Differences between the EU and the United Kingdom in the classification of talc

The European Union and the United Kingdom have taken different paths in the assessment of talc and its potential carcinogenicity. This regulatory divergence is creating a dual compliance scenario that affects manufacturers and distributors operating in both markets.

In the European Union, the classification of talc as Carc. 2 (H351) remains in place under the Regulation (EC) Nº1272/2008 on classification, labelling and packaging of substances and mixtures (CLP Regulation). The decision is based on epidemiological studies where associations were observed between prolonged exposure to talc and specific risks identified in certain occupational environments. The European interpretation follows a precautionary approach supported by the overall weight of evidence.

In the United Kingdom, the situation has evolved independently following the implementation of UK REACH. The British authority reviewed the same scientific information and concluded that the available data do not support adopting the European classification. The UK assessment highlights elements such as variability in the samples examined, the possible presence of mineral impurities that may influence results and the lack of homogeneity in exposure conditions across the reviewed studies.

These differences create a complex practical scenario. In the European market, products containing talc must include the labelling associated with a substance classified as a suspected carcinogen, while in the United Kingdom this requirement does not apply. Companies must therefore maintain differentiated documentation, update their safety data sheets depending on the destination market and adapt hazard communication to avoid inconsistencies along the supply chain.

Organisations that must comply with both CLP and UK REACH operate in an environment that demands constant attention, as the two systems may continue evolving. At Siam we take on this regulatory monitoring so that companies can adapt without complications and maintain clear, up-to-date and consistent documentation in situations where divergences arise, such as the current case involving talc.
