USP

USP is an acronym that may refer to several distinct terms. In marketing, it stands for unique selling proposition, the factor that differentiates a product or service from competitors in the minds of consumers. A USP is typically a specific benefit, feature, or value proposition that is hard to imitate, and it guides product positioning, messaging, and pricing. Critics note that USPs can be overstated or copied and that durable advantage often comes from broader execution and customer experience.

In pharmacology and quality control, USP refers to the United States Pharmacopeia, a compendium of official public standards for medicines, dietary supplements, and ingredients. The USP, together with the National Formulary (NF), is published as the USP–NF and is used by manufacturers to ensure identity, quality, strength, and purity. USP standards are referenced by regulatory agencies and can influence testing, manufacturing, labeling, and compliance.

In Brazil, USP denotes the University of São Paulo (Universidade de São Paulo), a major public research university founded in 1934. Based in the state of São Paulo, it comprises multiple campuses and faculties and is widely regarded for research output across the sciences, engineering, humanities, and medicine.

Other uses exist in specialized contexts, but these three are among the most widely encountered. The term should be inferred from context to avoid confusion.
