Non Intentionally Added Substances | NIAS Testing
We provide NIAS testing and risk assessments to evaluate the hazard of the identified substances as included in Regulation EU 10/2011.
Understanding NIAS and Purity Regulations in Food Contact Materials
Helping you navigate evolving NIAS requirements, analytical challenges and risk assessment with confidence
As regulatory scrutiny and analytical capabilities continue to evolve, greater focus is being placed on better understanding and assessing Non-Intentionally Added Substances (NIAS) in food contact materials, particularly those present at low levels and exhibiting non-volatile behaviour.At the same time, regulatory developments such as Commission Regulation (EU) 2025/351 are placing greater emphasis on purity requirements, impurities, and non-listed substances within food contact materials, increasing the complexity of compliance and risk assessment activities.
This expert article from Smithers’ food contact specialists provides a clear overview of the key scientific and regulatory considerations associated with low-level non-volatile NIAS, alongside practical insight into how these challenges can be addressed through advanced analytical and risk assessment strategies.
What you’ll learn:
- What NIAS are and why low-level non-volatile substances are receiving increased attention
- How evolving EU purity requirements are influencing NIAS assessment strategies
- Why advances in analytical sensitivity are creating new interpretation and risk assessment challenges
- How migration testing and non-targeted analysis support NIAS assessment
- The practical challenges of assessing unknown substances and working with limited toxicological data
- Why proportionate, risk-based decision-making is critical in NIAS assessment
Understanding NIAS is only part of the challenge. Turning analytical findings into proportionate, defensible compliance decisions requires both advanced testing and regulatory expertise. Smithers supports organisations through non-targeted screening, migration testing, risk assessment and food contact regulatory guidance.
