Upon further clarification from the submitter, they just wanted to know the difference between commercial and non-commercial terms and conditions. I referred him to the various commercial and non-commercial clauses to examine the language, similarities, and differences.

Starting with FAR 52.212-4, which is the primary commercial clause, there are equivalent non-commercial clauses that correlate to the various paragraphs of the commercial clause. For example, FAR 52.212-4 (a) provides terms for inspection and acceptance. Similar language exists at FAR 52.246-2 (supplies) and FAR 52.246-3 (services) for non-commercial items.  

 Other examples are: FAR 52.212-4 (c) and the Changes Clause, FAR 52.243-1;   FAR 52.212-4 (d) and the Disputes Clause, FAR 52.233-1; and FAR 52.212-4 (f) and the Excusable Delay Clause, FAR 52.249-13.  I also provided guidance on FAR 52.212-4 (l) and FAR 52.212-4 (m), the termination paragraphs with FAR 52-249-2 (Fixed Price Convenience) and FAR 52.249-8 Fixed Price Default.
