    1. Dear Deepak, UN 2990 is LIFE-SAVING APPLIANCES, SELF-INFLATING, there are nothing special other than following the normal process of IMDG Code. Most shipping lines do accept this.

  1. Kindly advise which HAZ stickers are to be put in the container for Class 9/UN No.3082/PG III/ ENVIRONMENTALLY HAZARDOUS SUBSTANCE, LIQUID, N.O.S. &
    Class 8/UN No.1910/CALCIUM OXIDE

    1. Hello Narayanan,

      On container it is Placards.
      For UN 3082, Class 9 Placards must be affixed on all four sides of the contianer, if the product is marine pollutant then MP maring ( Dead Fish and Dead Tree) also must be affixed on all four sides of the container.
      For UN 2910 , For Ocean Transport CALCIUM OXIDE is not hazardous cargo

      Regards/Shashi

  2. UN3166 Class 9 EMS : F-E, S-E

    Haz declaration by Packer however both motorcycles drained of fuel and oil plus battery removed.

    Surely NON-HAZ ?

  3. Hello,

    We manufacture 1950 class 2.1 and 2.2 products that require heat protection for shipping during winter months. We ship limited quantity against POs that also call for non-DG items needed heat protect in winter. Please advise on best method of shipping on ocean freight if use of reefer container not allowed.

    Thank you.

    1. Hello Rahul,

      You need to check column 16b of dangerous goods and apply the provisions if applicable
      Example
      UN 1814 Class 8 (Column 16b = SG35 – Separated from Acids)
      UN 1830 Class 8 (Column 16b = no segregation requirement) this substance is an acid listed in section 3.1.4.4 of IMDG Code
      Hence both cannot be loaded together.

      You may refer to below links for more understanding

  5. Hi There,

    One of our customers requires the DGN’s to be produced electronically through their DLX warehouse system. Which signatures on the DGN can be automated (name printed in capitals) and which cannot?

    Thanks

    1. Hello Martin,

      Apologies for delay in replying as I was traveling.
      According to 5.4.1.6.2 of IMDG Code If the dangerous goods documentation is presented to the carrier by means of EDP or EDI transmission
      techniques, the signature(s) may be electronic signature(s) or may be replaced by the name(s) (in capitals) of
      the person authorized to sign.

  7. Why is Cobalt (II) oxide considered a marine pollutant and classified as Environmentally Hazardous Substance?

    1. Hello Lisa,

      I am not sure under which UN Number this is classified with which concentration of Cobalt (II) Oxide. Pure cobalt (II) oxide is classified under toxic solids and meets the criteria of GHS for environmentally hazardous substance ( marine pollutant )

      Regards/Shashi

  8. Hi Shashi,
    It’s Antoine again from France.
    I have a doubt about technical names on tanks when having a SP 274:
    Do we need or not putting them? If we read 274, it says “for purpose of package”. Do that includes tanks or not?
    Thanks very much

    1. Hello Antoine,
      Tank does not include in definition of ‘package’ in SP 274. If you refer section 5.3.2.0.1.1 of IMDG Code it says Proper Shipping Name of the contents shall be durably marked on at least both sides of the Tank. This marking must be displayed in characters not less than 65 mm high. However you may additionally display technical name within brackets next to Proper Shipping Name.

      Regards/Shashi

  9. We are shipping UN1133 Adhesives/Packaging Group III/Transportation Hazard Class3 by ocean. This UN is subject to Shipping Hazmat Limited Quantities (5L.) Do I have to declare this shipment as hazard? what documents need to be provided and what carton marks or labels are required for this shipment. Product is pack of containers from 1.5 oz – 4 oz. each.

    1. Hello Giuliana,
      Yes, this must be declared in dangerous goods declaration.
      Declaration should read as below
      UN 1133 ADHESIVES containing flammable liquid Class 3 PG III (flashpoint in Celsius closed cup) limited quantity.
      Number and kind of packages, total gross mass. (example 100 fibreboard boxes 250 kg)

        Carton must be marked as below

      for label specimen refer https://www.shashikallada.com/limited-quantity-marking/

      The top and bottom portions and the surrounding line shall be black. The centre area shall be white or a suitable contrasting background. The minimum dimensions shall be 100 mm (100 mm and the minimum width of line forming the diamond shall be 2 mm. If the size of the package so requires, the dimension may be reduced, to be not less than 50 mm) 50 mm provided the marking remains clearly visible.
      The total gross mass of the package shall not exceed 30 kg.

      Container, carrying only dangerous goods in limited quantities, shall be placarded with same format; the minimum dimensions shall be of 250 mm x 250 mm on all four sides.

