The compliant biocide market just narrowed with limited availability
The exclusion hits most of the market at once
Under the EU Biocidal Products Regulation, actives classified carcinogenic (Cat 1A/1B) are excluded from approval and the active the marine biocide market is overwhelmingly built on carries exactly that classification. This isn't one product; it's most of them.
There is still a compliant option available
FuelClear™ M15 is built on a different, non-carcinogenic active that sits outside the exclusion and it's held in EU stock, ready to ship. Stopping treatment isn't the answer either: where water meets fuel, microbes grow, blocking filters, corroding tanks and threatening reliability at sea.
The Fuel Biocide Market in 2026
The exlusion hits most of the market at once. Under the EU BPR, actives classified carcinogenic (Cat 1A/1B) are excluded from approval and the active most marine biocides are built on carries exactly that classification.
Untreated fuel fails, often at the worst moment. Stopping treatment isn't the answer. Where water meets fuel, microbes grow: blocked filters, corroded tanks, fouled injectors and, at sea, the risk of losing propulsion or power.
One compliant option remains available and in stock. FuelClear™ M15 uses a non-carcinogenic active that sits outside the exclusion. It's held in EU stock, ready to ship in days from Venlo (NL).
