Pyro-Guard Plywood (fired treated). How should i document this for MRc7? My co-worker says 100% for new wood & 0% for FSC, is this correct?

I'm finalizing my first LEED project, and I've got a question on putting in material (FSC in particular) values into the LEED Online form.

Is paint-grade molding (made from short pieces finger-jointed together to form a usable length) considered new wood or recycled wood (presumably 100% pre-consumer)?

I rec'd an invoice for a wood product stating that the product is FSC Mixed Credit, LEED Online is asking for new wood % for this product.Supplier can not provide me with % info, what should i do.

In the past, whenever I have pursued MRc7, I have always provided invoices as supporting documentation.

I have a door company that has sent me documentation that claims 98% FSC mix and another door 90% FSC mix then claims 23% New Wood and 30% New wood right on the documentation next to the FSC Mix %

I have a subcontractor that purchased COC certified materials from COC certified suppliers.

Hello. I'm pursuing this credit on a project in Mexico City.
