This Class 9 placard carries the identification number 3257, which Safehouse Signs lists as its hot asphalt placard. In the 49 CFR 172.101 Hazardous Materials Table, UN3257 is "Elevated temperature liquid, n.o.s., at or above 100 C and below its flash point (including molten metals, molten salts, etc.)", hazard class 9.
Check the temperature first: the same table lists asphalt at or above its flash point under a different entry, "Asphalt, at or above its flash point", NA1999, hazard class 3. This UN 3257 Class 9 placard matches the elevated temperature liquid entry only, not an asphalt shipment at or above its flash point.
