Cargo weight & quality determination

Cargo weight stays verified and traceable from loading through discharge, keeping supply chain risk management under control. Weight and quality determination minimises discrepancies between loading and unloading figures, giving bulk cargo stakeholders certainty, risk control and demonstrable quality at every transfer point.

    Quality and compliance in weight determination

    Control Union holds an independent position in the supply chain, secured through accreditations that make accredited marine surveyors the foundation of every weight and quality check. This independence structurally combines with logistics coordination and laboratory analyses, delivering integrated proof that single-discipline providers cannot replicate.
    Organisations gain a credible, auditable record that links field inspection results directly to lab-verified quality data, reducing disputes and strengthening contractual positions.

    How we work

    Towards control, insight, and certainty

    The strength lies in the combination of inspection expertise, advanced data systems, and global practical experience.

    Transfer survey

    Qualified surveyors supervise loading and discharge operations in the port, confirming cargo condition and initial weight at the point of transfer.

    Quantity measurement

    Measurement execution covers vessel draft survey, gauging, tank measurements, tallying and volumetric determination of stockpiles to establish accurate cargo quantities.

    Final verification

    Surveyors check calibrated weighing scales and terminal figures, verifying final outcomes against contractual specifications before issuing results.
