In 2023 and 2025, Annex A to the Convention was amended by decisions on listing of UV-328 (decisions SC-11/11; SC-12/14). In addition to listing this chemical in Annex A (Elimination) with certain specific exemptions, the Conference of the Parties also adopted an additional decision on UV-328 (decision SC-12/15).
By Decision SC-12/15, the Conference of the Parties requested any Party making use of the specific exemptions for water-seal tape for insulation blankets and decking on aircraft; and polyurethane and polyamide adhesives, and polyurethane coatings, for structural, mechanical, interior and electrical assemblies, and emergency, propulsion, environmental control, and flight control systems, on aircraft to report annually to the Secretariat on relevant information, including, as feasible, quantities used, specific application and progress towards phase-out, using the best available scientific and technical evidence.
The table below reflects the information reported to the Secretariat by Parties pursuant to decision SC-12/15.
