari (if you were to choose not to take the route through the Sigmas), the route there is unfortunately rather Gallic and hostile for us to assist you.
In other news:
The Independent Miners Guild's Tau Trading Licence expired on May 12th.
Tereyo and Supernyl's Military Materials Licences expired on May 11th and 12th respectively.
