INTRODUCTION AND CONTEXT 

for 

the 

fourteenth 

time 
European  Parliament  and  Council  Directive 94/60/EC  amending 
Directive 76/769/EEC  of  27 July  1976  on  the  approximation  of  the  laws,  regulations  and 
administrative  provisions  of  the  Member  States  relating  to  restrictions  on  the  marketing  and  use  of 
certain dangerous substances and preparations1 introduced a list of substances classified as category 1 
or  2  carcinogen,  mutagen  or  toxic  to  reproduction  (c/m/r)  in  the  Appendix  of  Annex I  to 
Directive 76/769/EEC. It stipulates in points 29, 30 and 31 of Annex I of Directive 76/769/EEC that 
these substances  may not be used in substances or preparations placed on the  market for  sale to the 
general  public.  These  are  substances  which  have  previously  been  listed  as  carcinogen,  mutagen  or 
toxic  to  reproduction  (c/m/r)  in  Annex I  of  Council  Directive 67/548/EEC  of  27 June  1967  on  the 
approximation  of  the  laws,  regulations  and  administrative  provisions  relating  to  the  classification, 
packaging  and  labelling  of  dangerous  substances2.  Annex  I  of  Directive  67/548/EEC  is  regularly 
updated by way of adaptations to technical progress. 

Directive 94/60/EC  also  provides  that  the  Commission  will  submit  to  the  European  Parliament  and 
Council, no later than six months after publication of an adaptation to technical progress of Annex I to 
Council Directive 67/548/EEC, a proposal for a Directive governing the substances newly classified as 
carcinogenic, mutagenic and toxic to reproduction in categories 1 and 2, so as to update the Appendix 
of Annex I to Directive 76/769/EEC. 

Commission  Directive 2004/73/EC  of  29  April  2004  adapting  to  technical  progress  for  the 
twenty-ninth time Council Directive 67/548/EEC3, and more particularly Annex I thereto, inserted 146 
entries  containing  substances  newly  classified  as  carcinogenic  category 1,  21  entries  containing 
substances  newly  classified  as  carcinogenic  category 2,  152  entries  containing  substances  newly 
classified as  mutagenic category 2, and 24 entries  containing substances newly classified as toxic to 
reproduction category 2 in Annex I of Directive 67/548/EEC. It is proposed to update the Appendix of 
Annex I  to  Directive 76/769/EEC  in  order  to  govern  these  substances  newly  classified  in  the 
framework of Directive 67/548/EEC. 

This  twenty-ninth  amendment  will  insert  346  entries  containing  substances  newly  classified  or  re-
classified  under  Commission  Directive 2004/73/EC  in  the  Appendix  of  Annex I  to  Directive 
76/769/EEC. However, among these 346 entries, 304 contain substances which were already subject to 
a restriction for sale to the general public due to an earlier classification as c/m/r substance of category 
1 or 2. Therefore, only 42 of these entries relate to substances that will be subject for the first time to 
the restriction for sale to the general public provided in points 29, 30 and 31 of Annex I of Directive 
76/769/EEC. 

Among the 146 entries containing substances newly classified as carcinogenic category 1, 145 cover 
substances which were previously classified as carcinogenic category 2. Therefore, the list relating to 
carcinogens category 2 needs to be amended accordingly.

2. 

JUSTIFICATION FOR PROPOSAL AND CONSIDERATIONS OF SUBSIDIARITY 

What are the objectives of the proposal in relation to the Community’s obligations? 

Within the framework for action in the field of public health, the European Parliament and the Council 
have  adopted  an  action  plan  to  combat  cancer  (Decision  No 646/1996/EC4  and  Decision  No 
1786/2002/EC5).  In  this  context,  the  Community  is  committed  to  promoting  and  improving  health, 
preventing  disease,  and  countering  potential  threats  to  health,  with  a  view  to  reducing  avoidable 
morbidity  and  premature  mortality  and  activity-impairing  disability.  Due  to  the  fact  that  use  by 
consumers of substances classified as carcinogenic, mutagenic or toxic to reproduction of category 1 
or  2  cannot  be  controlled,  safety  can  only  be  ensured  by  governing  these  substances  through 
restrictions on the placing on the market of substances and preparations containing c/m/r substances. 

