If the building is sprinkled you can have up to 26,400 gallons in the building for Class IIIB. That's spelled out in the IBC, see Table 307.7(1).
Tank construction material is not restricted also as long as the building is sprinkled. NFPA 30, 4.2.2. Although in some cases you may be asked to increase the density and remote area if the tank is plastic or any similar combustible composition. Check with your AHJ and/or Underwriter. You also need to know what else is being stored near that tank. If there are Class I or II flammables then there are relief venting requirements. Also you might walk through the decision tree in NFPA 30, Chapter 6.8 and see where your IIIB fits. That tree can help when there is some question how to protect the area and it's not printed in black and white. And by all means, get an MSDS on the stuff. Craig L.
