Urea inspection is a process of quality control of goods at different stages of logistic chain, which minimizes major trade risks related to the likelihood of cargo delivered or received not according to agreed specification, not being supplied in agreed quantity or incomplete set of accompanying documents agreed between parties for urea export/import operations is issued and received.

CISS GROUP provides urea inspection services to large agribusinesses and international trading companies in intermediate storage warehouses, elevators, factories or ports around the world.

The special feature of urea inspection is that it is a granular fertilizer, which contains 46% nitrogen. That is, it is the most concentrated nitrogen fertilizer that is used for horticultural crops. This substance is odorless and readily soluble in water. Moreover, as the temperature rises, its solubility increases. Fertilizer belongs to non-toxic compounds. Urea is very hygroscopic, so it should be stored in a dry and ventilated room, with an air humidity of no more than 50%. It is permissible to store urea in more humid rooms, but in a hermetically sealed container. Usually, the guaranteed shelf life is only six months, since the manufacturer guarantees the absence of caking of urea during this period, but then before use, in case of caking, it must be crushed and then used for an unlimited period of time. However, one must take into account the fact that over the years the amount of nitrogen in urea decreases slightly.

Accredited inspectors and laboratory technicians from CISS GROUP carry out urea inspection at any point of the supply chain.

The main stages of urea inspection:

Incoming/outgoing urea inspection.

It is carried out during delivery of urea to silos or to a port, or at releasing it from factory/silo warehouses. The CISS GROUP inspector will visually assess the condition of the premises for the suitability for cargo storage; will check the cargo itself so that it is dry, not mixed with other cargo, not damp or wet, free from pests, foreign matter, weeds, mold or foreign odors. If urea is delivered in bags, the inspector will inspect them for traces of soaking, and if agreed, will perform the selected bag opening for sampling purpose and further visual check of cargo quality.

Acceptance of cleanliness containers / holds of vessels before loading urea.

This is a visual inspection of containers and empty holds for their cleanliness and suitability for urea transportation. The inspector carefully examines their internal surfaces, checks the integrity and condition of locks, hinges and other fasteners on the container doors, rubber seals for container doors and hold covers.

Visual control of the loading process and sampling of urea.

During loading, the inspector controls the loading of urea, confirms the gross / net weight during re-weighing; in the case of loading urea into the holds - the initial, intermediate and final check of the weight of the loaded cargo by the draft survey method, controls the fumigation process; conducts a visual assessment of the quality of the cargo, takes samples in accordance with sampling rules, forms composite samples. At the end of the loading, the inspector will seal the loaded containers or holds. He enters all the data into reports to which the client gets direct access. Note that the CISS GROUP loading inspection and sampling can be carried out around the clock on 24/7 basis.

Laboratory analyzes of urea quality.

We check the quality of urea exclusively in accredited laboratories in accordance with international standards and national methods (ISO, CEN, TFI (The Fertilizer Institute)) and others. The determined standard indicators of urea quality include: moisture, mass fraction of nitrogen, mass fraction of biuret, mass fraction of free ammonia.

In addition to basic analyzes, laboratory analyses can determine the urea friability, particle size distribution and static strength of granules.

Photo and video report.

The inspector records each stage of the inspection with photos and videos. All such data contain the date and time of recorded stage of inspection. At the end of the urea inspection, CISS GROUP provides a detailed photo report of all stages of control and inspection.


Based on the results of the urea inspection the final certificate or reports are issued. The client can check the authenticity of the documents using a unique QR code, which is the "key" to the CISS GROUP website, where pdf versions of certificates are stored. Our certificates are protected with a digital cryptographic signature, which also guarantees their reliability and security.

Digitally signed certificates are often required by banks to verify the integrity of trading process when financing trade operations in the form of a letter of credit.
