Rare earth materials (zircon and rutile concentrates) inspection ensures quality control at different stages of the logistics chain, minimizing trade risks associated with specification deviations, discrepancies in quantity, or incomplete documentation for export and import operations.

CISS GROUP provides rare earth materials (zircon and rutile concentrates) inspection services for major metallurgical holdings, processing plants, scrap steel suppliers, and international metal trading companies. These services cover procurement, storage, loading, and unloading at intermediate warehouses and global ports.

Zirconium concentrate presents fire and explosion hazards and has a general toxic effect on the human body. Inspection must be conducted using personal protective equipment, including respirators, goggles, overalls, safety shoes, gloves, and hand protection.

Storage premises for these materials must be equipped with ventilation systems, which must remain operational throughout the inspection process.

Accredited inspectors and laboratory technicians from CISS GROUP conduct inspections at every stage of the supply chain.

Main stages of rare earth materials (zircon and rutile concentrates) inspection:

Incoming and outgoing inspection

This stage includes procurement, delivery to warehouses or ports, and removal from storage facilities. CISS GROUP inspectors assess storage conditions, verify the availability of quality certificates for each batch with actual parameter values, and conduct visual inspections for foreign inclusions, impurities, and packaging integrity. Labeling on containers is checked for compliance. Inspectors also verify cargo weight and take samples.

Container and vessel hold cleanliness inspection

A visual inspection of containers and empty holds ensures cleanliness and suitability for transportation. Inspectors examine internal surfaces, assess the integrity of locks, hinges, and fasteners, and check rubber seals on container doors and hold covers.

Loading process monitoring and sampling

During loading, inspectors oversee operations, confirm gross and net weight, and conduct weight checks using the draft survey method. They monitor the fumigation process, visually assess cargo quality, and collect samples according to established procedures. At the end of loading, inspectors seal containers or holds and document findings in real-time reports. CISS GROUP provides 24/7 inspection and sampling services.

Laboratory analysis of rare earth materials (zircon and rutile concentrates) quality

Quality testing is conducted exclusively in accredited laboratories following international contractual standards.

Tests of zirconium concentrate physical properties include hardness, bulk density, angle of repose, moisture content, melting point, flammability, water solubility, color, and mesh residue determination.

Chemical testing determines mass fractions of zirconium and hafnium oxides, iron oxides, titanium dioxide, aluminum oxide, water, and other elements.

Mineral composition analysis identifies percentages of zircon, rutile, quartz, and other components.

Rutile concentrate quality indicators include mass fractions of titanium dioxide, alumina, iron oxide, silicon dioxide, zirconium dioxide, phosphorus pentoxide, sulfur, moisture, and residue on the grid.

If test results do not meet contract specifications for any parameter, a retest is conducted using a new sample. Retest results apply to the entire batch.

Photo and video reporting

Each inspection stage is documented through photographs and videos, timestamped for accuracy. Upon completion, CISS GROUP provides a detailed photo report covering all inspection and control stages.

Certification

Following the inspection, final certificates or reports are issued. Clients can verify document authenticity via a unique QR code, granting access to digital certificates on the CISS GROUP website. Digital cryptographic signatures ensure security and reliability.

Digitally signed certificates are often required by banks for trade financing verification, particularly in letter-of-credit transactions.
