For the purposes of this Annex, substances identified by any one of the following criteria are harmful substances:

Section 2.9.3 of IMDG Code 35-10 sets out the classification criteria for Environmentally hazardous substances (aquatic environment)

Chapter 2.10 defines Marine pollutants as “substances which are subject to the provisions of Annex III of MARPOL 73/78, as amended”

Index of IMDG Code 35-10 and Column 4 in Dangerous Goods Lists in chapter 3.2 identifies Marine Pollutants with symbol P.

However when a substance, material or article possess the properties of  marine pollutant but not identified in IMDG Code as such it shall be transported according to the relevant provisions for carriage of marine pollutants.

Packages containing marine pollutants must be marked with the recognized chemical name of the marine pollutant and bear the Marine Pollutant mark set out in section 5.2.1.6.3 of IMDG Code 35-10 which is shown below

dimensions shall be at least 100 mm × 100 mm, except in the case of packages of such dimensions that they can only bear smaller marks.

However single packagings and combination packagings  having :
– a net quantity of 5 l or less for liquids; or
– a net mass of 5 kg or less for solids

need not be marked.

Containers containing marine pollutants must be marked with marine pollutant mark having minimum dimensions of 250 mm x 250 mm one on each side and one on each end of the container even if the container contains packages not required to bear the marine pollutant mark
