Regulations governing the carriage of chemicals byship are contained in the International Convention
for the Safety of Life at Sea (SOLAS Chapter 7) andthe International Convention for the Prevention ofMarine Pollution from Ships, as modified by theProtocol of 1978 relating thereto (MARPOL 73/78).
The regulations cover chemicals carried in bulk, onchemical tankers, and chemicals carried in packagedform.

Regulations Covering Chemicals Carried in Bulk
Revised MARPOL Annex II
Transport of vegetable oils
Chemicals carried in packaged form
Liability and Compensation for Damage in connection with
the carriage of Hazardous and Noxious substances
Preparedness and response dealing with pollution incidents
involving chemicals
IBC Code DefinitionsIBC Code Definitions
The Code applies to ships regardless of size, including
those of less than 500 gross tonnage, engaged in thecarriage of bulk cargoes of dangerous chemicals ornoxious liquid substances (NLS), other than petroleum
or similar flammable products as follows:
Liquid substances
1.products having significant fire hazards in excess ofthose of petroleum products and similar flammableproducts;
2. products having significant hazards in addition to orother than flammability.
Definitions of NLSDefinitions of NLS
Liquids covered by the Code
are those having a
vapour pressure
not exceeding 0.28 MPa
absolute
at a temperature of 37.8C.
Example of Substances not covered by the Code
Acetylene (C22H22) = 0.65 MPa
Chlorotrifluoromethamne (CClF33) = 0.34 MPa

2. MARPOL Annex II2. MARPOL Annex II
For ease of understanding Annex II can be divided into two
clear sections:
i. Pollution categories
ii. Ship type requirements
In addition:
iii. Operational requirements
(for the actual/physical carriage of chemicals in bulk)
MARPOL ANNEX II: Pollution Categorization
Previously there were 5 pollution categories within Annex II:
- categories A, B, C, D and an Appendix III
-Appendix III listed products to which the IBC Code did not apply
As of 1stJanuary 2007 we have 3+1 pollution category system:
- X, Y, Z and OS
- OS or Other Substances - includes apple juice, clay slurry, coal slurry,dextrose solution, glucose solution, kaoline slurry, molasses and water
-Vegetable oils now upgraded from Appendix III (of the IBC Code) toPollution Category Y
- Oil like substances no longer exist (xylene, toluene, pentanes nowrequire CoF and can no longer be carried on product tankers)

Enforcing Compliance of Annex IIIEnforcing Compliance of Annex III
MARPOL How To Do IT:
In the absence of any requirements for surveys andcertification under this Annex, there are two elements
for the verification of theIMDG Code. These are:
A detailed inspection of the required
documentation;
and
An on board verification that paperwork matches
the marking and stowage on board
Documentation
IMDG Code Chapter 5.4:
Each ship carrying dangerous goods or marinepollutants shall have a special list or manifest settingout, in accordance with regulation 4.5 of chapterVII of SOLAS 1974, as amended, and withregulation 4(3) of Annex III of MARPOL 73/78.

8.1.12 Marine Pollutants
The concept of a severe marine pollutant PP is
deleted; they are just designated as P. The
marine pollutant 'bullet' symbol () is also
deleted, but a shipper will still be required to
declare any consignment as being a marine
pollutant in accordance with the IMDG criteria
definition. There is a new section 2.9.3
describing these, and chapter 2.10 has been re-
written. The new marine pollutant label is a
dead tree and dead fish
Marine Pollutants
Substances which belong to any of the 9 classes of hazard which:
Due to bio-accumulation potential in Sea Food
Or high level of toxicity to Aquatic Life
Shall be carried by sea in accordance with the requirements of
MARPOL 73/78 Annex III

segregation required by secondary hazard (subsidiary risk labels),
provided the substancesdo not react dangerously with each other
and cause any of the following:
Combustion and/or evolution of considerable heat; Evolution of flammable, toxic or asphyxiant gases; The formation of corrosive substances; or The formation of unstable substances
