ISO 22241 Compliance: Why It Matters for Your Business

February 2024
5 min read

ISO 22241 certification isn't just a label—it's your guarantee that AdBlue® meets the strict purity and quality standards required for modern diesel engines. Using non-compliant product can void warranties and cause expensive damage. Here's why certification matters.

What is ISO 22241?

ISO 22241 is an international standard that defines the quality requirements for Diesel Exhaust Fluid (AdBlue®). It specifies exact composition, purity levels, and testing procedures that manufacturers must follow.

The Standard Covers:

  • Urea concentration: Must be exactly 32.5% (±0.7%)
  • Purity levels: Maximum allowable contaminants (metals, aldehydes, etc.)
  • Physical properties: Density, refractive index, alkalinity
  • Biuret content: Must be below 0.3%
  • Water quality: Deionized water with specific conductivity limits

Why Compliance is Critical

Prevents SCR System Damage

Contaminated or incorrect-concentration AdBlue® can crystallize in injectors, clog catalysts, and corrode sensors. Repairs can cost $5,000-$15,000+ per vehicle. ISO 22241-certified product eliminates this risk.

Protects Your Warranty

Most vehicle manufacturers require ISO 22241-certified AdBlue® to maintain warranty coverage. Using non-certified product voids warranty claims for SCR-related repairs. Always keep receipts and certificates.

Ensures Legal Compliance

Emissions regulations require proper SCR function. Using substandard AdBlue® that causes SCR failure can result in non-compliance fines, failed inspections, and vehicle de-registration.

Maximizes Performance & Efficiency

Correct-specification AdBlue® ensures optimal NOx reduction (up to 90%), maintains engine performance, and prevents excessive consumption or warning lights. Your fleet operates as designed.

VDA Licensing: An Additional Quality Mark

The VDA (Verband der Automobilindustrie - German Association of the Automotive Industry) operates a licensing program for AdBlue® manufacturers. VDA licensing includes:

Regular Testing

Independent laboratory testing of production batches to verify ISO 22241 compliance

Production Audits

On-site facility inspections ensuring proper manufacturing processes and quality controls

Certification Documents

Certificate of Analysis provided with every batch, showing test results and compliance

Trademark Protection

Right to use the "AdBlue®" trademark, signaling verified quality to customers

How to Verify AdBlue® Quality

What to Look For When Purchasing:

ISO 22241 Certification

Look for explicit ISO 22241 certification claims on packaging or documentation

VDA License Number

VDA-licensed manufacturers display their license number on products and documentation

Certificate of Analysis

Reputable suppliers provide batch-specific test results from NATA-accredited laboratories

Need Your Certificate of Analysis?

Enter your batch number and invoice number to request your COA

Red Flags: Signs of Non-Compliant Product

  • Unusually low prices (significantly below market rates)
  • No certification documentation or Certificate of Analysis available
  • Unclear or missing manufacturer information
  • Product labeled as "diesel exhaust fluid" without ISO 22241 certification
  • Unknown or expired production dates
  • Suspicious packaging or reused containers

Key Takeaways

  • ISO 22241 certification guarantees AdBlue® meets required purity standards
  • Non-compliant product can cause SCR damage costing $5,000-$15,000+ per vehicle
  • Using certified product protects warranty coverage and ensures legal compliance
  • VDA licensing adds another layer of quality assurance through independent testing
  • Always verify certification, check Certificates of Analysis, and avoid suspiciously cheap products
