See Techinical advice from USGBC. I am not clear on how to document this as evrything I list in the spread sheet impacts other credits.

COMMENT: Several products include a value less than 100 in the % Reg data field. This appears to be an attempt to document an assembly when only a portion of the raw materials have been extracted regionally. Products in question include: Versa Bond Thin Set Mortar, Poly Blend Grout and Caulk, Certain Teed Insulation, Oldcastle Concrete Pavers, M and S Machine Stainless Steel Benches, and Shaw Carpets.
TECHNICAL ADVICE:
Revise the Form as necessary to ensure that assemblies have been documented correctly. If some, but not all the raw materials were extracted regionally, then the product is considered to be an assembly and documenting#credit compliance must be accomplished using two lines on the form.; The sum of the cost between the two lines must equal the total cost of the product. One line will include the percentage of the cost that was both manufactured and extracted regionally. The other line will include the percentage of the cost that was only manufactured regionally. The applicable percentage will be indicated in the % Reg data field for each line.
