Implementation of the CLP Regulation
Classification for Portland cement clinker and common cements
31 January 2011
Introduction
The new Regulation on classification, labelling and packaging of substances and mixtures
(CLP, Regulation 1272/2008) requires substances and mixtures to be classified for a number
of hazardous properties, the so-called hazard classes or endpoints. There are three categories
of hazard classes: physical hazards, health hazards and environmental hazards.
In order to correctly classify a substance or mixture, the manufacturer or importer has to take
into account all available information (amongst others new data generated from tests in
accordance with the CLP; epidemiological data and human experience data, such as
occupational data and data from accident databases; or information generated under REACH).
There is no obligation to carry out new tests for the health hazards or environmental hazards
for endpoints for which information is missing. However, for physical hazards, the tests have to
be carried out if no information is available.
Classifying substances in accordance with the new classification under the CLP Regulation is
mandatory as of 1 December 2010. Mixtures need to be classified according to the CLP as of
1 June 2015, but they can be classified according to the CLP prior to this date. The
CEMBUREAU Board decided that the new classification for common cements under the CLP
Regulation should be used as of 1 December 2012.
The first two sections of this document contain the classification and labelling for Portland
cement clinker and common cements as agreed by the CEMBUREAU Board on 28 September
2010. The last section contains a table with for each endpoint/hazard class, the source of the
information and an argumentation used to derive the classification.
A “-” in a cell” means that an assessment was made and the data is sufficient to conclude that
no classification is necessary for the specific endpoint.
The full set of studies used for the classification (and also referred to in the templates for the
SDS for Portland cement clinker and common cements (T16579 and T16580) are available on
CEMBUREAU’s extranet. The pictograms used for the pictogram which shows the Personal
Protective Equipment recommended to work with cement are also available from the extranet.

but the same details need to appear in all languages used and the statements have to be
grouped per language. For packaging between 3 and 50 litres, the label is to be at least

surface and be at least 1 cm² wide (CLP Annex I 1.2)
If the cement is provided in bulk (unpackaged), the labelling information and other relevant
hazard information is provided through other means than a label, usually through the Safety
Data Sheet. However, if the bulk cement is provided to the general public, a copy of the label
elements is to be added.
The following pictogram should be added on the bags of cement (but not included in the label
itself).
Supplemental information (1)
Unless cements or cement mixtures are already classified and labelled as a sensitiser with the
hazard statement H317, ‘May cause an allergic skin reaction’, the label on the packaging of
cements and cement mixtures that contain, when they are hydrated, more than 0,0002 %
soluble chromium (VI) of the total dry weight of the cement shall bear the statement:
EUH203 — ‘Contains chromium (VI). May produce an allergic reaction’
If reducing agents are used, then the packaging of cement or cement-containing mixtures shall
include information on the packing date, the storage conditions and the storage period
appropriate to maintaining the activity of the reducing agent and to keeping the content of
soluble chromium VI below 0,0002 %.

Clinker is not explosive or pyrotechnic as it is
not in itself capable by chemical reaction of
producing gas at such temperature and

damage to the surroundings. It is not capable of
a self-sustaining exothermic chemical reaction.

unstable or is not liable to undergo a strong
exothermic decomposition even when devoid
participation of oxygen (air).
Clinker is not a liquid
Clinker is not pyrophoric. It does not ignite within
five minutes after coming into contact with air.

Argumentation
Clinker is not a liquid
Clinker is not oxidising as it does not cause or
contribute to the combustion of other materials.
Clinker is not an organic substance and it does
not contain the bivalent –O-O– structure
Portland cement clinker is not corrosive to steel.
Steel is used as concrete reinforcement element
and it is commonly known that cement protects
the steel by passivation. Portland cement clinker
is the main ingredient of cement.
Portland cement clinker is not corrosive to
aluminium, but the extract water from a 1:1
ground clinker mixture did cause more than
13.5% of mass loss in aluminium specimens.
Therefore, wet Portland cement mixtures should
not be brought into contact with aluminium.
P. 185 of the guidance document on the CLP
application states that the testing procedure for
this endpoint, in particular for solids which
become liquids, requires further work by the
Committees in charge of developing test
methods under the UN GHS program.

Argumentation
No causal association has been established
between Portland cement exposure and cancer.
The epidemiological literature does not support
the designation of Portland cement as a
suspected human carcinogen
Portland cement is not classifiable as a human
carcinogen (According to ACGIH A4: Agents
that cause concern that they could be
carcinogenic for humans but which cannot be
assessed conclusively because of a lack of data.
In vitro or animal studies do not provide
indications of carcinogenicity that are sufficient
to classify the agent with one of the other
notations.).
Portland cement contains over 90% Portland
cement clinker
No evidence from human experience
Portland Cement clinker dust may irritate the
throat and respiratory tract. Coughing, sneezing,
and shortness of breath may occur following
exposures in excess of occupational exposure
limits.
Overall, the pattern of evidence clearly indicates
that occupational exposure to cement dust has
produced deficits in respiratory function.
However, evidence available at the present time
is insufficient to establish with any confidence
the dose-response relationship for these effects.

(4) Final report Sediment Phase Toxicity Test Results with
Corophium volutator for Portland clinker prepared for
Norcem A.S. by AnalyCen Ecotox AS, 2007.
Ecotoxicological tests with Portland cement on
Daphnia magna (1) and Selenastrum coli (2)
have shown little toxicological impact. Therefore
LC50 and EC50 values could not be determined
(3). There is no indication of sediment phase
toxicity (4).
