We have always used industry standard steel letters as backup for structural steel recycled content from people like Nucor, Atlas Tube, Gerdau, etc. In a recent review, reviewers indicated that all of these letters were not compliant because they are based on "averages". They indicated the requirement is for actual, product-specific recycled content values. We were advised to use the standard 25% for all of these steel products. 

One letter that did not use the word average in the text was exempted from their comment even though I'm sure they use exactly the same industry standard process to provide their percentages. 

How are the rest of you dealing with this? It does not seem reasonable to expect that we could obtain a specific recycled content percentage for steel plate or angles or bars used on a particular project from a national provider.

If we have lost the ability to use the higher recycled content values of structural steel, along with all the regional materials that don't have other attributes to claim, it appears that this credit will become another of those efforts that have been disincentivized by v4. Is anyone actually achieving this credit even substituting v4.1 with a 20% threshold and without the 30% enclosure cap? If so, how?
