ISO 18611 Certified — Singapore-Based Supply
Marine Urea Solution Supplier in Singapore
AUS40 marine urea solution delivered to your vessel in Singapore — drum, IBC, or Flexitank. MARPOL Tier III NOx compliance supply for offshore rigs, container liners, bulk carriers, and cargo vessels.
Why Marine Urea Matters
MARPOL Tier III NOx Compliance Starts with the Right AUS40
Vessels in Emission Control Areas must reduce NOx by up to 80% under MARPOL Annex VI Tier III. SCR systems require high-purity marine urea solution — substandard AUS40 damages catalysts and risks port detentions.
ISO 18611 & ISO 22241 Certified
Our AUS40 marine urea solution meets international purity standards for marine SCR catalytic reduction. Every batch tested and certified with full COA documentation.
Short Lead Times, Singapore-Based
Stock held in Singapore for rapid supply. Alongside berth, at anchor, or shore terminal delivery — coordinated to your vessel schedule.
Flexible Quantities & Packaging
25L drums for small vessels to 19,500L Flexitanks for large carriers. Bulk ISO tank containers also available on request.

Compliance Note
AUS40 vs AdBlue® — Not Interchangeable
Marine urea (AUS40) uses a 40% urea concentration to meet the dosing requirements of high-temperature marine SCR systems. AdBlue® (AUS32) is 32.5% urea for road vehicles.
Using AUS32 in a marine SCR system risks catalyst damage and NOx non-compliance. Always specify ISO 18611-grade AUS40 for your vessel.

FAQ
Common Questions About Marine Urea & AUS40 Supply
What is AUS40 marine urea solution and how does it differ from AdBlue®?
AUS40 is a 40% urea solution for marine SCR systems under MARPOL Tier III. AdBlue® (AUS32) is 32.5% for road vehicles. Higher urea concentration and different purity specifications make them non-interchangeable — using AUS32 in marine SCR systems risks catalyst damage. For road fleets, see AceRev AdBlue supplier Singapore.
What MARPOL regulation requires marine urea on vessels?
MARPOL Annex VI Tier III requires vessels built on or after 1 January 2016 operating in NOx Emission Control Areas to reduce NOx by ~80% vs Tier I. SCR systems dosed with AUS40 marine urea solution are the primary compliance method.
What quantities of marine urea can you supply and how quickly?
We supply AUS40 in 25L drums for small vessels through to 19,500L Flexitanks for large carriers. Singapore-stocked inventory typically enables 24–48 hour fulfilment for urgent orders. Advance scheduling is preferred for large bulk orders.
Is Seacrestor AUS40 compatible with all marine SCR brands?
Yes. Seacrestor AUS40 is certified to ISO 18611 and ISO 22241, compatible with MAN, Wärtsilä, Mitsubishi, and Caterpillar marine SCR systems. Batch test certificates are available on request with every delivery.
Do you supply marine urea outside Singapore?
