All companies that had pre-registered Silicon were contacted and asked to indicate if their substance fitted with the description in the proposed ID card. The enquiry was closed on 3 April 2009.
Companies that were of the opinion that their substance did not meet the criteria as described in the substance ID card were invited to demonstrate the sameness of their particular substance, if there was any doubt.
When there was no doubt that their particular substance was NOT covered by the substance ID card, companies had to form or join a different SIEF.
The detailed ID card for Silicon is attached.
