Dangerous goods advice- UK regs and ADR

Hi Dave

A question on marking a multi pot Tank Container. Pot 1 contains a Class 3, UN1262 and so does pot 2. The rear pot holds Class 3, UN1300. On the front and both sides of pots 1&2 is a flammable placard also the on the sides is the product name. Pot 3 has flammable placards on both sides and the rear plus product name on both sides. The question is should a placard showing UN1300 also be on the front? The Tank Container is marked up for IMDG.
