REACH Transported Isolated Intermediates
The EU regulatory framework for chemicals is set by the REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) regulation No 1907/2006. Many of the products we sell are classified under REACH as Transported Isolated Intermediates, and additional criteria must be met for their sale.
The registration information requirements for intermediates are generally reduced and there is no requirement to carry out a chemical safety assessment.
To fulfil the definition of an intermediate, the registered substance needs to be transformed into another substance and manufactured and used under strictly controlled conditions at chemical manufacturing sites. The status of a substance as an intermediate is not specific to its chemical nature but to how it is used after manufacture.
Consequently, the following conditions must be met:
- The synthesis of another substance takes place using that intermediate
- The substance is used under strictly controlled conditions, as defined in REACH article 18(4)
- An End User Declaration is completed by the customer
Further information on intermediates and the information requirements for intermediates is available on the ECHA website and in the Practical Guide.
