Analysis of coal and minetal quality indicators – Standardization for global markets

Vietnam is endowed with abundant mineral resources, with hundreds of mines under active exploitation and substantial reserves of key minerals such as coal, titanium, white sand, rare earths, and other industrially significant raw materials. To ensure these valuable resources are efficiently utilized and integrated transparently and fairly into the global supply chain, inspection, verification, and quality analysis play a pivotal and indispensable role in every commercial transaction and logistics process.

VM CONTROL is proud to be a pioneering provider of coal and mineral inspection and analysis services in Vietnam. We partner with leading laboratories accredited to ISO/IEC 17025 standards to ensure all analytical results are accurate, reliable, and compliant with both local and international technical requirements.

1. Weight Determination Inspection

Accurate weight determination is fundamental in trade control and logistics operations. Depending on operational conditions, VM CONTROL applies various methods:

  • Draft survey for bulk cargoes on vessels or barges;

2. Quality (Grade) Inspection

A critical step to ensure the product complies with technical specifications outlined in commercial contracts or Letters of Credit (L/C). Typical quality parameters analyzed include:

  • Major and trace mineral content (SiO₂, Fe₂O₃, Al₂O₃, TiO₂, etc…);
  • Physicochemical properties such as moisture, ash, sulfur content, calorific value (for coal);
  • Particle size distribution, purity, hardness, water permeability;
  • Process-specific criteria for metallurgy, construction materials, and other industrial applications.

Sampling guidelines:

  • 1 composite sample per 500 MT for high-speed conveyor loading/unloading;
