The document discusses how marketers classify products. It outlines that products are classified based on durability and tangibility into non-durable goods, durable goods, and services. Non-durable goods are consumed quickly, durable goods last longer, and services are intangible. Consumer goods are further divided into convenience goods, shopping goods, specialty goods, and unsought goods based on frequency and cost of purchase. Industrial goods include materials and parts, capital items, and supplies that facilitate product development or management. The classifications help marketers develop appropriate strategies for different product types.
