The distinctiveness of sunflower inspection is due to highly hygroscopic nature of its crop - that is, the ability to absorb moisture from the air. This fact significantly affects the mass of products and even the loss of chemical and physical properties. The oil content of sunflower seeds is essential in quality determination. The self-heating of sunflower happens due to chemical hydrolysis of oil as a result of a complex chemical reactions. In such case, the temperature may rises to 200-300 ° C, which can lead to self-ignition. Since the hydrolysis process is accompanied by the formation of gases, which include hydrocarbons, it can further lead to an explosion by self-ignition. Another feature of sunflower is the oxidation of oil in the achene kernel resulting in temperatures rise to 28-29 ° C, when the acid number rises, and it is no longer possible to reduce it in the future. The acid number greatly affects the quality of sunflower oil. The described processes make the control of temperature one of the most important feature of proper process of sunflowers inspection.

FOSFA-accredited inspectors and laboratory technicians from CISS GROUP carry out sunflower inspection at any point of the supply chain.

Incoming/outgoing sunflower inspection.

It is carried out during delivery of sunflower 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 sunflower 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 sunflower.

This is a visual inspection of containers and empty holds for their cleanliness and suitability for sunflower 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 sunflower.

During loading, the inspector controls the loading of sunflower, confirms the gross / net weight during re-weighing; in the case of loading sunflower 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 FOSFA 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 sunflower quality.

We check the quality of sunflower exclusively in FOSFA accredited laboratories in accordance with the requirements of agreed per contract local or international standards. Usually for determination of sunflower quality the following standard parameters are used: color, smell, chemical composition of sunflower, acid number, moisture content, oil content, seed germination, protein content, oleic acid content, presence of impurities and pest infestation.

In addition to basic analyzes, laboratory tests are carried out for the presence of pesticides, mycotoxins, GMO, dioxins, heavy metals and radioactive elements in sunflower.

At the request of the client, during the loading process we also carry out express analyzes for each pre determined lot.

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 sunflower inspection, CISS GROUP provides a detailed photo report of all stages of control and inspection.


Based on the results of the sunflower 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.
