What documentation must be completed to support a determination that a product is commercial?

The correct choice is to complete a Commercial Item Determination (CID) to support a determination that a product is commercial. A CID is a formal document used in government contracting to assess and justify whether a product or service meets the criteria of a commercial item as defined by the Federal Acquisition Regulation (FAR). This determination is essential because it influences the procurement process, including the applicable regulations and pricing structures.

A CID typically includes an analysis of the market, specifications of the product, and evidence that similar items are available in the commercial marketplace. This documentation ensures compliance with government policies and can lead to streamlined acquisition processes and potential cost savings.

While other documents may play roles in the overall contracting process (for example, a Contract Administration Plan outlines how the contract will be managed, and a Source Selection Plan details the process for selecting bidders), they do not specifically serve the function of establishing a product's status as a commercial item. A Price Negotiation Memorandum may summarize pricing discussions but does not determine commercial item status. The CID is uniquely focused on confirming the commercial nature of the product or service.
