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.
In June 2023, the Conference of the Parties adopted decision SC-11/1, which noted that as there are no longer any Parties registered for specific exemptions for the production and use of short-chain chlorinated paraffins from 18 December 2023, no new registrations may be made with respect thereto as of that date.
