Omniseal Solutions, a global leader in precision sealing and wear and friction control solutions for over 65 years, announces that its Kontich site has been certified to ISO 19443:2018 for Important To Nuclear Safety (ITNS) activities, which covers the design and manufacture of high-performance seals, bearings, wear technology and specialty products, as well as technical advice in sealing technology. Since June 12, 2026, the Kontich management system is covered by SGS certificate FR26/00000078, demonstrating internationally recognized quality-management requirements for organizations supplying products and services important in nuclear safety.

ISO 19443 builds upon ISO 9001:2015 by adding nuclear-sector requirements for organizations supplying products or services critical to nuclear safety. This specialized standard strengthens areas such as nuclear safety culture, risk-based decision-making, traceability, supplier oversight and the prevention of counterfeit, fraudulent and suspect items.
For nuclear developers, equipment manufacturers and supply-chain partners, the certification provides competitive advantages and independent assurance that the Kontich site adheres to strict quality-management standards specifically designed for ITNS operations. This milestone builds on early-stage engagement on demanding sealing applications, establishing the rigorous controls required to scale from development and prototype activities toward qualified, repeatable production.
How does the ISO 19443 certification impact Omniseal Solutions and its role in the nuclear industry?
- Ensures systems, processes, and culture are aligned with internationally recognized nuclear requirements
- Provides customers with an internationally recognized nuclear quality-management baseline, helping streamline supplier assessment while complementing applicable customer, regulatory and national quality requirements (fragmented, country-specific quality assurance frameworks: NQA-1 in the US, CSA N299 in Canada, and RCC-M in France)4
- Strengthens customer confidence in the Kontich site's ability to manage qualifying sealing and engineered-product activities within the certified ITNS scope
- Positions their Kontich site as a trusted partner for safety-related applications
Due to a global resurgence in the nuclear industry, new reactor projects such as Small Modular Reactors (SMRs), advanced reactor technologies, fusion initiatives, medical isotope production, spent fuel management, and plant life extensions are driving renewed demand for qualified suppliers. Customers expect suppliers to demonstrate technical excellence and proven results as well as an agile nuclear-specific quality culture and robust supply chain controls. Since the scope of the ISO 19443 standard extends from large power station operators to small-scale subcontractors at the very end of the supply chain, this certification is beneficial to a vast network of global suppliers providing the thousands of components, services and engineering support required to ensure quality and safety in this growing sector. Therefore, Omniseal Solutions considers this achievement much more than a quality certification; it represents a strategic investment in the future of the company's presence in the global nuclear industry.
"Our EN 9100-certified quality system gave us a strong foundation; however, ISO 19443 required us to integrate nuclear safety culture, supplier oversight and nuclear-specific risk management more deeply into our daily operations," said Toon Wauters, Quality Manager and ISO 19443 Project Lead. "The real achievement is not only the certificate. It is the collaboration, discipline and mindset built across the Kontich organization, which will continue to benefit our customers long after the audit."
"Nuclear customers need more than a technically capable seal supplier. They need confidence that design, manufacturing, traceability and supply-chain controls are managed with the discipline required for safety-related applications. ISO 19443 gives us a stronger platform to support customers from early development through industrialization," said Dimitri Van den Broeck, Omniseal Solutions' Business Manager Nuclear and ISO 19443 Project Sponsor.
Moving forward, Omniseal Solutions can strategically and functionally support global customers who operate in some of the world's most demanding environments: extreme radiation, pressures, temperatures, and coolant conditions, which require specialized sealing materials and designs. By delivering customized sealing solutions, their customers will benefit significantly as they move toward commercialization, linking future opportunities in next-generation nuclear technologies to nuclear compliance capabilities as well as strengthening competitiveness.
Omniseal Solutions' future priorities include continuous improvement of the certified management system, further development of the nuclear safety culture, expansion of products supported under nuclear quality requirements, and continued alignment of our US operations with applicable NQA-1 customer expectations.
