CoC certification requirement for Project General Contractor.

The LEED BD+C addenda states the following: - " 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." - This project includes some simple wood shelves. The contractor does not have a CoC certification. Can the contractor receive the FSC panels from a CoC certified supplier to the project site and modify them on site to construct the shelves without a CoC? The construction will entail cutting to size the FSC panels, sanding and sealing, and installing on wall.
