ISO certification in Zambia signifies a company's commitment to quality standards and management systems. To achieve certification, companies undergo independent audits to ensure their business processes meet appropriate standards over time. This provides customers assurance that certified companies deliver quality products and services. Constant improvement is essential, as certification does not guarantee the best products - rather, it indicates a company makes efforts to produce good products consistently through adhering to ISO processes and refining practices. The main ISO standards implemented in Zambia include ISO 9001 for quality management, ISO 14001 for environmental management, ISO 45001 for occupational health and safety, ISO 27001 for information security, and ISO 22000 for food safety.