Following  the  adoption  of  Directive 94/60/EC  the  Commission  is  invited  to  propose  directives 
restricting the use by the general public of substances newly classified as c/m/r categories 1 or 2. 

The  aim  of  the  proposal  is  to  preserve  the  Internal  Market.  When  Member  States  adopt  national 
provisions restricting the marketing and use of dangerous substances and preparations, including c/m/r 
substances  and  preparations,  there  will  be  obstacles  to  trade  because  of  differences  in  legislation 
between  Member  States.  This  Proposal  aims  to  improve  the  conditions  for  the  functioning  of  the 
Internal Market to the benefit of the protection of the health and safety of consumers. 

Do the initiatives arise out of an exclusive Community competence or a shared competence? 

The action to preserve the Internal Market for dangerous substances and preparations falls within the 
exclusive  competence  of  the  Community.  This  competence  was  established  by  Council  Directive 
76/769/EEC. 

What are the courses of action available to the Community? 

The  only  course  of  action  available  is  to  put  forward  a  proposal  for  an  amendment  to 
Directive 76/769/EEC, the twenty-ninth amendment, providing for harmonised rules governing the use 
of substances classified as c/m/r categories 1 or 2 by restricting the placing on the market for sale to 
the general public of substances or preparations containing such c/m/r substances.

Decision No 646/96/EC of the European Parliament and of the Council of 29 March 1996 adopting an 
action  plan  to  combat  cancer  within  the  framework  for  action  in  the  field  of  public  health 
(1996 
to  2000)  (OJ  L 95,  16.4.1996,  p. 9),  as  amended  by  Decision  No  521/2001/EC

Are  uniform  rules  necessary?  Is  it  not  sufficient  to  establish  targets  to  be  implemented  by  Member 
States? 

The  proposed  twenty-ninth  amendment  establishes  uniform  rules  for  the  use  of  substances  newly 
classified as c/m/r category 1 or 2 by restricting the placing on the market for sale to the general public 
of substances or preparations containing such c/m/r substances. It therefore guarantees a high level of 
protection of health and safety of consumers. The proposed twenty-ninth amendment is the only way 
to meet these goals. Targets would be insufficient. 

3. 

RATIONALE OF THE PROPOSAL 

The proposed twenty-ninth amendment would govern the substances newly classified or re-classified 
as  c/m/r  category 1  or  category 2  in  the  twenty-ninth  adaptation  to  technical  progress  of 
Directive 67/548/EEC by inserting them in the Appendix of Annex I to Directive 76/769/EEC in order 
to restrict their use in substances and preparations placed on the market for sale to the general public. 

4. 

COSTS AND BENEFITS 

4.1. 

Costs 

Concerning  the  substances  newly  classified  as  carcinogen,  mutagen  or  toxic  to  reproduction  of 
category 1 or 2 in the twenty-ninth adaptation to technical progress of Directive 67/548/EEC, the costs 
are estimated to be low due to the limited use of those substances by the general public. According to 
available  information,  a  large  number  of  these  newly  classified  c/m/r  substances  are  used  as  raw 
material, organic synthesis intermediates or for specific professional applications. 

In  addition,  most  of  the  substances  listed  in  the  proposed  twenty-ninth  amendment  were  already 
subject  to  a  restriction  for  sale  to  the  general  public  due  to  their  previous  classification  as  a  c/m/r 
substance of  category 1 or 2 and are just been subject to reclassification or have been ascribed new 
notes.  In  practice,  only  42  of  the  346  entries  containing  substances  newly  classified  will  relate  to 
substances that will be subject to new restrictions for sale to the general public. 

The proposal is cost-effective since it will ensure that consumer health is protected more effectively 
without having any significant impact in economic terms and in terms of job losses, given that use of 
these dangerous substances by the general public is limited. 

4.2. 

Benefits 

Concerning the 42 entries containing substances newly classified as carcinogen, mutagen or toxic to 
reproduction,  the  proposed  restriction  for  sale  to  the  general  public  will  ensure  that  the  substances 
classified as carcinogenic, mutagenic and toxic to reproduction of categories 1 and 2 are not used in 
substances  and  preparations  placed  on  the  market  for  sale  to  the  general  public.  The  benefit  of  the 
proposal is an increased level of protection for consumers. 

5. 