      Regards/Shashi

  10. If I have a dangerous substance where the secondary hazard is class 3 and this has a flash point lower than 60 degrees C, does this require entering on the DGD for IMDG?

    1. Hello Mick,
      Yes, flashpoint, in closed cup, has to be written after the basic description of dangerous goods.
      Example UN 2920 CORROSIVE LIQUID, FLAMMABLE, N.O.S.(technical name) Class 8 (class 3) PG II (43 Deg C.c.c.)

      Regards/Shashi

      1. Thank you.
        That is what I thought but it is not very clear in the books. It only refers to when Class 3 is the primary hazard.

        Thank you again

        Mick

        1. Mick,
          Declaration of flashpoint is part of Information which supplements the Proper Shipping Name in the dangerous goods description and is mentioned in section 5.4.1.4.3.6 of IMDG Code, which states, “Flashpoint: If the dangerous goods to be transported have a flashpoint of 60°C or below (in °C closedcup (c.c.)), the minimum flashpoint shall be indicated.”

          Regards/Shashi

  11. Bulk – UN 3082

    call or text

    1. Hello Fred,
      You need to look at the country specific rule for making of road vehicle carrying goods of Class 9.
      Which country are these class 9 being transported by road?

      Regards/Shashi

  12. Good Day, Please could you inform me about the relevant legislation that deals with opening of explosives containers after it has been loaded onto a vehicle propelled by mechanical power and who,or which relevant authorities must be present when the container needs to be opened.
    Thank you

    1. Hi Mervin,
      I am not aware which country’s regulations you are asking about.
      Each country, with respect to their local rules, may have desingnated department responsible for granting permission as well to overseeing the operations of loading/discharging explosives from road vehicles or ships.

      Regards/Shashi

      1. Thank you for the response. I have a copy of IMDG Code Volume 2, 2014 Edition and was looking to find any regulations within the Code that stipulates the off-loading process, if you are able to provide any specifics relating to that matter. I am currently looking through our local regulations as per the designated departments. I am based at Durban, South South Africa.
        Thank You

    1. Hi Maria
      ISOPHORONEDIAMINE – Class 8 UN 2289 does not belong to any segregation group.

      Xylylenediamine is generally assigned to N.O.S. entries and depending on the concentration n.o.s. entry used will be alkali. I am not sure which UN Number your product containing Xylylenediamine is

      Regards/Shashi

      1. Thanks Shashi,

        details are
        UN 1760 CORROSIVE LIQUID, N.O.S. (ISOPHORONEDIAMINE , XYLYLENEDIAMINE)
        CLASS 8 PG: III EMS: F-A,S-B

        hope this will assist in getting the segregation group.

        1. Maria,
          UN 1760 is not assigned to any segregation group.
          However, if the chemical being shipped, in this case ISOPHORONEDIAMINE, XYLYLENEDIAMINE, is strong enough then shipper should assign segregation group “Alkali”.

          Regards/Shashi

          1. Good Morning sahsi,

            can you advise what how to check inner/ outer packing for batteries UN3091 as per shipper it is packed in fiberboard boxes

  13. Good Evening!!! I wanted to know the IMDG code used for Perfumes Cargo??? I mean what number of code we will use for Perfume Shipment.

    1. Hello Farrukh,

      Perfumery products which are flammable liquid is listed under entry in IMDG Code as mentioned below.

      UN Number : 1266
      Proper Shipping Name : PERFUMERY PRODUCTS with flammable liquid
      Packing Group II or III depending on the flashpoint

      There are other provisions applicable to above depending on the product’s properties.

    1. Hello Rizik,
      Same label with differing flame in black and white are contrast options for the color of package. A white flame label will be more visible on a dark colored package. Similarly a dark flame label will be more visible on a light color package.

      Regards/Shashi

  14. In D.G. stowage what is the meaning, better, what is referred to closed versus open, closed versus closed etc.

  15. Good Morning Shashi,
    I am a newcomer reading your interesting blog, I am a former Master and now I train cadets in Italy, they asked me a introduction course to D.G. of which, I have lost some knowledge, therefore I re-phrase my earlier question: when you stow a CTU of D.G. goods not compatible with others, what means CLOSED VERSUS CLOSED, CLOSED VERSUS OPEN ETC.
    The English language is easy to understand but sometime difficult for interpretation, is it referrred to bulkheads, CTU doors….., I know that is related to segregation one, two, three off separated by bulkheads or decks, but the above mentioned terms drives me nuts, can you kindly explain?
    Many thanks Maurizio M.

    1. Good Morning Maurizio,

      Refer to table 7.4.3.2. In IMDG CODE, this table lays down segregation between containers vertically and horizontally (athwartships and fore ans aft).

