Disclaimer : we are not intellectual property attorneys etc., so this is our non-expert response to this question. Manufacturers , distributors etc. are required to give SDS's to downstream users at no charge so there is really no point in formally copyrighting them. In fact, given that HCS 2012 requires SDS's to follow a standard format and language, it is unlikely in most cases that one would be able to have an enforceable copyright. One could reasonably argue that most SDS's are derivative of previous ones or that they simply constitute a list of facts, neither of which merits an enforceable copyright.
