What happened
The European Commission issued Implementing Decision (EU) 2026/2127 on 24 September 2026. It postpones when EU approval for 2-methylisothiazol-3(2H)-one ends in relation to biocidal products classified as product type 13.
The measure was adopted under Regulation (EU) No 528/2012, the EU Biocidal Products Regulation. The Official Journal notice supplied does not identify the newly scheduled expiry date.
Why it matters
The decision changes the approval timetable for the named active substance within the relevant product category. Businesses that manufacture, place on the market, supply or use affected product-type 13 biocidal products should review their product portfolios and regulatory records against the decision.
Teams should also obtain and assess the full decision where they need confirmation of the revised timing or any related conditions. The available notice does not provide transition arrangements or further compliance deadlines.
What to do next
Confirm whether 2-methylisothiazol-3(2H)-one is relevant to product-type 13 products in scope, and retain the decision reference in regulatory monitoring records. Check the Official Journal publication for the updated expiry date and any additional detail.
