Similar to hardwoods, bamboo forests are most sustainable when only 20 percent of the bamboo is harvested in any given year, leaving the forest canopy uncompromised and the ecosystem intact. Poorly managed bamboo forests have detrimental effects on the local economy and the environment. With demand increasing for this natural resource, FSC certification of bamboo sources ensures proper harvesting to protect the local economy and the environment. Smith & Fong\'s bamboo resource was certified by the European FSC-certifier Institut f" "The project team is seeking clarification as to whether or not bamboo can be considered a compliant material under the guidelines set forth in MRc7. The bamboo products in question have been harvested and sourced by companies that possess the necessary and current certifications from the Forest Stewardship Council (FSC). This proposal is consistent with the credit intent to, ""Encourage environmentally responsible forest management"". In addition, bamboo is often used in many of the same applications as wood products, and is considered by the FSC to be a forest product despite its technical classification as a grass. Therefore, bamboo may be included in the calculations for both MRc6 and MRc7. If bamboo is added to the MRc7 calculations, all bamboo on the project (FSC or otherwise) must be accounted for in the value for all new wood-based components for the project.

Also, assuming that the 50% required for credit achievement is met, please clarify 1. whether this point can be earned by including temporary wood products in the calculation of FSC certified wood products (in addition to the permanently installed wood products), and 2. whether this point can also be earned with achievement among the temporary wood products alone (without any FSC certified wood among the permanently installed wood products but by including the non-FSC-certified permanently installed wood products in the base amounts of wood products)."

Specifically in two situations when CoC claims cannot be passed on the final invoice to the project team. In the first scenario a furniture vendor is the final installer but the cost on the invoice from the manufacturer holding the CoC does not reflect the final cost of the product (minus installation cost). In this case ins the invoice from the manufacturer sufficient, or is the history of the raw material required? In the second scenario architectural millwork is custom made and installed by a millwork company that is CoC certified, but invoices for the entire contract total, not itemized FSC items. Per guidance published in April 2008 aggregated wood totals are allowed, however, what about situations where the entire contract package is not iligible to be invoices with FSC claim? Please define for this project and as precedent how to document MR credit 7: Certified Wood." "This ruling addresses two separate documentation paths for MR credit 7: Certified Wood. The project team is asking which invoices are required to be submitted as documentation for the Certified Wood credit. The invoice required for documentation of MRc7 is the invoice for wood products sold to the project contractors or subcontractors who do not modify the product off-site are required to be submitted. Invoices from farther up the supply chain (documenting the history of the product) do not need to be provided. In the case of a furniture dealer that purchases furniture and installs it on-site and does not have a COC certification, they may provide their invoice to the end user along with a letter from the furniture manufacturer which states the manufacturer COC number and the FSC label (FSC pure, FSC Mixed Credit, FSC Mixed NN%) for each piece of furniture.\n The project team is inquiring if the aggregated totals for new wood material costs as defined in the April 2008 wood documentation guidance must be in an invoice from the installer, or if the cost amounts may be submitted separate from an invoice. Yes, documentation of aggregated FSC and non-FSC certified wood may be aggregated and submitted via separate documentation if the following requirements are met:\n An alternative documentation process is available for architectural woodworkers (manufacturers of millwork, casework, and furniture) who supply custom wood products to the project. The purpose of this alternative process is to allow FSC-certified materials used in a custom millwork, casework, or furniture package to contribute toward the credit even if the entire package is not eligible to be invoiced with a FSC claim. Documentation for this alternative process must meet all of the following requirements:\n - The woodworker (whether an individual or a company) must be FSC CoC certified, and the CoC certificate number must appear on the project invoice.\n - The woodworker must install the custom millwork, casework, or furniture.\n - The woodworker’s invoice must isolate product costs from installation costs.\n - The woodworker must provide a document, separate from the project invoice, detailing FSC-certified wood materials used and total cost of wood materials used. (The woodworker does not need to provide itemized material cost calculations but must maintain calculation records for auditing purposes by the FSC certifying body.)\n - The contract cost may include assembly labor but must exclude on-site labor (see MR Overview, Determining Product Cost).\n The project team should complete a spreadsheet itemizing wood components by cost and identifying FSC-certified and noncertified components to determine overall contributions to the credit, to be entered into the MR calculator. Calculate the FSC-certified contribution value toward the credit by multiplying the percentage of FSC-certified wood by the overall value of the contract. Calculate the percentage of FSC-certified wood by dividing the cost of FSC-certified wood by the total cost of the wood. Submit the FSC-certified contribution value as well as the total contract amount. Include the woodworker’s CoC certificate number, invoice, and itemized costs."

Products identified as FSC Mix Credit or FSC Mix [NN] % also have pre- or post-consumer recycled content, the latter of which is commonly reported separately by the product manufacturer. In these instances the project team must choose whether to classify the product (or some fraction of the assembly) as FSC certified or as recycled content; the material cannot contribute to both claims simultaneously.
