Potassium carbonate (potash) inspection is a critical quality control process conducted at various 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 professional potash inspection services to major agribusinesses and international trading companies at intermediate storage warehouses, elevators, factories, and ports worldwide.

Potash is classified as a fire and explosion hazard and belongs to the 3rd hazard class due to its potential impact on human health. Safe handling requires protective clothing, including a protective suit, mask, oil-resistant gloves, and specialized footwear. Potassium carbonate must be stored in closed, dry environments to prevent moisture absorption, as it is highly hygroscopic. As a chlorine-free fertilizer, potash is widely used in greenhouse vegetable production, promoting environmentally friendly cultivation. It can be transported in sealed containers using any covered vehicle, ensuring safe delivery to end users.

CISS GROUP’s accredited inspectors and laboratory technicians perform potash inspections at all supply chain stages.

The main stages of potash inspection:

Incoming and outgoing potash inspection

Inspection is conducted during potash delivery to silos, ports, or upon dispatch from factory or warehouse storage. The CISS GROUP inspector assesses storage conditions, ensuring cargo remains dry, uncontaminated, and free from pests, mold, foreign odors, or impurities. If potash is delivered in bags, the inspector checks for signs of moisture damage and, if required, opens selected bags for sampling and further quality assessment.

Container and vessel hold cleanliness inspection before loading

A thorough visual inspection ensures containers and vessel holds are clean and suitable for potash transportation. Inspectors check internal surfaces, door integrity, locks, hinges, rubber seals, and fasteners to confirm their condition before loading begins.

Loading supervision and potash sampling

During the loading process, the inspector oversees the operation, verifies gross and net weight through re-weighing, and, if applicable, performs draft surveys for bulk shipments. The fumigation process is monitored as needed. Potash samples are collected per 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 potash quality

Quality testing is performed in accredited laboratories following international standards and national methodologies (ISO, CEN, TFI – The Fertilizer Institute). Key quality parameters analyzed include:

• Appearance
• Potassium carbonate content
• Sodium carbonate content
• Potassium hydroxide content
• Iron content
• Heavy metal content
• Water-insoluble residue

Photo and video documentation

Each stage of the inspection is recorded with time-stamped photos and videos. At the end of the inspection, CISS GROUP provides a comprehensive photo report documenting all control and verification processes.

Certification and documentation

Upon completion of the inspection, a final certificate or detailed inspection report is issued. Clients can verify the authenticity of documents via a unique QR code, which grants access to the CISS GROUP website, where PDF versions of certificates are securely stored. Our certificates are digitally signed with cryptographic protection, ensuring their integrity and security.

Digitally signed certificates are often required by financial institutions when processing trade finance transactions, such as letters of credit, to validate compliance and trade integrity.
