Counterfeiting generally involves creating an imitation of a genuine item that closely resembles the original to deceive others into believing it is authentic.
Counterfeit products are often made to take advantage of the higher value of the original product, typically using lower-quality materials or production methods. Counterfeit food, drinks, medicines, and personal care products can contain harmful or inactive ingredients, causing anything from mild issues to serious, life-threatening ones. Counterfeit footwear, clothing, and accessories have been found to contain high levels of

The colloquial terms "dupe''"'' (short for "duplicate") or "knockoff''"'' are often used interchangeably with "counterfeit," though they have different meanings. Dupes and knockoffs generally mimic the physical look of other products without copying the brand name or logo of a trademarked item, unlike counterfeits. Despite this distinction, counterfeits are frequently misleadingly marketed as dupes.

), the presence of counterfeit goods in global trade has grown substantially. In 2005, counterfeit and illegally copied products accounted for up to $200 billion in international trade. This figure rose to $250 billion by 2007, representing 1.95% of world trade, up from 1.85% in 2000. By 2019, counterfeit and pirated goods made up approximately 2.5% of global trade, valued at an estimated $464 billion.
In the EU, imports of counterfeit and pirated products reached as high as €119 billion (approximately $134 billion), accounting for up to 5.8% of total imports that year.
The increase in counterfeit goods sales, driven by the rise of globalized supply chains and e-commerce, is enabled through the use of small packages, sometimes referred to as
de minimis shipments.
Counterfeit goods purchased from e-commerce websites or social media apps are shipped in small packages to bypass
customs inspections and exploit de minimis benefits, such as duty-free imports and expedited customs processing, allowing them to reach buyers directly. In 2023, 92% of counterfeit seizures in the U.S. involved small packages.China (including Hong Kong) is a major source of counterfeit goods, responsible for an estimated 80% of the world’s counterfeits, contributing over 1.5% to its GDP, and accounting for 84% of all counterfeit items seized by

Other significant sources include India, Thailand, the Philippines, Turkey, Vietnam, Colombia, Mexico, and the United Arab Emirates.

. Most commonly, these markets originate out of areas where the inability to buy popular streetwear brands has fueled more sophisticated markets for counterfeit goods. These markets have spawned the emergence of a tribe of widely available
copycat brands.
In countries like North Korea and Russia where trade sanctions were imposed in the past to prevent the importation of popular brands, demand was stimulated for available counterfeit alternatives. The economic standing of a country or region also contributed to the demand for these products as the average consumer can't afford
luxury prices but will gain the same social impact purchasing a
knock-off whose quality is almost indistinguishable from the original's.
Luxury streetwear is out of reach for many people, not just because of international sanctions and low wages, but because exclusivity is built into its business model. Social and cultural forces are driving the unique fashion scene. In particular, social media has a huge influence on over these markets giving people images of things they can't own and further fueling the desire to obtains certain "
hyped" items by any means accessible.

* Marking technologies
* Chemical and physical technologies
* Mechanical technologies
* Technologies for digital media
The
International Standard Organization has also published standards related to the implementation of anti-counterfeiting solutions, including ISO 12931
