Send request

Iron ore and concentrate 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 iron ore and concentrate export/import operations is issued and received.

CISS GROUP provides iron ore and concentrate inspection services to large metallurgical holdings, processing plants, scrap steel purveyors and international metal trading companies during procurement, storage, as well as loading / unloading at intermediate warehouses or in ports around the world.

The distinctiveness of iron ore and concentrate inspection is due to rigid transportation requirements of such goods. Due to high value of these goods its transportation represents high commercial risks for all parties to the transaction. Therefore, weight control, sampling and laboratory quality testing in accordance with standards is very important during handling.

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

The main stages of iron ore and concentrate inspection:

Incoming/outgoing iron ore and concentrate inspection.

It is carried out during the procurement, delivery of iron ore and iron ore concentrate to warehouses or to the port, or during removal from the warehouses.

The CISS GROUP inspector will visually assess the condition of the premises for the suitability for product storage; will check the weight of the incoming / unloaded cargo and take samples. Before sampling, the inspector will inspect the consignment for a visual determination of its uniformity in size and moisture content of the material.

Acceptance of cleanliness containers / holds of vessels before loading iron ore and concentrate.

This is a visual inspection of containers and empty holds for their cleanliness and suitability for iron ore and concentrate 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 iron ore and concentrate.

During loading, the inspector controls the loading of iron ore and concentrate, confirms the gross / net weight during re-weighing; in the case of loading iron ore and concentrate 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 iron ore and concentrate quality.

We check the quality of iron ore and concentrate exclusively in accredited laboratories in accordance with the requirements of agreed per contract international standards.

Quality indicators include mass fractions of total iron, iron oxide, metallic iron, moisture, hygroscopic moisture, arsenic, phosphorus, sulfur, copper, zinc and lead. Also determine the particle size distribution, the degree of uniformity in chemical and particle size distribution.

Other tests include immersion test, size distribution, cold compressive strength, abrasion index.

To determine the quality of minerals, a composite sample representing the entire lot of the cargo is used, while the determination of the mass fraction of total iron and moisture is carried out for each controlled batch.

Determination of the mineralogical type of iron ore and iron ore concentrate is based on measuring the quantitative ratios of iron ore minerals.

Studies include macroscopic and microscopic types of analysis.

Macroscopic analysis determines the mineral composition of the test sample, describes the macrostructure, color, luster, physical and mechanical properties (hardness, porosity), the nature of secondary changes (oxidation, leaching, cementation), tectonic disturbances, the presence of veins and veins.

Microscopic analysis determines the exact mineral composition, structural and genetic relationships of minerals, particle size distribution, shape of mineral grains, shape and size of inclusions in aggregates of ore minerals, characteristic features of minerals, structural changes, inclusions using a polarizing microscope. In addition, the quantitative ratios of minerals in the ore and their grain sizes are calculated.

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 iron ore and concentrate inspection, CISS GROUP provides a detailed photo report of all stages of control and inspection.


Based on the results of the iron ore and concentrate 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.
