- Table 2 to Part 153—Cargoes Not Regulated Under Subchapters D or O of This Chapter When Carried in Bulk on Non-Oceangoing Barges

The cargoes listed in this table are not regulated under subchapter D or O of this title when carried in bulk on non-oceangoing barges. Category X, Y, or Z noxious liquid substance (NLS) cargo, as defined in Annex II of MARPOL 73/78, listed in this table, or any mixture containing one or more of these cargoes, must be carried under this subchapter if carried in bulk on an oceangoing ship.

Explanation of symbols and abbreviations used in this table:

“#” = No determination of noxious liquid substance status. For shipping on an oceangoing vessel, see 46 CFR 153.900(c).

Bolded entries were added from the March 2012 Annex to the 2007 edition of the IBC Code (MEPC 63/23/Add.1), the December 2012 IMO Marine Environmental Protection Committee Circular (MEPC.2/Circ.18), or the December 2013 IMO Marine Environmental Protection Committee Circular (MEPC.2/Circ.19).

“Cat” = Pollution category.

“NF” = Non-flammable (flash point greater than 60 °C (140 °F) closed cup).

“n.o.s.” = Not otherwise specified.

“OS” = Other substances, at present considered to present no harm to marine resources, human health, amenities, or other legitimate uses of the sea when discharged into the sea from tank cleaning or deballasting operations.

“see” = A redirection to the preferred, alternative cargo name-for example, in “Tetrasodium salt of Ethylenediaminetetraaacetic acid solution, see Ethylenediaminetetraacetic acid, tetrasodium salt solution,” the pollution category for “Tetrasodium salt of Ethylenediaminetetraaacetic acid solution” will be found under the preferred, alternative cargo name “Ethylenediaminetetraacetic acid, tetrasodium salt solution.”

“ST” = Ship type, as defined in Chapter 2 of the IBC Code.

“X, Y, Z” = Noxious liquid substance category of Annex II of MARPOL 73/78.
