Specific Exemptions

To enable Parties to the Convention to take measures to reduce or eliminate releases of POPs from intentional production and use, for which alternatives do not exist yet or are not readily available, the Convention allows Parties to register specific exemptions for a specific period of time. Annexes A and B to the Convention describe specific exemptions, as well as acceptable purposes, that are available with respect to the relevant POPs. 

Parties may register for specific exemptions listed in Annex A or B pursuant to paragraph 3 of Article 4. These specific exemptions have a limited timeframe and shall expire five (5) years after the date of entry into force of the Convention with respect to that particular chemical (paragraph 4 of Article 4), unless an earlier date is indicated in the Register by the Party or an extension is granted by the Conference of the Parties under paragraph 7 of Article 4.

Register of Specific Exemptions

The Register of specific exemptions was established in conformity with Article 4 of the Stockholm Convention, for the purpose of identifying the Parties that have specific exemptions listed in Annex A or Annex B;

The Register is regularly updated after decisions adopted by the Conference of the Parties so as to include specific exemptions available following adoption of amendments to annexes to the Convention, as well as to take into account expired specific exemptions. Following decisions of the Conference of the Parties, no new registrations may be made with respect to certain specific exemptions. For further information, please see the Expired Specific Exemptions.

Dates of entry into force of the amendments to Annexes to the Convention

An indicative table on the status and entry into force of the amendments to the Annexes is available in the Amendments to Annexes to the Stockholm Convention page.


Specific exemptions for chemicals listed in Annexes A and B

Various specific exemptions and acceptable purposes have been made available to Parties within the Convention text and subsequently by decisions adopted by the Conference of the Parties to amend the Annexes to the Convention.

The lists below do not include those specific exemptions that have expired. Further information on these is available here.
