Overview

What Is AdBlue® and Why Does Your Fleet Need It?

AdBlue® is a 32.5% high-purity urea solution in deionised water, used in Selective Catalytic Reduction (SCR) systems fitted to Euro 4, Euro 5, and Euro 6 diesel engines. The SCR system injects AdBlue® into the exhaust stream, converting harmful nitrogen oxides (NOx) into harmless nitrogen and water vapour — reducing NOx by up to 90%.

Also known as Diesel Exhaust Fluid (DEF) or AUS 32, AdBlue® is legally mandated for SCR-equipped vehicles under Singapore’s NEA emission standards and international regulations. Running without AdBlue® will trigger engine derate or complete shutdown on Euro 5 and Euro 6 vehicles.

The critical risk most fleet operators underestimate: not all AdBlue® is created equal. Substandard or contaminated fluid can permanently damage SCR catalysts, void manufacturer warranties, and trigger failed emission inspections. ISO 22241 certification is the only reliable protection.

Certification

ISO 22241 — Why It Matters

ISO 22241 is the international standard governing AdBlue® quality, handling, storage, and transportation. Non-compliant AdBlue® can cause:

  • SCR catalyst damage — Impurities foul or destroy the catalyst substrate. Replacement costs thousands of dollars per vehicle.
  • Engine derating — Modern ECUs reduce engine power when quality sensors detect out-of-spec fluid, causing immediate operational disruption.
  • Voided OEM warranty — Major engine manufacturers explicitly void warranties when damage is caused by non-ISO 22241 AdBlue®.
  • Failed emission inspections — SCR systems running on degraded fluid will fail Singapore’s periodic emission checks.

Interion supplies ISO 22241-certified AdBlue® with full batch traceability and compliance documentation on every delivery.

AdBlue® Quality Testing Service

Interion Differentiator

Singapore’s only AdBlue® supplier offering independent quality testing for existing stock

If you suspect contamination, have inherited old stock, or are changing suppliers, Interion can test your AdBlue® before it enters your fleet — protecting your SCR systems without downtime.

The quality testing service checks:

  • Urea concentration — Must be 31.8–33.2% by weight per ISO 22241. Too low reduces NOx conversion; too high risks crystallisation and sensor damage.
  • Purity and contaminants — Tests for metals, anions, aldehydes, and impurities that damage catalysts at parts-per-million concentrations.
  • Appearance and clarity — Cloudiness, discolouration, or particulates indicate degradation, bacterial growth, or cross-contamination.

When to use it: inherited stock of unknown origin; suspect tank contamination; AdBlue® past stated shelf life; fleet compliance audit; supplier change verification.

Contact Interion to arrange sample collection or drop-off. Results provided with a written report suitable for compliance records.

FAQ

Frequently Asked Questions

AdBlue® is a 32.5% aqueous urea solution — high-purity urea dissolved in deionised water. The exact concentration (31.8–33.2% by weight) is defined by ISO 22241-1. It uses pharmaceutical-grade urea, not agricultural urea, which contains impurities incompatible with SCR systems.
AdBlue® has an 18-month shelf life when stored at 15–25°C, away from direct sunlight. Signs of degradation include cloudiness, crystallisation, an ammonia-like smell, or discolouration. Interion’s quality testing service can verify concentration and contamination before the fluid enters your vehicles.
No. Only ISO 22241-compliant AdBlue® (AUS 32) should be used. Agricultural fertiliser urea and other urea-based products contain impurities — including biuret, aldehydes, and metals — that destroy SCR catalysts within hours. Engine manufacturers explicitly void SCR-related warranties when damage is caused by non-compliant fluid.
Yes. Interion supplies marine-grade AUS 32 to vessel operators and port agents for onboard SCR systems compliant with IMO Tier III NOx requirements. We supply in drums and IBC tanks. Contact us for delivery scheduling and documentation.
Interion supplies from 5 L jerry cans (a single vehicle top-up) to bulk tanker delivery. There is no minimum order quantity for drum and IBC formats. Contact us directly for pricing by volume and format.
Contact Interion to arrange testing by sample drop-off or collection. We test urea concentration, purity, and contamination markers against ISO 22241-1 specification. A written test report is provided within 2–3 working days, suitable for compliance audits or warranty records.
