According to new findings [here: Appendix VI of Regulation (EC) 1272/2008 (CLP Regulation)], the substance has additional toxic properties (Acute Tox. 3). 2.0.0.2 of the IMDG Code states that a substance named in the Dangerous Goods List in Chapter 3.2 that meets the classification criteria for a hazard class or division that is not identified in the list may be consign with the approval of the competent authority as follows:

- under the most appropriate "generic" or "not otherwise specified" (N.O.S.) entry reflecting all hazards; or

- under the same UN number and name but with additional hazard communication information as appropriate to reflect the additional subsidiary hazard(s) [...] provided that the primary hazard class remains unchanged and that any other transport conditions [...] that would normally apply to substances possessing such a combination of hazards are the same as those applicable to the substance listed.

However, the above options are not obligatory but rather can be chosen alternatively. However, because the additional hazard of Class 6.1 would change the carriage conditions (higher requirements of UN No. 1992 packing group I), only the first variant would be available here.

The consignor may also consign the substance under the UN No. and name of the substance named without indicating the additional hazard(s).
