The reporting that I have used for steel on all my projects has been successful and met the expectations of the reviewers in terms of the point of manufacture and extraction. However, I am currently working with a new steel fabricator that disagrees and I'm struggling to find a clear, concise answer for why I don't think the documentation they have been using will still be acceptable. There are several new threads on here with similar comments, which always makes me feel better. I like knowing I'm not alone in the fog.

I use the steel mill for manufacturing and the scrap yard as the extraction point. The fabricator has been using their location as manufacturing and the steel mill as the extraction point.

Technically, the addenda and other resources seem to support the use of their fabrication yard as the manufacturing location, but will the reviewers accept the steel mill as the point of extraction? My recent experience tells me no, but the actual verbiage of the addena says manufacturing is the point of final assembly and extraction is the point at which it is packaged for delivery to the manufacturer, which would be the steel mill.

Is there anything I can reference to clarify this issue as it relates to steel?
