BQCIS

Comprehensive Analysis for Quality Assurance and Compliance

BQCIS coal laboratories operate under ISO/IEC 17025 accreditation and follow internationally recognized methods such as ASTM, ISO, and GB/T. We support both producers and end users by providing fast, accurate testing across the full quality spectrum — from calorific value to trace element profiling.

Our network of advanced analytical laboratories delivers consistent and defensible results for global trade documentation, contract validation, and quality certification. We ensure that every analytical result reflects true coal performance characteristics, helping clients minimize risk and improve blending or utilization decisions.

From mine site sample testing to vessel shipment certification, BQCIS delivers dependable data that forms the backbone of technical assurance in the coal supply chain.

Key Laboratory Analysis Activities

Proximate, Ultimate & Calorific Testing

Determination of moisture, ash, volatile matter, and fixed carbon under ASTM D3172 and ISO 17246. Calorific value measured using bomb calorimetry provides precise energy yield. These core analyses form the foundation for commercial valuation and blending optimization.

Ash Fusion & Trace Element Analysis

Determination of ash softening, hemispherical, and fluid temperatures in reducing and oxidizing conditions under ASTM D1857. Trace element detection via ICP-MS quantifies mercury, arsenic, and other critical metals, supporting emissions control and regulatory compliance.

Success Story

Accredited Testing Resolves Contract Dispute

The Challenge:

A buyer contested the calorific value results from a supplier’s in-house lab, delaying payment and shipment release.

Our Solution:

BQCIS independently collected sealed umpire samples and performed full proximate, ultimate, and calorific testing under ISO/IEC 17025 accreditation. The results were within 0.3% reproducibility and verified by both parties.

The Result:

The certified BQCIS report served as binding reference, resolving the dispute and restoring confidence between the buyer and supplier for future transactions.
