Hello there,
Option 1 accepts the following as documentation:
- Document to demonstrate the chemical inventory of the product to at least 0.1% (1000ppm).
- The manufacturer has published complete content inventory for the product following these guidelines:
- A publicly available inventory of all ingredients identified by name and Chemical Abstract Service Registration Number (CASRN).
- Materials defined as trade secret or intellectual property may withhold the name and/or CASRN but must disclose role, amount and GreenScreen benchmark, as defined in GreenScreen v1.2.
A manufacturer sent me a list of ingredients with different percentages varying from 0.15% to 73.05%. How do I tell if the ingredients of a product is disclosed to 0.1%?
Thank you!

Very simple answer - if you don't trust a manufacturer you don't specify a product. Hopefully if it is reputable building products manufacturer you should assume it is giving you accurate information on the ingredients in a product and is well aware of the requirements to report to 0.1%

I have the same question. The manufacturer is trust worthy, but if the MSDS doesn´t specify it is disclosed to 0.1%, how can I identify the scope of disclosure?

Hi Ashley, were you able to submit this material to LEED and was it accepted without further clarifications?

I'd like to know what to look for on manufacturer inventories to be sure they demonstrate the chemical inventory of the product to at least 0.1% (1000 ppm) too. Has anyone gotten clarity on that?
