Question about HPDs with Content Inventory marked as GHS SDS.

LEEDv4 Reference guide mentions Globally Harmonized Systems of Classification and lableing of Chemical rev.6 (2015)(GHS) as an approved documentation. 

If a HPDv2.1 has content inventory marked as 'per GHS SDS', is it safe to assume that it was per rev.6 (2015) stds?
