I wasn't even aware of the Eorzeans trying to get around Hingan tariffs - is it linked to the Eureka or Namazu quests? (I've given up on the former and don't have a DoH / DoL class high enough to do the latter.)

Furthermore if it's the act of Eorzean companies (the East Aldenard Trading Company is the only known Eorzean operation that far east), that's a very different issue than the Eorzean government sponsoring or actively attempting to evade Hingan tariffs.

Red herring either way. Stop digressing, please.