PROPORTIONALITY 

Directive  94/60/EEC  provides  that  the  proposal  from  the  Commission  for  a  Directive  governing  the 
substances newly classified as carcinogenic, mutagenic and toxic to reproduction in categories 1 and 2 
will  take  account  of  the  risks  and  advantages  of  the  substances  newly  classified  as  well  as  of  the 
Community legislative provisions on risk analysis.

In  the  elaboration  of  this  proposal,  the  Commission  has  sought  all  available  information  concerning 
the  uses  of  these  substances  covered  in  order  to  find  the  right  balance.  In  this  context,  it  should  be 
recalled that most of these substances were already subject to a restriction for sale to the general public 
due to their previous classification as a c/m/r substance of category 1 or 2 and are just been subject to a 
re-classification or have been ascribed new notes. Therefore, the present proposal does not have any 
impact. 

Concerning the remaining substances (contained in 42 of the 346 entries) which were not previously 
subject  to  the  restriction  for  use  in  substances  and  preparations  placed  on  the  market  for  sale  to  the 
general public established in points 29, 30 and 31 of Annex I of Directive 76/769/EEC, according to 
the available information and the outcome of the consultation of stakeholders, it appears that a large 
number  of  these  substances  are  used  as  raw  material,  organic  synthesis  intermediates  or  for  specific 
professional applications rather than in substances  and preparations placed on the  market for sale to 
the general public and that there is no need for specific derogation in the present proposal. 

Therefore, the twenty-ninth amendment would yield benefits in terms of protecting human health and 
the environment. This will be achieved at low cost. 

6. 

CONSULTATIONS PERFORMED IN PREPARING THE DRAFT TWENTY-NINTH 
AMENDMENT 

A  number  of  organisations  have  been  consulted,  inter  alia  CEFIC  (European  Chemical  Industry 
Council), the CONCAWE (Conservation of Clean Air and Water in Europe), Eurometaux (European 
association of metals) and BLIC (European association of the rubber industry) as well as the European 
Consumer’s organisation (BEUC). The experts from Member States were consulted on 15 July 2004. 

7. 

CONFORMITY WITH THE TREATY 

This proposal is intended to preserve the Internal Market and at the same time ensure a high level of 
protection  of  health  of  the  consumers  and  of  the  environment  and  is  therefore  in  conformity  with 
Article 95(3) of the Treaty. 

8. 

EUROPEAN PARLIAMENT AND ECONOMIC AND SOCIAL COMMITTEE 

In compliance with Article 95 of the Treaty, the co-decision procedure with the European Parliament 
is applicable. The Economic and Social Committee has to be consulted.

The substances which appear in Annex I to Council Directive 67/548/EEC of 27 June 
1967  on  the  approximation  of  the  laws,  regulations  and  administrative  provisions 
relating  to  the  classification,  packaging  and  labelling  of  dangerous  substances10  and 
are classified as carcinogens category 1 or 2 may cause cancer. The substances which 
appear in Annex I to Directive 67/548/EEC and are classified as mutagens category 1 
or 2 may cause heritable genetic damages. The substances which appear in Annex I to 
Directive 67/548/EEC and are classified as toxic to reproduction category 1 or 2 may 
cause birth defects or may impair fertility. 

In  order  to  improve  human  health  protection  and  consumer  safety,  the  use  of 
substances  newly  classified  as  carcinogenic,  mutagenic  or  toxic  to  reproduction  of 
category 1 or 2 should be governed and the placing on the market of substances and 
preparations  containing  them  should  be  subject  to  restriction  for  sale  to  the  general 
public. 

Council  Directive  76/769/EEC  of  27  July  1976  on  the  approximation  of  the  laws, 
regulations and administrative provisions of the Member States relating to restrictions 
on  the  marketing  and  use  of  certain  dangerous  substances  and  preparations11  lays 
down  restrictions  on  the  marketing  and  use  of  certain  dangerous  substances  and 
preparations,  with  the  objective,  among  others,  to  improve  human  health  protection 
and consumer safety. 

Directive 94/60/EC  of  the  European  Parliament  and  of  the  Council  of  20 December 
1994 amending for the 14th time Directive 76/769/EEC12 establishes, in the form of an 
Appendix of Annex I to Directive 76/769/EEC, a list containing substances classified 
as  carcinogenic,  mutagenic  or  toxic  to  reproduction  of  category 1  or  2.  Such 
substances and preparations containing them should be subject to restriction for sale to 
the general public. 

