I'm assuming you're talking about the USA - UL746C is used for Polymeric Enclosures. Attended Use products - hair dryers, etc. require 94V-2 minimum. Unattended Use products require V0. Permanently Connected to the building structure require 945V. Under all instances, a material with a reduced flame rating is acceptable if the molded part pass a flame equivalency test - 5" flame, Hot Wire Ignition, etc.
Of course, the product's end Standard has the final say on requirements and needs to be reviewed. I'm guessing your product is UL60950 and will have to refer to the experts on that.

When, or rather on what products, does the UL94V0 burn test apply? If the electronic product is battery powered with less than 5V, must it meet this rating? If the battery is Li? Product is portable, contains GPS receiver, and has a 2.4 RF modem. Any 'gotcha' requirements should be aware of? - This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
