EU Drinking Water Directive
Products that come into contact with water sell extremely well in e-commerce. Shower heads, plumbed-in water filters, faucets, or accessories for boilers and drinking water systems are among the classics on Amazon and in online shops. However, what many sellers underestimate is this: As soon as a water supply system or another installation used for the provision of drinking water comes into contact with that drinking water, a particularly strict regulatory framework applies.
With the EU Drinking Water Directive (EU) 2020/2184, the European Union is tightening the requirements precisely in this area, and quite significantly. For you as an online seller, this means: product safety does not end with CE marking or GPSR, but goes much further for drinking water products.
This blog post tells you:
- why the EU Drinking Water Directive is relevant for you
- which products are affected
- which new requirements you need to prepare for
- and how to position yourself correctly as a seller now in order to avoid suspensions, fines, and recalls
Why the EU Drinking Water Directive is relevant for online sellers
In the EU, drinking water is considered an especially protected good. Anything that comes into contact with drinking water can potentially release substances that are harmful to health. That is exactly why materials that come into contact with drinking water are increasingly becoming the focus of legislators, authorities, and platforms.
This is especially relevant for e-commerce because many products may seem small and inconspicuous, but are highly sensitive from a regulatory perspective. Typical examples in e-commerce include:
- shower heads and hand showers
- kitchen and bathroom faucets
- water filters and filter cartridges, if plumbed in
- hoses, seals, and valves
- accessories for boilers, tankless water heaters, or drinking water systems
If you sell such products, whether as private label products, imported goods, or trading goods, the EU Drinking Water Directive affects you directly.
Background and objectives of the EU Drinking Water Directive
The current EU Drinking Water Directive (EU) 2020/2184 was adopted in order to improve consumer health protection and create harmonized standards across Europe. It replaces the previous directive and responds to new scientific findings, for example on harmful substances such as PFAS or heavy metals.
The main objectives of the directive are:
- protection of human health
- reduction of contaminant input from materials
- harmonization of requirements across all EU Member States
- greater transparency and control throughout the supply chain
The directive has already entered into force, and implementation is taking place step by step through national rules. Particularly important for sellers: many requirements will be checked on a binding basis from 2026 onward.
Which products are affected?
The EU Drinking Water Directive applies to all materials and products that come into permanent or regular contact with drinking water. It does not matter whether the product actively carries water or is “only” installed within the flow path.
In e-commerce, the following product groups are among those that are relevant:
- sanitary products, such as faucets, showers, and valves
- kitchen products with a water connection
- water filters and filter housings
- spare parts such as hoses, seals, and cartridges
- accessories for drinking water installations
Important for you: spare parts and accessories are also covered by the rules if they come into contact with drinking water. In practice, this is often overlooked, with the corresponding risks.
New material requirements: What is changing now
A key component of the EU Drinking Water Directive is the introduction of EU-wide positive lists for materials that may come into contact with drinking water. These positive lists will become binding from 2026 onward. In practical terms, this means that only materials included on these lists and complying with the specified limits may be used in the future.
The following points are especially relevant:
- limit values for heavy metals such as lead and nickel
- new and stricter rules for PFAS
- migration-based testing for plastics and metals
Transition periods are intended to facilitate harmonization. Nevertheless, the pressure to test and provide evidence is already increasing. In addition, national guidance, such as the UBA guidelines in Germany, continues to play an important role, although only on a transitional basis.
How the Food Contact Materials Regulation, the LFGB, and the Drinking Water Directive differ
Many sellers assume that food contact materials and drinking water products are regulated in a similar way. In practice, however, there are clear differences that you absolutely need to know.
The EU Food Contact Materials Regulation and the German Food and Feed Code deal with materials that come into contact with food or food surfaces. The key question here is whether substances from the material can migrate into the food. Typical product examples include:
- kitchen utensils, such as spatulas, whisks, or rolling pins
- packaging, such as cling film or aluminum foil
- coated surfaces that come into contact with food, such as non-stick coatings on pans
The EU Drinking Water Directive, by contrast, deals with installations that come into contact with drinking water. Separate positive lists, stricter limit values, and specific migration tests apply here.
One key misunderstanding is this: food-safe does not automatically mean suitable for drinking water. Both regulatory areas pursue the same goal, namely the protection of human health, but they require completely different test methods, limit values, and evidence.
If you offer products from both categories, you should consider the respective requirements separately in order to avoid risks such as recalls, platform suspensions, or inquiries from authorities.
Your obligations as an e-commerce seller
As soon as you distribute products that come into contact with drinking water, you have clear obligations. You must ensure that your products comply with the requirements and that you are able to prove this.
There are three central areas.
1. Drinking water certificates
2. Laboratory tests
In addition to certificates, migration tests are crucial. These tests examine whether, and which, substances can migrate from the material into the water. Relevant substances include:
- metals, such as lead and nickel
- plastics
- PFAS and other harmful substances
3. Documentation
All evidence must be available in a structured format and often also in the national language, especially in the case of platform requests or checks by authorities.
Delimitation from the German Drinking Water Ordinance
A common misconception is that many sellers confuse the EU Drinking Water Directive with the German Drinking Water Ordinance.
The distinction is important for you:
- the German Drinking Water Ordinance primarily regulates the quality of the water that reaches the consumer, meaning the obligations of water suppliers
- the EU Drinking Water Directive focuses on materials and products that come into contact with drinking water
For you as a seller, this means: your focus is on product conformity, not on water quality in the household.
Risks of non-compliance
If you ignore or underestimate the requirements, the consequences can be significant. In practice, we are increasingly seeing:
- suspension of listings on Amazon and other platforms
- sales stops for entire product groups
- fines and liability risks
- expensive recalls
- lasting reputational damage
Especially in e-commerce, such measures immediately affect revenue and visibility.
Recommended actions for sellers
In order to minimize risks, you should take action at an early stage. The following steps have proven particularly effective:
- close coordination with manufacturers and suppliers
- checking the materials used for compliance with the positive lists
- early laboratory testing for new products
- establishment of clean, structured compliance documentation
- use of EU-recognized testing bodies
The earlier you address these points, the more calmly you will be able to respond to future checks.
Outlook: What sellers should expect
The direction is clear: the requirements will continue to increase. Topics such as stricter PFAS limits, possible microplastics monitoring, and integration with the Digital Product Passport will make drinking water compliance even stricter.
Sellers who act proactively now will gain a real competitive advantage and avoid rushed adjustments under time pressure.
Conclusion: Drinking water compliance is no longer a side issue
If you sell products that come into contact with water, the EU Drinking Water Directive is not a “special case” for you, but a requirement. Those who proceed in a structured way at an early stage reduce risks, strengthen their market position, and remain capable of acting in the long term.
