Scrap 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 scrap export/import operations is issued and received.
CISS GROUP provides scrap 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 scrap inspection is mainly due to an uniform composition of the scrap. Composition of the scrap determines the class of the cargo. Further difficulties of scrap metal inspection is due to possible radiation of the cargo as well as inclusion of explosive pieces. Therefore proper control of radiation and explosion safety is required. In this case, the background radiation and density are the determining indicators of the quality of scrap metal. The density index should be in the range of 0.8-1.3 t / m3, and the background radiation level should not exceed 0.02 μR / h.
Accredited inspectors and laboratory technicians from CISS GROUP carry out scrap inspection at any point of the supply chain.
The main stages of scrap inspection:
Incoming/outgoing scrap inspection.
It is carried out during the procurement, delivery of the cargo 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; will check scrap metal for compliance with the required class of the metal, inspect it for the presence of contamination, oiliness, corrosion, the presence of foreign non-metallic objects, non-ferrous metals in the scrap of ferrous metals, explosive substances and their residues; measure the background radiation; will check the weight of the incoming or unloaded cargo, take samples.
Acceptance of cleanliness containers / holds of vessels before loading scrap.
This is a visual inspection of containers and empty holds for their cleanliness and suitability for scrap 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 scrap.
During loading, the inspector controls the loading of scrap, confirms the gross / net weight during re-weighing; in the case of loading scrap 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 scrap quality.
We check the quality of scrap exclusively in accredited laboratories in accordance with the requirements of agreed per contract international standards.
Compliance of a lot of scrap metal with the requirements of contract specifications is determined visually. If the evaluation results are in doubt, then the batch can be checked using technical means (as cargo separation for example) and measuring equipment - though such determination is difficult and financially expensive, therefore the experience of attending inspector is of paramount importance.
The weight and dimensions of lumpy scrap metal are controlled by weighing and measuring.
To check scrap metal for contamination, size, weight, density, composition of alloyed components (impurities), at least five samples are usually taken.
To determine the presence of alloyed and non-ferrous metals or lump steel and cast iron scrap and waste in the proper scrap metal, the selected pieces are checked with a hand magnet, on a steeloscope or using other instruments and control methods.
The actual contamination of lump scrap metal with harmless impurities is determined by weighing the sample, cleaning it from non-metallic impurities using a tumbling drum or three times dropping from a height of two meters onto a concrete platform and re-weighing.
The contamination of steel or cast iron shavings with harmless impurities, oil and other harmful impurities is determined by washing the sampled sample with technical detergents, drying the separation from non-magnetic impurities, and weighing the shavings.
The contamination of cold-pressed bags and briquettes with harmless and harmful impurities is taken equal to the content of these impurities in the input raw materials for bags and briquettes.
The content of steel shavings in the bags is controlled during their manufacture by weighing, as well as by breaking/opening five control bags or briquettes and visual inspection of the content.
The density of packages and briquettes is determined by the ratio of their mass to volume.
The chemical composition of alloyed scrap metal is determined in accordance with regulatory documents or other methods that are not inferior to the standardized requirement
Rapid analysis of the chemical composition of scrap metal is carried out using X-ray spectrometers and analyzers, photovoltaic installations, etc., providing a measurement error specified in standards or other regulatory documents on analysis methods for the corresponding ranges of the mass fraction of elements.
If unsatisfactory test results are obtained for at least one of the indicators, a repeated test is carried out on it on a doubled number of samples taken from the same batch. Retest results apply to the entire batch.
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 scrap inspection, CISS GROUP provides a detailed photo report of all stages of control and inspection.
Based on the results of the scrap 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.Send request
