This substance of packing group I shall not be transported or handed over for carriage in portable tanks in the molten state according to sub-section 4.2.1.19 of the RID/ADR/IMDG Code because the assigned tank instruction in Table A, column 10 of RID/ADR or column 13 of the Dangerous Goods List in Chapter 3.2 of the IMDG Code does not refer to carriage of the substance above its melting point. 

Because no tank code for liquids (L) is given for this substance according to Table A, column 12 of RID/ADR, carriage in RID/ADR tanks is also not possible. 

For this substance, carriage in the molten state is therefore prohibited.
