We've gotten a response from reviewers that HPDs we've submitted "do not include compliant lists of materials ingredients" and then they call out CASRN 65997-19-5, which is steel in our USG drywall suspension system, and CASRN 65997-17-3, which is fiberglass in our USG Sheetrock and a few others products. The reviewers say the manufacturer has to break out these materials, which have unique CASRN, into their constituent parts. Have other people gotten this kind of response? Is there a list of CASRN that aren't detailed enough?

Nathan, I'd like to follow up on this. I think I know what GBCI is looking for here, but I'd like to get into a little more detail and perhaps discuss directly with them. Can you send me specific reviewer communications - troberts (at) hpd-collaborative.org? The issue (probably) is that steel and fiberglass are complex mixtures of multiple chemicals, and are not really accurately represented in the CAS RN system. However, the fact is that they do appear and manufacturers use those CAS numbers. GBCI is probably trying to do some quality control here.
