Components or parts of finished products are referred to as:

Intermediate products are components or parts that have undergone some processing but are not yet finished goods ready for sale to the end consumer. They are crucial in the production process because they serve as the building blocks used to create final products. For instance, in a manufacturing context, components like engine parts for vehicles or circuit boards for electronics fall under this category, as they require further assembly or processing before being marketed as complete products.

In contrast, upstream materials refer to earlier stages in the supply chain, typically raw materials that have not yet been processed. Raw materials are the basic, unprocessed natural resources that will eventually be transformed into intermediate goods. Secondary products represent goods that are produced as by-products of the manufacturing process, while finished products are the end goal of production that are ready for consumer use, distinguishing them from intermediate products. Understanding the role of intermediate products is essential for grasping the structure of production and supply chains in various industries.
