UAN solution inspection (urea and ammonium nitrate)
UAN solution (urea and ammonium nitrate) inspection is a critical quality control process conducted at various stages of the logistics chain. It mitigates major trade risks associated with discrepancies in cargo specifications, quantity shortages, or incomplete documentation during UAN solution export and import operations.
CISS GROUP provides UAN solution (urea and ammonium nitrate) inspection services to large agribusinesses and international trading companies at intermediate storage warehouses, elevators, factories, and ports worldwide.
Special storage tanks are used for UAN solution (urea and ammonium nitrate), specifically designed for aqueous ammonia and liquid complex fertilizers. Transportation is carried out in specialized units adapted for liquid fertilizers. UAN solution contains minimal free ammonia, reducing nitrogen losses during loading, transportation, storage, and application. Its low crystallization and freezing point enable year-round storage and transport. Any temporary freezing in storage tanks is reversible, as crystals dissolve with rising temperatures, fully restoring the fertilizer’s properties.
Accredited inspectors and laboratory technicians from CISS GROUP conduct UAN solution (urea and ammonium nitrate) inspections at every point in the supply chain.
The main stages of UAN solution inspection:
Incoming/outgoing UAN solution inspection
This stage takes place when UAN solution is delivered to the port or removed from factory storage facilities. CISS GROUP inspectors visually assess the condition of collectors made of carbon or alloy steel, including specialized railway tanks and road tankers, ensuring the tightness of their hatches.
Cleanliness inspection of containers and vessel holds before loading
A visual inspection of tanks and empty holds ensures cleanliness and suitability for UAN solution transportation. Inspectors examine internal surfaces, verify the integrity of fasteners and rubber seals, and confirm compliance with safety standards.
Loading supervision and sampling
During loading, inspectors monitor the process, verify gross and net weight through re-weighing, and perform weight checks for bulk cargo using the draft survey method. They oversee fumigation, conduct visual quality assessments, and collect samples per regulatory sampling procedures. Once loading is complete, containers or holds are sealed, and comprehensive reports are generated with direct client access.
CISS GROUP provides 24/7 loading inspection and sampling services.
Laboratory analysis of UAN solution quality
UAN solution quality testing is performed exclusively in accredited laboratories according to international standards and national methodologies (ISO, CEN, TFI). Key quality parameters include:
- Total nitrogen mass fraction
- Urea mass fraction
- Ammonium nitrate mass fraction
- Crystallization temperature
- Freezing point
- pH level
- Density
Photo and video documentation
Each inspection stage is documented with photos and videos, including timestamps. Upon completion, CISS GROUP provides a comprehensive photo report covering all aspects of the inspection.
Certificates and Documentation
Following UAN solution inspection, a final certificate or detailed report is issued. Clients can verify document authenticity using a unique QR code linked to the CISS GROUP website, where digital certificates are securely stored. These certificates feature a digital cryptographic signature, ensuring authenticity and security.
Digitally signed certificates are often required by banks for verifying trade integrity in transactions involving letters of credit.
CISS GROUP ensures transparency, reliability, and compliance in every UAN solution inspection, safeguarding the interests of all stakeholders in the global supply chain.
