EU-MHR Pre-Assessment Services

Starting 1 January 2027, all products that come into contact with drinking water in the EU must meet strict health and safety standards under the new EU-MHR regulation. NSF is here to help you navigate this transition with confidence

The EU-MHR will replace existing national certification schemes—including France’s ACS and Germany’s UBA Guidelines—creating a single, unified regulatory framework across all EU member states.

Key changes include:

• Mandatory testing and certification for all products in contact with drinking water.
• Regular audits of production facilities.
• One harmonised standard for market access across the EU.

With 80+ years of global expertise in public health and product certification, NSF offers comprehensive pre-assessment services to guide you through the complexities of the EU Drinking Water Directive and the certification of your products and materials under the upcoming EU-MHR.

We support you at every stage—from formulation review to facility audits—ensuring your products are fully compliant before the deadline.

Below are the ways NSF can pre-assess your products and ingredients for EU-MHR readiness:

• Formulation technical review: Our regional experts analyse your product’s formulation and ingredients to ensure compatibility with EU-MHR standards.
• Testing under EU-MHR conditions: Our European lab in Rheda, Germany is equipped to perform all required tests under the EU Drinking Water Directive.
• Facility and quality system evaluation: We assess your production site, quality systems, and identify non-conformities. With auditors in 110+ countries, NSF makes global compliance seamless.
• Pre-product evaluation and certification: Using Protocol 534, we evaluate health effects of pre-products to confirm their safety for drinking water contact. Learn more about Protocol 534.