      Consider two CTUs both closed containers having segregation rule “separated from”. Now consider one of the CTU is open container ( open top or flat rack) you an see the difference in segregation in above mentioned table.

      Open and closed refer to closed containers and open top or flat racks which are not closed containers.

      Sorry am replying to you through my mobile phone hence unable to type in more details. You may further refer to MSC Circular 1440 in below link for illustration of segregation of containers
      https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/300845/msc.1-circ.1440.pdf

      Regards Shashi

      1. Many thanks Shashi, I have gone through circ.1440 various times but it is really difficult to interpret the meaning, the circular doesn’t explain the difference between the type of containers, it is quite confusing at least for those not owning the language as you do, I have struggled to look at the drawings of the circular but always looking at the position of the doors or the bulkheads, I have transported CTU with D.G. but always closed containers I have never seen an open one with D.G. Sorry for the late reply due to Xmas Holidays, best wishes and kind regards Maurizio

        1. Hello Maurizio,

          Season’s greetings!

          When am back at my laptop next week, i will send you some photos of open container with dangerous goods. Which may give you some fair idea about open vs closed and open vs open segregation as illustrated in MSC circular.

          May be I can assist you with some PPT for explaining each of these terms graphically too.

          Regards/Shashi

  17. for shipment of UN 2291 – IMO 6.1 – bulk in 20′ containers: are there restrictions for shipment by container?
    Special instructions except for the labeling?
    If a plastic liner is used to easily clean container after discharge, should this plastic liner meet specific requirements?

    1. Good Day Gerd,

      If you are asking about IMDG Code for carriage of UN 2291 then Bulk containers are not allowed as there is no BK code assigned in column 13 of Dangerous Goods List.

      Regards/Shashi

    1. Good Day Yash,

      IMDG Code is applicable to all ships to which the SOLAS, 1974, as amended, applies and which are carrying dangerous goods as defined in regulation 1 of part A of chapter VII SOLAS.
      Further, all ships carrying substances, materials or articles identified in IMDG Code as marine pollutants are subject to the provisions of IMDG Code.

      Coal is listed in IMSBC Code, not in IMDG Code

      Regards/Shashi

  18. Hello,
    I have a question regarding IMDG and vehicles.
    I read down 961 and 962 provision for UN3166. I plan to ship vehicle on flat container (not RO-RO).
    However, I would like to ask, if I need to specify on Multimodal Dangerous Goods Form quantity of fuel (UN1202), wet battery (UN2794), engine oil (UN3082), and if I need to attach MSDS for UN1202, UN2794, UN3082?
    Or UN3166 is enough on Multimodal Dangerous Goods Form.
    Thank you so much for your assistance.
    Stefan

    1. Hello Stefan,

      We must not mention individual hazardous substances and articles of vehicles such as fuel (UN1202), wet battery (UN2794), engine oil (UN3082). Mentioning such is violation of regulation.
      We must mention only UN 3166, however, we must choose the correct proper shipping name for UN 3166 that is VEHICLE, FLAMMABLE LIQUID POWERED (believe your vehicle is not having fuel cells or fuel gas).

      Vehicles transported Under UN 3166 of IMDG Code 37th amendment must meet the requirements of special provision 962 which limits the quantity of fuel and other parameters. Please refer to my article about same in link https://www.shashikallada.com/planes-trains-and-automobiles-imdg-code-37-14/

      Regards/Shashi

  19. Hallo Shashi,
    For UN 3065 PGIII, special provision 145 states :” Alcoholic beverages of packing group III, when transported in receptacles of 250 L or less, are not subject to the provisions of this Code.” Does this mean boxes with inner receptacles as per Packing instruction 001 and drums containing this product do not have to be labeled or placarded?

    1. Hello Jannie,
      You are correct, combination packagings with inner receptacles or single drums carrying UN 3065 PG III need not me marked or labelled or documented, container need not be placarded, provided each receptacle contains less than 250 litres of UN 3065 PG III .

      Regards/Shashi

  20. we are handling UN 8 class material in IBC and Tankers.
    could you please advise on labelling and tranportation regulations in India.
    who many types of labels has to be fixed on IBC and Tanker and how many labels to be fixed on each IBC and Tanker

    1. Good Morning Shrikant,

      Dangerous Goods by road in India must meet the labeling and other requirements of

      Central Motor Vehicles Rules (1989),

      You may refer to parts 129 to 137 of said rules for labeling, emergency information panel, tremcard, instructions to driver etc.

      Regards/Shashi

    1. Martin,

      I looked into the supplement to 36th amendment and did not find UN 2661 Hexachloroacetone included in the list of substances where Chemicals allocated to specific treatment is available. UN 2661 does not have any specific treatment, when needed treatment to be done as per the exposure and symptoms.

      Regards/Shashi
