word "ninth" and replace "ST/SG/AC.10/30/Rev.7" with "ST/SG/AC.10/30/Rev.9".
In the definition for "Group A", replace the text to read
"Group A consists of cargoes which possess a hazard due to moisture that
may result in liquefaction or dynamic separation if shipped at a moisture content in
excess of their transportable moisture limit."
In the definition for "Group C", replace the text to read
"Group C consists of cargoes which are classified as neither group A nor
group B."
In the definition for "Manual of Tests and Criteria", replace the
definition to read "Manual of Tests and Criteria means the seventh revised
edition of the United Nations publication entitled Manual of Tests and Criteria
(ST/SG/AC.10/11/Rev.7 and Amend.1)."
In the definition for "Transportable moisture limit (TML)",
replace the text to read "Transportable moisture limit (TML) of a group A
cargo means the maximum moisture content of the cargo which is considered safe for
carriage in ships not complying with the special provisions of 7.3.2. It is
determined by the test procedures, approved by a competent authority, such as those
specified in paragraph 1 of appendix 2."
Add the following new definitions in alphabetical order:
"Cargoes which may undergo dynamic separation means cargoes which
contain a certain proportion of fine particles and a certain amount of moisture, and
may undergo dynamic separation if shipped at a moisture content in excess of their
transportable moisture limit."
"Dynamic separation means the phenomenon of forming a liquid
slurry (water and fine solids) above the solid material, resulting in a free surface
effect which may significantly affect the ship's stability."

4.3 Certificates of test
In 4.3.2, replace the first sentence to read as follows:
-
"When a group A cargo is carried, the shipper shall provide the ship's master
or his representative with a signed certificate of the TML, and a signed
certificate or declaration of the moisture content, each issued by an entity
recognized by the competent authority of the port of loading."
In 4.3.3, replace the first sentence to read as follows:
-
"When a group A cargo is carried, procedures for sampling, testing and
controlling moisture content to ensure the moisture content is less than the
TML when it is on board the ship shall be established by the shipper, taking
account of the provisions of this Code."
In 4.3.5, replace the first sentence to read as follows:
4.4 Sampling procedures
In 4.4.3, replace the existing text with the following:
4.8 Documentation required on board the ship carrying dangerous goods
In 4.8.3, after the words "SOLAS regulation II-2/19.4", add the words "(or
II-2/54.3)footnote", and add a corresponding footnote, as follows:
Section 7 - Cargoes which may liquefy
In the heading for "Section 7", replace the words "Cargoes which may liquefy" with
the words "Cargoes which may liquefy or undergo dynamic separation".
7.1 Introduction
In 7.1.1, replace the existing text with the following:
-
"The purpose of this section is to bring to the attention of masters and
others with responsibilities for the loading and carriage of bulk cargoes,
the risks associated with liquefaction or dynamic separation and the
precautions to minimize the risk. Such cargoes may appear to be in a
relatively dry granular state when loaded, and yet may contain sufficient
moisture to become fluid or unstable under the stimulus of compaction and
the vibration which occurs during a voyage."
In 7.1.3, replace the existing text with the following:
7.3 Provisions for cargoes that may liquefy
In the heading for 7.3, replace the words "Provisions for cargoes that may liquefy"
with the words "Provisions for cargoes which may liquefy or undergo dynamic
separation".
7.3.1 General
In 7.3.1.1, replace the existing text with the following:
-
"Group A cargoes shall only be accepted for loading when the actual moisture
content of the cargo is less than its TML. Notwithstanding this provision,
cargoes having moisture content in excess of the TML may be carried on a
specially constructed or fitted cargo ship for confining cargo shift
specified in 7.3.2."
In 7.3.1.2, replace the existing text with the following:
-
"Notwithstanding the provisions in 1.4 of this Code, the requirements in
4.2.2.9, 4.2.2.10, 4.3.2 to 4.3.5, 4.5, 4.6 and 8 of this Code need not
apply to a group A cargo provided that the cargo is carried on a specially
constructed or fitted cargo ship for confining cargo shift specified in
7.3.2 or on a specially constructed ship for dry powdery cargoes specified
in 7.3.3."
Section 8 - Test procedures for cargoes which may liquefy
In the heading for "Section 8", replace the words "Test procedures for cargoes which
may liquefy" with the words "Test procedures for group A cargoes".

9.2.3.3 Self-heating solids: MHB (SH)
In 9.2.3.3.2, replace the word "33.3.1.6" with the word "33.4.6".

9.2.3.5 Solids that evolve toxic gas when wet: MHB (WT)
In 9.2.3.5.2, replace the word "33.4.1" with the word "33.5".
9.2.3.7 Corrosive solids: MHB (CR)
In 9.2.3.7.3, replace the existing text with the following:
-
"A material shall be classified as MHB when the corrosion rate on a steel
surface is between 4 mm and 6.25 mm a year at a test temperature of 55°C.
For the purposes of testing steel, type S235JR+CR (1.0037 resp. St 37-2),
S275J2G3+CR (1.0144 resp. St 44-3), ISO 3574:1999, Unified Numbering Systems
(UNS) G10200 or SAE 1020 shall be used. An acceptable test is prescribed in
the United Nations Manual of Tests and Criteria, part III, section 37. A
representative sample of the cargo shall be tested at typical as-shipped
cargo conditions, including moisture content by mass, bulk density, particle
size distribution and atmospheric conditions. The assessment of localized
corrosion occurring upon the steel surface shall be performed using national
or international standards. The test shall be conducted taking into account
the guidance developed by the Organization.footnote",
