REACH Statement
Registration of Substances:
After careful review of the legislation and specifically the definition of an “article” as defined in EC
Regulation 1907/2006, Title II, Chapter 1, Article 7.1(a)(b), it is our current view Multi-Tech Systems, Inc.
products would be considered as “articles”. In light of the definition in § 7.1(b) which requires
registration of an article only if it contains a regulated substance that “is intended to be released under
normal or reasonable foreseeable conditions of use,” our analysis is that Multi-Tech Systems, Inc.
products constitute nonregisterable articles for their intended and anticipated use.

“REACH” requirements of less than 0.1% (w/w) for each substance. If new SVHC candidates are
published by the European Chemicals Agency, and relevant substances have been confirmed, that
