NC-v4.1 MRc4:Material Ingredients

3rd Party Verified Manufacturer Inventory & Product Lens?

Hello,

   I'm looking for confirmation on what counts as 3rd Party Verification for these two types of Material Ingredient Reports:

  • Manufactuer's Inventories: I'm specifially looking at Sherwin-Williams MIs that have "verified by NSF" in the top right corner. Is this adequate verification?
  • Product Lens: I'm looking at a Product Lens that lists "Assessor: MBDC". Does this count? Does this mean all Product Lens certifications are 3rd Party Verified? 

Thank you in advance!

Hi Katrina, 
Yes, Sherwin Williams being verified by NSF is 3rd party.  Their Product Lens certificates are typically by UL. You can see their logo in the upper left corner of the certificate.  Here is an E-book with products that meet option 2's and their weights:  https://getgreenbadger.com/resource/leed-v4-1-epd-and-mir-option-2-product-guide-usgbc-winter2022/
