Cement and cementitious mixtures may
not be used or placed on the market if
the soluble chromium VI content in the
dry mass of the cement after hydration
exceeds 2 mg/kg.
In the EU, the chromium(VI) content of
leather articles in contact with the skin is
limited to a maximum of 3 mg/kg.
Products exceeding this limit may not be
placed on the market.