Directive 94/60/EC  provides  that  the  Commission  will  submit  to  the  European 
Parliament  and  Council,  no  later  than  six  months  after  publication  in  the  Official 
Journal  of  the  European  Union  of  an  adaptation  to  technical  progress  of  Annex  I  to 
Council Directive 67/548/EEC, which contains substances classified as carcinogenic, 
mutagenic  or  toxic  to  reproduction  in  category  1  or  2,  a  proposal  for  a  directive 
governing these newly classified substances, so as to update the Appendix of Annex I 
to Directive 76/769/EEC. Such proposal from the Commission will take account of the 
risks and advantages of the newly classified substances as well as of the Community 
legislative provisions on risk analysis.

Commission Directive 2004/73/EC of 29 April 2004 adapting to technical progress for 
the twenty-ninth time Council Directive 67/548/EEC13, and more particularly Annex I 
thereto,  includes  146  entries  containing  substances  newly  classified  as  carcinogenic 
category 1,  21  entries  containing  substances  newly  classified  as  carcinogenic 
category 2, 152 entries containing substances newly classified as mutagenic category 2 
and  24  entries  containing  substances  newly  classified  as  toxic  to  reproduction 
category 2. 

Commission Directive 2004/73/EC also amends the notes relating to the identification, 
classification  and  labelling  ascribed  to  four  substances  classified  as  carcinogenic 
category 1, 36 entries containing substances classified as carcinogenic category 2, six 
entries  containing  substances  classified  as  mutagenic  category 2,  two  entries 
containing  substances  classified  as  toxic  to  reproduction  category 1  and  three  entries 
containing  substances  classified  as  toxic  to  reproduction  category 2.  The  lists  in  the 
Appendix of Annex I to Directive 76/769/EEC should be amended accordingly. 

The risks and advantages of the newly classified substances, by Directive 2004/73/EC, 
as  carcinogenic,  mutagenic  and  toxic  to  reproduction  of  category 1  or  2  have  been 
taken  into  account,  in  particular  those  relating  to  the  substances  which  were  not  yet 
subject to a restriction for use in substances and preparations placed on the market for 
sale to the general public (due to an earlier classification). This analysis concluded that 
these  newly  classified  substances  could  be  inserted  in  the  Appendix  of  Annex I  to 
Directive 76/769/EEC.

ANNEX 

1. 

(a) 

The heading “Notes” of the Foreword is amended as follows: 

The following notes are inserted: 

“Note A: 

The name of the substance must appear on the label in the form of one of the designations given in 
Annex I of Directive 67/548/EEC (see Article 23(2)(a)). 

In  Annex  I  of  Directive  67/548/EEC,  use  is  sometimes  made  of  a  general  description  such  as 
‘…compounds’  or  ’…salts’.  In  this  case,  the  manufacturer  or  any  other  person  who  markets  such  a 
substance  is  required  to  state  on  the  label  the  correct  name,  due  account  being  taken  of  the  chapter 
entitled ‘Nomenclature’ of the Foreword. 

Directive  67/548/EEC  also  requires  that  the  symbols,  indications  of  danger,  R-  and  S-phrases  to  be 
used for each substance shall be those shown in Annex I (Article 23(2)(c), (d) and (e)). 

For  substances  belonging  to  one  particular  group  of  substances  included  in  Annex  I  of  Directive 
67/548/EEC, the symbols, indications of danger, R- and S-phrases to be used for each substance shall 
be those shown in the appropriate entry in that Annex I. 

For  substances  belonging  to  more  than  one  group  of  substances  included  in  Annex  I  of  Directive 
67/548/EEC, the symbols, indications of danger, R- and S-phrases to be used for each substance shall 
be  those  shown  in  both  the  appropriate  entries  given  in  Annex  I.  In  cases  where  two  different 
classifications are given in the two entries for the same hazard, the classification reflecting the more 
severe hazard classification is used.” 

“Note D: 

Certain  substances  which  are  susceptible  to  spontaneous  polymerisation  or  decomposition  are 
generally placed on the market in a stabilised form. It is in this form that they are listed in Annex I to 
Directive 67/548/EEC.
