Permanent markers are used for writing or marking on metals, plastics, ceramics, wood, stone, cardboard etc. The ink comprises a main carrier solvent, a glyceride, a pyrrolidone, a resin and a colorant. Like spray paint, these markers contain volatile organic compounds which evaporate to dry the ink. Permanent marker is another name for “waterproof” marker. They have a potential for abuse as a recreational drug. [Wikipedia]

  1. Hi Shashi,
    Why these markers pen should not be not classified under UN 3363 ?
    Best regards

    1. Hello Antoine,

      I do not think PEN can be put under the term APPARATUS. I may be wrong.
      When we look at lighters containing flammable liquid in IMDG Code there is no clarity to place this under special provision 301 of UN 3363 but 49 CFR has an entry specific for domestic transport as Lighters, non-pressurized, containing flammable liquid Class 3 NA1057 PG II

      PS : I have seen an Helicopter under UN 3363 with an approval of competent authority.

      1. Shashi,
        On the possibility that permanent markers are now classified as dangerous goods, I have been researching for an SDS this morning to no avail for “A typical permanent marker is assigned to UN 1993 FLAMMABLE LIQUID N.O.S”. Please advise with current SDS as we ship these types of markers every week and this is the first time that I have heard of this.
        Thank you so much for keeping us current on IMDG Codes. I truly appreciate it.

        1. Hello Annette,

          It all depends on the property of the ink. If the ink is flammable with flashpoint equal to or less than 60 Deg C then the product need to be classified as dangerous.
