Key takeaway
What This Development Means
Czechia's proposal would align drinking water contact materials with EU positive lists, testing, conformity assessment and marking. Manufacturers and importers should map formulations, certificates, laboratories and supplier changes, while water-treatment businesses assess chemicals, filter media and equipment. Existing compliant products may benefit from transition until the end of 2032 nationally.
Which products fall within the Czech proposal?
Drinking water contact materials include products that touch potable water, alongside treatment chemicals and mixtures, filter media, treatment technologies and point-of-use or distribution equipment that can affect quality. Pipes, fittings, seals, coatings, membranes, filters and dosing systems may require different evidence, testing or conformity-assessment routes under the proposed Czech framework.
Can existing certificates continue to be used?
The notification says products and materials with valid certificates under legislation, plus compliant treatment media, technologies and equipment, may continue to be marketed and used until the end of 2032. Businesses should verify the transitional text and plan recertification by product family, because formulation or supplier changes could affect eligibility.
Source basis: European Commission Technical Regulation Information System, Czech draft public-health law received 21 July 2026
Czechia has notified a draft public-health law that would align drinking water contact materials with the EU's harmonised hygiene framework. Received by the European Commission on 21 July 2026, the proposal reaches beyond pipe manufacturers to coatings, seals, membranes, filters, treatment chemicals, equipment suppliers, importers, laboratories, utilities and construction businesses. The TRIS standstill ends on 22 October 2026.
One System For Substances, Testing And Marking
The draft would connect Czech enforcement with EU measures adopted under the Drinking Water Directive. Those measures establish European positive lists for starting substances, compositions and constituents, methods for testing final materials, conformity-assessment procedures and harmonised product marking.
For drinking water contact materials, the practical question is no longer simply whether a finished component passes a familiar national test. Manufacturers need traceable evidence linking formulation, approved inputs, migration performance, certification and marking. A resin substitution, coating change or new supplier could alter several parts of that file at once.
The Czech Ministry of Health would designate and oversee conformity-assessment bodies. Regional public-health authorities would continue supervising products and materials on the market.
Water-Treatment Products Also Enter The Compliance Picture
The proposal covers chemicals, mixtures and filter media used directly in water, alongside treatment technologies and equipment that can affect quality. The official notification highlights risks including substance migration, microbial growth and unwanted changes to water's physical or chemical properties.
Existing compliant products, technologies and equipment, plus materials holding valid certificates under current rules, could continue to be marketed and used until the end of 2032. That runway is useful, but product families with long certification cycles should not wait for the final year.
Build A Product-Family Evidence Map
Suppliers should group drinking water contact materials by composition and use, identify certificates that rely on current Czech rules, and ask laboratories how EU methods will change testing plans. Importers and distributors should secure declarations, marking information and change-notification commitments from manufacturers before specifications are renewed.

EPA PFAS Drinking Water Rule Faces Revision, Raising Compliance Uncertainty
The EPA PFAS drinking water rule is not being withdrawn, but parts of it are being revised. Limits for PFOA and PFOS remain central, while compliance timing and standards for other PFAS may change. Businesses should treat this as a compliance uncertainty issue, not a pause in PFAS regulation.
