Casework

If the casework manufacturer is FSC CoC certified, which they should be, then they are probably operating under the FSC percentage system. If so, they would derive -- and report on their invoice -- the FSC percentage of the total casework package by dividing the weight (or volume) of FSC input materials by the total weight (or volume) of the wood used in the package, backing out the non-wood components (in your case, the hardware and the bamboo panels). If the casework manufacturer needs more assistance in figuring this out, they can contact me directly: jason@jasongrantconsulting.com

Unfortunately, if the casework fabricator doesn't have CoC, then the FSC-certified wood they used doesn't count. As Doug points out below: The February 2, 2011 Addenda to (LEED 2009 First Edition BD+C) makes the following clarification: http://www.usgbc.org/Docs/Archive/General/Docs6392.pdf: "Entities that install an FSC-certified product on the project building/site (typically project contractors or subcontractors, but also furniture installers and the like), do not require CoC certification as long as they do not modify the product’s packaging or form except as is required for installation. Contractors and sub-contractors that temporarily possess FSC-certified material prior to installation should be careful not mix or contaminate the FSC-certified material with non- FSC-certified material."
