Which of the following is NOT classified as a consumer product?

In the context of consumer products, the classification system typically includes convenience, shopping, and specialty products, all of which are types of goods that consumers purchase for personal use. Convenience products are items that are bought frequently with minimal effort, shopping products are those that consumers compare for quality and price before purchasing, and specialty products are unique items that consumers seek out and are willing to make a special effort to acquire.

Derived products, on the other hand, refer to goods whose demand is derived from the demand for other products. They are typically associated with business or industrial markets rather than individual consumers. For example, the demand for steel is derived from the demand for automobiles, as steel is a raw material used in their production. Thus, derived products do not fit within the consumer product classifications and help highlight the distinctions in market segmentation between consumer-focused products and those aimed at businesses. Consequently, derived products do not qualify as consumer products, making this classification the correct answer.
