Nine in ten firms in Mexico now spot fakes online, with medicines leading a piracy surge that endangers patients and undermines trust.
Online piracy used to mean bootleg DVDs and dodgy music downloads. For many companies operating in Mexico, the real threat now sits in shopping carts, not on torrent sites.
A new edition of the American Chamber of Commerce of Mexico’s piracy survey finds that nine out of ten member companies have detected counterfeit or pirated versions of their products on e-commerce platforms. The study, carried out with the research firm Lexia and intellectual property specialists Clarke Modet, reports that more respondents see piracy online than in street markets or formal stores. In digital sales, the survey says, pirated goods have become the rule rather than the exception for many brands.
The shift is not only about where fakes are sold, but what is being copied. After years in which apparel and footwear dominated the rankings, companies say the most counterfeited items in Mexico’s online marketplaces are now medicines and medical devices. Food and drink products, personal care items, toys, school supplies and industrial equipment follow behind.
Researchers also asked where these knock-offs come from. Two-thirds of companies believe most pirated goods entering their market are imported, with additional volumes produced or assembled inside the country. The problem is most visible in large urban and industrial states such as Mexico City, Jalisco and the State of Mexico. Still, for brands selling nationwide, the message is blunt: if they sell online, they are competing with a shadow version of their own catalogue.
Online counterfeit medicines Mexico and the health risk
On paper, medicines should be among the most carefully controlled products in any market. The new piracy data suggests they have become one of the most vulnerable.
According to the AmCham survey, pharmaceuticals and medical devices now occupy the top spot among product categories affected by online piracy in Mexico. That means everything from everyday treatments to specialised therapies can appear on e-commerce sites in packaging that looks legitimate but does not come from authorised supply chains.
Global evidence shows why that matters. The World Health Organization estimates that at least one in ten medical products in low- and middle-income countries is substandard or falsified, and notes that these products are often sold online or through informal markets. Such medicines may contain too little active ingredient, the wrong ingredient, or none at all, and can trigger severe side effects or complete treatment failure.
International trade studies echo that warning. An analysis by the OECD and the EU Intellectual Property Office found that e-commerce has become a key channel for counterfeit goods worldwide, including fake and substandard medicines, as criminal groups exploit small parcel shipments and anonymous seller accounts.
Mexico’s own health authorities are now seeing the same pattern. On 31 October 2025, the Federal Commission for Protection against Sanitary Risks (COFEPRIS) issued a nationwide health alert over the illegal commercialisation of medicines on e-commerce platforms, websites and mobile apps. Regulators reported finding falsified or unregistered products offered at prices below the market and sold without prescriptions, including high-cost treatments for cancer and other serious conditions.
COFEPRIS warned that these medicines may be counterfeit, adulterated, stolen, or diverted from official channels, and that their origin, storage conditions, and content are unknown. The agency urged the public not to buy medicines that normally require medical supervision from online platforms that do not ask for a prescription, that offer unusually low prices, that display labels in foreign languages, or that lack a Mexican sanitary registration.
The AmCham survey adds a commercial angle to that health warning. Companies say price is the main hook: many report that pirated products sell for around half the cost of the genuine item. For families struggling with household budgets, a medicine that appears identical but costs 50 percent less can look like a lifeline. That is where online counterfeit medicines Mexico turns from a trade problem into a public health risk, especially for patients dealing with chronic or life-threatening illnesses.
Industry representatives in Mexico’s research-based pharmaceutical sector say the impact is already visible. The national association of innovative drug makers, AMIIF, has raised alarms that fake medicines aimed at “devastating” diseases are often detected only after they reach patients. Its leaders argue that current reporting channels are too slow and that long, inconclusive court proceedings discourage companies from filing complaints when they do spot illicit products.
That erosion of trust goes beyond any single counterfeit box. When patients hear about fake treatments circulating online, they may start to doubt even legitimate supplies, undermining adherence to therapies and straining an already pressured health system.
Mexico’s enforcement gap in the digital marketplace
Mexico is not ignoring piracy. In recent months, federal authorities have stepped up raids against physical markets known for selling counterfeit goods. A high-profile operation at the Izazaga 89 complex in Mexico City and a follow-up action in Sonora led to the seizure of about one million illicit items worth an estimated 150 million pesos, backed by the National Guard and the Mexican Institute of Industrial Property.
Yet while warehouses are being cleaned out, the online side of the problem remains harder to pin down. The United States Trade Representative’s 2025 Special 301 Report moved Mexico onto its Priority Watch List, citing unresolved concerns over enforcement against counterfeiting and piracy and over the protection of pharmaceutical-related intellectual property. The report notes that criminal investigations and prosecutions for trademark counterfeiting and copyright piracy appear to have stalled, even as online piracy, including illicit streaming and other digital channels, continues.
Business groups in Mexico describe a similar gap. In the AmCham survey, companies identify e-commerce marketplaces and social media platforms as the main channels for counterfeit sales. Many want faster response times when they flag suspect listings, tougher seller verification, and better access to data that would let them trace networks rather than remove isolated posts. For online marketplaces, that would mean investing more in proactive detection and cooperating closely with both brands and regulators.
Authorities have tried to shape platform behaviour as well as conduct raids. Mexico has introduced a voluntary code of ethics for e-commerce suppliers and a digital trust seal aimed at distinguishing compliant online sellers from the rest, part of a broader push to professionalise the digital economy and encourage legal trade.
Still, the core incentives behind piracy remain powerful. The AmCham study describes a market in which pirated goods advance in parallel to the formal economy, following a business-like logic supported by high social tolerance, strong economic rewards and institutions that may look robust on paper but often act slowly in practice. For counterfeiters, that combination keeps the risk-reward balance attractive.
For consumers, the picture is more complicated. Surveys suggest only about a third of companies believe buyers can reliably tell the difference between original and fake products. At the same time, the offer of fast delivery, sharp discounts and slick product photos can make an unauthorised seller look every bit as legitimate as a licensed pharmacy or brand store.
Health authorities argue that the safest option remains buying prescription medicines through established channels that require medical evaluation, prescriptions and proof of sanitary registration. That advice may feel out of step with the speed and convenience of modern e-commerce, but the recent COFEPRIS alert shows how much can go wrong when life-saving therapies are reduced to discounted items in an online storefront.
The struggle against online piracy in Mexico is now about far more than brand protection. It sits at the intersection of trade, health and consumer rights, where each fake box sold chips away at trust in both the digital marketplace and the medicines that millions of people depend on. Whether the combination of tougher enforcement, tighter platform rules and better public awareness can tilt that balance back remains the question hanging over every click.
