Coal and coke inspection ensures quality control at various stages of the logistics chain, minimizing trade risks associated with non-compliance with agreed specifications, quantity discrepancies, or missing documentation in export/import operations.

CISS GROUP provides coal and coke inspection services to major metallurgical holdings, processing plants, scrap steel suppliers, and international metal trading companies during procurement, storage, and loading/unloading at intermediate warehouses and ports worldwide.

Coal and coke inspection ensures compliance with relevant standards, regulatory requirements, and commercial terms while assessing the environmental and safety impact of the cargo. Accredited inspectors and laboratory technicians from CISS GROUP conduct inspections at any stage of the supply chain.

The main stages of coal and coke inspection:

Incoming/outgoing coal and coke inspection

Conducted during procurement, delivery to warehouses or ports, and removal from storage facilities. CISS GROUP inspectors visually assess storage conditions, inspect for potential losses (theft or spills), verify compliance with classification criteria (size, fines content, and mineral impurities), control weight, and perform sampling.

Container and vessel hold cleanliness inspection

A visual assessment of containers and vessel holds before loading ensures cleanliness and suitability for transportation. Inspectors check internal surfaces, lock integrity, hinges, fasteners, rubber seals on container doors, and hold covers.

Loading process control and sampling

During loading, inspectors oversee coal and coke handling, confirm gross and net weight through re-weighing, and conduct draft surveys for weight verification. They monitor fumigation, perform visual quality assessments, and collect samples following international standards. Once loading is complete, inspectors seal containers or holds and compile reports accessible to clients. CISS GROUP offers 24/7 loading inspection and sampling services.

Laboratory analysis of coal and coke quality

Quality testing is performed exclusively in accredited laboratories in compliance with international contract standards. Laboratory analyses assess chemical, physical, and mechanical properties, as well as combustion characteristics.

• Chemical Properties: Moisture, ash content, volatile matter, fixed carbon, and sulfur content.
• Moisture Content: Determined through direct and indirect methods, influencing fuel properties.
• Ash Content: Evaluated by ashing the sample at 815 ± 10°C until a constant weight is achieved.
• Sulfur Analysis: Determines sulfur oxide emissions during combustion.
• Fixed Carbon Content: Calculated by subtracting moisture, volatiles, and ash from the sample weight to estimate coke yield.
• Physical and Mechanical Properties: Specific gravity, particle size distribution, float tests, and wear resistance (abrasion).
• Combustion Tests: Include specific energy determination, ash melting tests, and crucible swelling index analysis.

Photo and video documentation

Each inspection stage is recorded through photos and videos with timestamps. Upon completion, CISS GROUP provides a comprehensive photo report covering all inspection phases.

Certification

Final certificates and reports are issued based on inspection results. Clients can verify document authenticity via a unique QR code linking to the CISS GROUP website, where secure PDF versions are stored. Digital cryptographic signatures enhance document security and authenticity.

Digitally signed certificates are widely accepted by banks for trade finance verification, ensuring the integrity of trading transactions and supporting letter-of-credit operations.

With a commitment to quality and compliance, CISS GROUP delivers industry-leading coal and coke inspection services, safeguarding client interests and ensuring trade reliability in global markets.
