Verification of compliance

Without independent verification of compliance, you can never know if the criteria are met. To test and audit products and their manufacturing facilities, extensive resources and technical expertise are needed. For credible results, it is also important that the verifiers have no affiliation with industry, purchasers or any other interest group that could influence the test results. This is why compliance with all criteria in TCO Certified is verified by independent and accredited verification organizations, in accordance with ISO/IEC 17025.

With TCO Certified, compliance with all criteria is independently verified by accredited experts. They spend more than 20,000 hours on product testing and supply chain assessments each year. Verification is mandatory and continuous — it is carried out both before and after certification, throughout the certificate’s validity period.

However, finding sustainability issues is only the first step on the way to more sustainable practices. We ensure progress by holding the industry accountable for also solving the issues. TCO Certified includes a structured system for continuous improvements and guides the industry to more sustainable ways of working. Corrective action plans must be developed and implemented within a set timeframe. Non-compliance is met with real consequences — certificates can be removed and factories may lose the right to manufacture certified products.
