Helsinki, 29 September 2010 - Updated Guidance on Substance Identity will be issued by ECHA in 2011 after the first REACH registration deadline. This formal Guidance will also replace the withdrawn Practical Guide 11.

ECHA has a rolling process of reviewing the Guidance that it provides for registrants and other stakeholders. The Guidance on substance identification has now reached the point where a review is due and the process will begin early in 2011, after the first registration deadline.

ECHA produced a short section on the evaluation of crystalline forms as part of Practical Guide 11 on substance identity. This was intended to provide more detailed information to stakeholders on how ECHA will approach the evaluation of different crystalline forms in registrations, within the framework provided by the Guidance. However, Practical Guide 11 was withdrawn because parts of it were open to misinterpretation.

As a review of the Guidance itself will now take place, ECHA has decided not to re-publish the Practical Guide 11 but to await the outcome of the review before deciding whether such detailed information is necessary and, if so, the way it should be presented.

Pending the review, stakeholders should refer to the current Guidance.
