Sulphur fertilizer inspection
Sulphur fertilizer inspection is an essential quality control process conducted at different stages of the logistics chain. It minimizes trade risks by ensuring that cargo meets agreed specifications, is delivered in the correct quantity, and includes all required documentation for export and import operations.
CISS GROUP provides sulphur fertilizer inspection services to leading agribusinesses and international trading companies at intermediate storage warehouses, elevators, factories, and ports worldwide.
Sulphur fertilizer inspection requires strict compliance with regulations for storage, transportation, and transshipment to maintain product properties such as friability and uniformity, which directly impact application efficiency. Sulphur fertilizers contain sulfur (S) in various chemical compounds. They are stored in bulk or packaged forms, with packaged and unpackaged fertilizers kept separately. Bulk fertilizers are stored in designated compartments or separated by portable barriers, and each type of fertilizer is labeled with its type, active substance content, and batch weight.
CISS GROUP’s accredited inspectors and laboratory technicians conduct sulphur fertilizer inspections throughout the supply chain.
The main stages of sulphur fertilizer inspection:
Incoming and outgoing sulphur fertilizer inspection
Inspection occurs during the delivery of sulphur fertilizer to silos, ports, or upon release from factories or warehouse storage. CISS GROUP inspectors evaluate storage conditions to ensure suitability for cargo storage. The cargo is checked to confirm it is dry, uncontaminated, free from pests, mold, foreign matter, and odors. If delivered in bags, inspectors assess packaging for moisture damage and, if required, open selected bags for sampling and further visual inspection.
Container and vessel hold cleanliness inspection before loading
A thorough visual inspection ensures that containers and vessel holds are clean and suitable for sulphur fertilizer transportation. Inspectors examine internal surfaces, verify the integrity of locks, hinges, rubber seals, and other fasteners, ensuring compliance with transport requirements.
Loading supervision and sulphur fertilizer sampling
During loading, inspectors oversee operations, verify gross and net weight through re-weighing, and, if applicable, conduct draft surveys for bulk shipments. The fumigation process is monitored as needed. Sulphur fertilizer samples are collected in accordance with international sampling standards, and composite samples are prepared. After loading, containers or holds are securely sealed. All data is recorded in detailed reports, which clients can access in real time. CISS GROUP provides 24/7 loading inspection and sampling services.
Laboratory analysis of sulphur fertilizer quality
Quality testing is conducted in accredited laboratories in compliance with international standards and national methodologies (ISO, CEN, TFI – The Fertilizer Institute). Standard quality parameters analyzed include:
- Appearance
- Mass fraction of nutrients
- Mass fraction of impurities
- Degree of polymerization
- Solution pH
- Particle size distribution
- Bulk density
- Strength of granules
- Crystallization temperature
- Friability
Photo and video documentation
Each stage of the inspection is recorded with time-stamped photos and videos. A comprehensive photo report is provided upon completion, documenting all inspection and control stages.
Certification and documentation
Upon completion of the inspection, a final certificate or detailed report is issued. Clients can verify document authenticity using a unique QR code, providing direct access to the CISS GROUP website where PDF versions of certificates are securely stored. Our certificates are digitally signed with cryptographic protection, ensuring document integrity and security.
Digitally signed certificates are often required by financial institutions when processing trade finance transactions, such as letters of credit, to verify compliance and trade integrity.
