Why Do Certifications Matter?
For an industrial buyer, purchasing coal from an ISO-certified supplier is not a secondary detail: it is a fundamental guarantee that the product will meet the promised specifications and that the supplier operates within the legal framework.
Consistency
Uniform quality guarantee lot to lot, backed by independent audits.
Customs
Friction-free acceptance at international customs thanks to ISO accreditation.
Audits
Compliance with supplier audit requirements from major industrial buyers.
Traceability
Full lot traceability for sustainability and supply chain reporting.
Support
Support for the client's own certifications before their own auditors.
Risk
Reduced operational risk: a response system exists for any incident.
Certification and Renewal Process
Maintaining an ISO certification requires a continuous, not one-off, commitment.
Internal Audits
We carry out semi-annual internal audits led by certified internal auditors who verify compliance with all management system requirements.
External Audits
Annually, the certifying body carries out a surveillance audit. Every three years, a full certificate renewal audit is carried out, including review of all processes.
Management Review
Senior management annually reviews the performance of the management system, audit results, quality indicators and objectives for the next period.
