What characterizes raw materials in inventory?

Raw materials in inventory are characterized as basic materials that have not yet undergone any processing or transformation. These are the essential inputs required for production, serving as the foundational components from which finished goods are created. This definition emphasizes their role in the manufacturing process, where they serve as the starting point for further processing, assembly, or refinement.

In contrast to the other options, raw materials are specifically distinguished from processed materials that are ready for production or completed parts. They are not yet part of any finished product until they have been worked on or transformed into a more advanced stage in the manufacturing workflow. Furthermore, while raw materials may be used in maintenance contexts, this is not their primary characteristic; their primary function lies in being the unprocessed base materials that are essential for manufacturing operations.
