After we present cost , they a bit worry and concern since seem SOC ISO Tank + Ocean freight which we provide are higher than the Felxibag option that some provider offer them , understand they need to get the best cost for this transport mode but anyhow they still not say they no need to used ISO TANK anymore since many operation concern and still working on license and export Quota first that is the key right now.
Anyway I will keep an eye and updated you if any concluded from customer site,
