Upcoming EU active substance renewal submission deadlines

Apply for active substance renewal by the relevant deadlines to keep products on the NI market.

Under the EU Biocidal Products Regulation (EU BPR), active substance approvals will expire unless a renewal application is submitted to ECHA at least 550 days before their expiry date.

The 550-day deadlines are coming up for the following active substance/product type combinations under EU BPR. This affects NI:

28 October 2026

• calcium dihydroxide / calcium hydroxide / caustic lime / hydrated lime / slaked lime (CAS 1305-62-0 EC 215-137-3) in product types 2 and 3
• calcium magnesium oxide / dolomitic lime (CAS 37247-91-9 EC 253-425-0) in product types 2 and 3
• calcium magnesium tetrahydroxide / calcium magnesium hydroxide / hydrated dolomitic lime (CAS 39445-23-3 EC 254-454-1) in product types 2 and 3
• calcium oxide / lime / burnt lime / quicklime (CAS 1305-78-8 EC 215-138-9) in product types 2 and 3
• chlorocresol (CAS 59-50-7 EC 200-431-6) in product types 1, 2, 3, 6, 9, and 13

Any person, company or task force/consortium can support an active substance/product type combination for renewal – it doesn’t have to be the original supporter.

Check the EU Article 95 List to see who the original supporters were.

If any of these active substance/product type combinations are important to you, consider contacting your supplier to let them know.

If a renewal application is not submitted for the above active substance/product type combinations under EU BPR, the approvals will expire. This means the active substances will no longer be able to be used in biocidal products of the relevant product types in NI.

In addition, articles treated with such products will no longer be able to be placed on the market in NI.
