My question is for 2.0, but I think the content is still relevant to 2009.

We have been asked to provide calculations for how the raw materials were determined for some products and told to reference the assemblies’ information from MRc4 to do so. Manufacturers’ letters or cut sheets have also been requested.

The documentation for these products states that xx% was manufactured (or extracted) within 500 miles. Is this sufficient? Also, the credit asks for product cost but not material cost. If 98% of the product was extracted locally, do I input the whole cost towards the credit or just 98% of the cost? Thanks!
