Slabs 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 slabs export/import operations is issued and received.

CISS GROUP provides slabs inspection services to large metallurgical holdings, processing plants, slabs 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 slabs inspection is due to the requirement of careful control of entire loading process of the cargo. In particular, when loading onto ships, slabs of each tier must be stacked on wooden dunnage of a certain thickness. Dunnage for the first tier should be laid in the plane transversely to the loaded cargo. Inter-tier transverse dunnage pieces should be located at a certain distance from each other horizontally and strictly one above the other vertically. Compliance with the requirements for the laying of slabs in the holds - and proper lashing of the load - ensures the stability of the cargo during transportation and, accordingly, safe navigation.

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

The main stages of slabs inspection:

Incoming/outgoing slabs inspection.

It is carried out during the procurement, delivery of fittings to warehouses or to the port, or during removal from the warehouses of metallurgical enterprises.

The CISS GROUP inspector will visually assess the condition of the premises for the suitability for cargo storage; check the availability of accompanying documentation for each batch; inspect the surface of slabs for damages and defects, check the depth of defects, measure the width, thickness, other geometric dimensions and shape of slabs, take samples.

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

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

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

We check the quality of slabs exclusively in accredited laboratories in accordance with the requirements of agreed per contract international standards.

The chemical composition of slabs is determined on one slab from a batch, in accordance with the current regulatory documents, which ensure the required analysis accuracy.

The depth of the defects is determined by lightening or trial cleaning.

The width of the slabs is measured at a distance of at least 200 mm from the ends, and the thickness at a distance of 200 mm from the ends and 40 mm from the side edges. The thickness of slabs stacked on slabs may be measured at a distance of 100 mm from the side edges.

The geometric dimensions and shape of the slabs are checked using squares and measuring tools with an error of not more than 1.0 mm

The weight of the sample is determined by dimensional calculation multiplied by the density of the metal supplied by the producer or checked in the laboratory.

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


Based on the results of the slabs 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.
