Formaldehyde under REACH: Regulatory background and current classification

From CLP classification to the amendment of Annex XVII – why the EU has reassessed formaldehyde and what this means for industry.

Inicio Insights Technologies

Formaldehyde has been a key component in numerous industrial applications for decades, but at the same time, this colourless gas is increasingly coming under regulatory scrutiny. With the amendment of Annex XVII of the REACH Regulation by Regulation (EU) 2023/1464, the European Union has introduced binding emission limits for a wide range of products for the first time.

To understand the scope of this regulation, it is worth taking a look at its regulatory background.

The legal starting point

REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) forms the central legal framework of the EU for the handling of chemical substances. The aim is to ensure a high level of protection for humans and the environment while at the same time guaranteeing the free movement of goods within the internal market.

Regulation (EU) 2023/1464 of 14 July 2023 extended Annex XVII of the REACH Regulation. This means that, for the first time, binding limits for formaldehyde emissions from products apply throughout Europe.

With defined exceptions, the regulation affects almost all products from which formaldehyde can be released. This has transformed what was previously a highly sector-specific discussion into a cross-industry context.

What previously only affected individual industries has now become a Europe-wide issue for many products with the REACH extension.

CLP classification as a trigger for regulatory dynamics

A key factor behind this regulatory development is the classification of formaldehyde under the CLP Regulation (Classification, Labelling and Packaging). Formaldehyde is classified there as a carcinogen in category 1B.

This classification means that the substance is considered to be carcinogenic to humans. Even though formaldehyde is not currently included in the SVHC candidate list, its hazard classification means that it is subject to increased regulatory scrutiny.

The emission restriction under REACH is therefore part of a broader chemical regulatory system in which hazard assessment, risk minimisation and market regulation work together.

The new REACH requirements shift the focus from substance assessment to actual emissions from products – with uniform transition periods across Europe from 2026 and 2027 respectively.

From substance regulation to emissions regulation

The change in perspective is noteworthy: while REACH was originally strongly substance-centred, the new regulation specifically addresses emissions from articles.

This shifts the focus

  • away from pure substance registration
  • towards real exposure in indoor spaces
  • and actual release under conditions of use

This approach affects not only manufacturers of chemical precursors, but all companies whose end products can emit formaldehyde.

Transition periods and market impact

The new limit values apply with transition periods:

  • from August 2026 for furniture and wood-based materials
  • from August 2027 for interior fittings of road vehicles

This phasing-in period is intended to enable companies to adapt processes and develop testing strategies. At the same time, it creates a uniform framework across Europe that reduces distortions of competition and increases transparency along supply chains.

The strategic importance for manufacturers

The new REACH regulation is more than just a technical adjustment of limit values. It marks a step towards more harmonised emission requirements in the European single market.

For manufacturers, this means:

  • higher requirements for documentation
  • greater integration of emission measurements into quality processes
  • closer integration of development, production and compliance

Companies that establish structured testing strategies at an early stage not only achieve regulatory certainty, but also position themselves for long-term stability in the market environment.

Classification for practical use

Regulatory developments show that emission control is increasingly becoming part of standard industrial processes. Anyone who has formaldehyde in their product portfolio or process chain must make emissions measurable and documentable.

With measurement technology solutions for laboratory and inline applications, Fagus-GreCon supports manufacturers in systematically integrating regulatory requirements into their quality assurance processes.
