Counterfeit consumer good

Counterfeit consumer goods are goods illegally made or sold without the brand owner's authorization, often violating trademarks. Counterfeit goods can be found in nearly every industry, from luxury products (including designer handbags and watches) to everyday goods like consumer electronics and pharmaceuticals. Typically of lower quality, counterfeit goods may pose health and safety risks.

Various organizations have attempted to estimate the size of the global counterfeit market. According to the OECD, counterfeit goods made up approximately 2.5% of global trade in 2019, with an estimated revenue of $464 billion. Sales of counterfeit and pirated goods are projected to reach €1.67 trillion (approximately US$1.89 trillion) by 2030.

Despite the illegality, many counterfeit goods, especially fashion items such as knockoff handbags, watches, shoes and unlicensed sports jerseys, both with and without noticeable errors in spelling or materials, are sold throughout the world. They are purchased by locals and tourists, typically at street markets or through online retailers, at a fraction of the cost, and the quality varies.
