When did made in come into use?

The term "made in" began to appear in the late 19th century, particularly as countries sought to promote their manufactured goods and establish brand identity. It became more prominent with the rise of industrialization and globalization, as products were increasingly traded internationally. The phrase often indicated the origin of products, helping consumers make informed choices about quality and authenticity. By the early 20th century, "made in" labels became a standard practice on consumer goods worldwide.
