Anhydrous ammonia fertilizer inspection is a critical quality control process conducted at various stages of the logistics chain. It minimizes trade risks by ensuring that cargo meets agreed specifications, is delivered in the correct quantity, and includes all required documentation for export and import operations.

CISS GROUP provides anhydrous ammonia fertilizer inspection services to leading agribusinesses and international trading companies at intermediate storage warehouses, elevators, factories, and ports worldwide.

Anhydrous ammonia is the most concentrated nitrogen fertilizer, containing over 80% nitrogen. It is a colorless liquid with a pungent odor, boiling violently in air at 33°C and evaporating rapidly at -77°C. Ammonia exists in liquid and gaseous states, with pure ammonia referred to as liquid ammonia. Storage, transportation, and application require pressure containment, typically in vessels with a working pressure of up to 16 atmospheres. All operations involving anhydrous ammonia are classified as hazardous, and the temperature at the flange connecting the loading line and tanker must not exceed -31.5°C.

CISS GROUP’s accredited inspectors and laboratory technicians conduct anhydrous ammonia fertilizer inspections throughout the supply chain.

The main stages of anhydrous Ammonia fertilizer inspection:

Incoming and outgoing anhydrous ammonia fertilizer inspection

Inspection occurs during delivery at ports or upon export from factory warehouses. CISS GROUP inspectors assess the condition of technological equipment, shipping containers, ventilation systems, and storage facilities. In existing warehouses, the maximum filling level of isothermal tanks must not exceed 80%. Cylinders containing liquefied anhydrous ammonia are labeled with data on content and batch identification.

Container and vessel hold cleanliness inspection before loading

A thorough visual inspection ensures that containers and vessel holds are clean and suitable for transporting anhydrous ammonia fertilizer. Inspectors examine internal surfaces, verify the integrity of locks, hinges, rubber seals, and fasteners, ensuring compliance with safety and transportation requirements.

Loading supervision and anhydrous ammonia fertilizer sampling

During loading, inspectors oversee operations, verify gross and net weight through re-weighing or volumetric measurement, and ensure adherence to transport safety guidelines. For liquefied anhydrous ammonia in cylinders, three cylinders are sampled for batches under 200 cylinders, with additional sampling for larger batches. For ammonia transported in tanks, samples are taken from at least three tanks or each tank if fewer than three are in the batch. When transported through ammonia pipelines, samples are collected at least once per shift. Samples may also be taken from storage tanks or designated sampling units at manufacturing and port facilities.

CISS GROUP provides 24/7 loading inspection and sampling services.

Laboratory analysis of anhydrous ammonia fertilizer quality

Quality testing is conducted in accredited laboratories following international standards and national methodologies (ISO, CEN, TFI – The Fertilizer Institute). Standard quality parameters analyzed include:

• Molecular weight
• Density
• Mass fraction of ammonia
• Mass fraction of nitrogen
• Mass fraction of water
• Mass concentration of oil
• Mass concentration of iron
• Mass fraction of total chlorine
• Mass fraction of carbon monoxide

Photo and video documentation

Each stage of the inspection is recorded with time-stamped photos and videos. A comprehensive photo report is provided upon completion, documenting all inspection and control stages.

Certification and documentation

Upon completion of the inspection, a final certificate or detailed report is issued. Clients can verify document authenticity using a unique QR code, providing direct access to the CISS GROUP website where PDF versions of certificates are securely stored. Our certificates are digitally signed with cryptographic protection, ensuring document integrity and security.

Digitally signed certificates are often required by financial institutions when processing trade finance transactions, such as letters of credit, to verify compliance and trade integrity.
