Sodium sulfate 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 sodium sulfate export/import operations is issued and received.

CISS GROUP provides sodium sulfate inspection services to large agribusinesses and international trading companies in intermediate storage warehouses, elevators, factories or ports around the world.

The distinctiveness of sodium sulfate inspection is that its storage requires closed rooms, excluding the possibility of humidification and other contamination. Sodium sulfate is fire- and explosion-proof, and due to its effect on the human body belongs to the fourth hazard class. The shelf life of sodium sulfate is no more than six months from the date of manufacture. It is allowed to transport these products in packaged form (paper, plastic bags), as well as in disposable soft containers and closed railway wagons in bulk. When transporting loose bulk fertilizers, transportation units must be covered with a tarpaulin to prevent dust formation.

Accredited inspectors and laboratory technicians from CISS GROUP carry out sodium sulfate inspection at any point of the supply chain.

The main stages of sodium sulfate inspection:

Incoming/outgoing sodium sulfate inspection.

It is carried out during delivery of sodium sulfate to silos or to a port, or at releasing it from factory/silo warehouses. The CISS GROUP inspector will visually assess the condition of the premises for the suitability for cargo storage; will check the cargo itself so that it is dry, not mixed with other cargo, not damp or wet, free from pests, foreign matter, weeds, mold or foreign odors. If sodium sulfate is delivered in bags, the inspector will inspect them for traces of soaking, and if agreed, will perform the selected bag opening for sampling purpose and further visual check of cargo quality.

Acceptance of cleanliness containers / holds of vessels before loading sodium sulfate.

This is a visual inspection of containers and empty holds for their cleanliness and suitability for sodium sulfate 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 sodium sulfate.

During loading, the inspector controls the loading of sodium sulfate, confirms the gross / net weight during re-weighing; in the case of loading sodium sulfate 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 sodium sulfate quality.

We check the quality of sodium sulfate exclusively in accredited laboratories in accordance with international standards and national methods (ISO, CEN, TFI (The Fertilizer Institute)) and others. The determined standard indicators of the quality of sodium sulfate include: mass fraction of sodium sulfate, mass fraction of water-insoluble residue, mass fraction of chlorides in terms of sodium chloride, mass fraction of calcium sulfate, mass fraction of magnesium ions, mass fraction of iron, mass fraction of water, mass fraction the proportion of sodium nitrite and sodium nitrate, mass fraction of sodium carbonate.

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 sodium sulfate inspection, CISS GROUP provides a detailed photo report of all stages of control and inspection.

Certificates.

Based on the results of the sodium sulfate 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.
