IMDG Code chapter 5.4, Documentation, states Proper Shipping Names that are assigned special provision 274 in Column 6 of the Dangerous Goods List shall be supplemented with their technical or chemical group names as described in 220.127.116.11.
Section 18.104.22.168 states ““Generic and “not otherwise specified” Proper Shipping Names that are assigned to special provision 274 or 318 in column 6 of the Dangerous Goods List shall be supplemented with the technical or chemical group names unless a national law or international convention prohibits its disclosure if it is a controlled substance.”
So we understand that when special provision 274 or 318 is assigned to any entry in Dangerous Goods List same must be provided with a technical name!
This is not the end of the requirement ;-) there is one more special provision which asks for technical names. This is SP 220 assigned to UN 3248 MEDICINE, LIQUID, FLAMMABLE, TOXIC, N.O.S
Note that UN 1851 MEDICINE, LIQUID, TOXIC, N.O.S. is not assigned with SP 220 only UN 3248 MEDICINE, LIQUID, FLAMMABLE, TOXIC, N.O.S is assigned with SP 220
SP 220 states that the technical name of flammable liquid component shall be shown in brackets immediately following the Proper Shipping Name.
