My two Hazmat books, one from the late 70s and one from the late 80s, don't even HAVE a UN #3431, or "Nitrobenzotrifluorides", solid or other wise. The 70s version doesn;t have UN numbers. Fortunately I model 1974, so apparently this stuff wasn't around then. Here's a page with a little more on the stuff.

The 1970s book is "Emergency Handling of Hazardous Materials in Surface Transportation", September 1977, from the Bureau of Explosives and AAR, and is specially designed for railroads. It has some very interesting stuff, like the fact that lead-acid batteries cannot be shipped in open hopper cars. Why one would want to I have no idea... Hair is considered a spontaneous combustion hazard. I assume that's bailed hair, not hair on ones head, but it doesn't say so. Or maybe "Lithium Borohydride, Flammable Solid, Water Reactive", which calls for using, among other things, graphite as an extinguishing agent. As graphite itself burns, that seems a little strange. Even cosmetics are listed, under various hazard categories.
And then there's this one:
ACID FISH SCRAP (FISH SCRAP CONTAINING LESS THAN 6% OR MORE THAN 12% MOISTURE)
FLAMMABLE SOLIDAcid fish scrap that is too dry is liable to spontaneous heating and ignition, or too wet is liable to decay, spontaneous heating and ignition.
If material is on fire or involved in fireFlood with water.
If material not on fire and not involved in fireKeep sparks, flames, and other sources of ignition away
There are all kinds of interesting names and rules for those who want to complicate their operations.
