Pangolin Trafficking Routes and Traditional Medicine Demand

Pangolins are the most trafficked wild mammals on Earth. Hundreds of thousands have been taken from the wild over the past two decades, funnelled through criminal networks stretching from African savannas to Asian markets, driven almost entirely by demand for a product — their scales — that has no proven medicinal value whatsoever.

The Scale of the Problem: Most Trafficked Mammal on Earth

The designation of pangolins as the world's most trafficked mammal is not rhetorical. It is based on seizure data compiled by organisations including TRAFFIC (the wildlife trade monitoring network), UNODC (the United Nations Office on Drugs and Crime), and the IUCN SSC Pangolin Specialist Group. Between 2000 and 2019, at least 895,000 pangolins are estimated to have been trafficked globally based on recorded seizures alone. Because seizures represent only a fraction of actual trade — law enforcement experts typically estimate that between 10 and 20 percent of illegal wildlife shipments are intercepted — the true number of pangolins removed from the wild during this period likely exceeds one million animals.

A single large seizure can involve tens of thousands of animals or tonnes of scales. In 2019, Singapore authorities intercepted two shipments from Nigeria within a single week: one containing 12.7 tonnes of scales (representing approximately 25,000 pangolins) and another containing 12.9 tonnes. These were among the largest single seizures ever recorded, and they occurred back-to-back, suggesting that the trafficking network was operating at industrial scale with minimal concern about detection.

The trend in seizure data reveals a disturbing shift. In the 1990s and early 2000s, most seized pangolins were Asian species — the Sunda pangolin and the Chinese pangolin — indicating that Asian populations were the primary target. As those populations collapsed under hunting pressure, traffickers shifted their operations to Africa. Since approximately 2012, African pangolin species — primarily the white-bellied pangolin, the black-bellied pangolin, and Temminck's ground pangolin — have dominated large seizures, indicating that the trade has now significantly depleted Asian wild populations and is now working through African ones.

Demand Drivers: Traditional Chinese Medicine

The primary driver of pangolin trafficking is demand for scales in traditional Chinese medicine (TCM). In TCM theory, pangolin scales (called chuan shan jia in Mandarin, meaning "mountain-piercing armour") are classified as a drug that moves blood, reduces swelling, expels wind, and promotes lactation in nursing mothers. These therapeutic frameworks are derived from pre-scientific medical traditions that associated the scale's physical properties — its hardness, its association with burrowing underground, its historical rarity — with particular physiological effects through principles of sympathetic magic and pre-modern theories of bodily function.

TCM practitioners have used pangolin scales in formulations for centuries, and the demand has historically been met through legal trade in regulated quantities. The problem is that the belief in the scales' medicinal value has persisted and grown alongside rising incomes in China and Vietnam, while wild pangolin populations have simultaneously declined, creating a scarcity premium that has increased the price of scales dramatically and expanded the financial incentive for trafficking.

In 2020, China's National Medical Products Administration removed pangolin scales from the official list of approved TCM ingredients — a significant regulatory step that removed the legal framework for pharmaceutical use. However, demand has not collapsed in response. Some practitioners continue to prescribe scales through informal channels; the scales continue to appear in market surveys conducted by researchers and NGOs; and pangolin meat, sold as a luxury food item rather than a medicine, continues to attract buyers in high-end restaurants in Vietnam and China. Regulatory change has not yet translated into behavioural change at the consumer level.

The Scientific Reality: No Proven Medicinal Value

From the perspective of modern pharmacology and medicine, pangolin scales have no medicinal value. This is not a controversial or contested scientific position — it is the conclusion of every peer-reviewed analysis that has examined the chemistry and pharmacology of pangolin scale keratin. The scales are composed of keratin, a protein that is chemically identical in structure and biological activity to the keratin in human nails. When consumed, this keratin is either not digested and passes through the gut unchanged, or it is broken down into amino acids that are nutritionally indistinguishable from those obtained from any dietary protein.

There is no compound unique to pangolin scales that could account for the therapeutic effects attributed to them. The placebo effect and the natural resolution of the conditions being treated (many of which improve with time regardless of treatment) have almost certainly accounted for the anecdotal efficacy reported by practitioners and patients over the centuries. The same placebo dynamic underlies much of the perceived efficacy of other TCM ingredients derived from endangered species, including rhino horn and tiger bone.

This is not an argument that all traditional medicine is without value. Many pharmaceutical drugs have been derived from plants and animals used in traditional medical systems worldwide, and ethnopharmacology is a productive field of scientific research. The specific claim being rejected is that pangolin scales contain any pharmacologically active compound that justifies their use — a claim that cannot survive chemical analysis.

Main Trafficking Routes: Africa to Asia

Pangolin trafficking has evolved from a disorganised, locally based trade into a sophisticated transnational criminal enterprise. The dominant trafficking corridor runs from sub-Saharan Africa — primarily West and Central Africa, with growing contributions from East and southern Africa — through transit countries to China and Vietnam. Understanding this route requires tracing the network from harvest to consumer.

At the source end, pangolins are captured by local hunters who may be operating opportunistically (finding pangolins while hunting other species) or specifically targeting pangolins in response to orders and price signals from middlemen. In many source communities, the price offered for a live pangolin or a kilogram of scales represents a significant multiple of daily agricultural or fishing income. This economic disparity is a major vulnerability: poverty and limited livelihood alternatives make poaching an attractive risk even in communities where wildlife laws are relatively well enforced.

From the hunter, pangolins or their scales pass through a chain of middlemen — local buyers, regional aggregators, exporters — before reaching major shipping hubs. In West Africa, key export hubs include Lagos (Nigeria) and Douala (Cameroon). In East Africa, trafficking has been documented through Kenya, Tanzania, and Mozambique. In southern Africa, seizures have occurred at ports in South Africa, particularly Durban and Cape Town. From these hubs, shipments travel by sea freight — hidden in shipping containers — or occasionally by air freight, concealed within legitimate commercial cargo.

Common concealment methods used in shipping containers include mixing scales or whole frozen pangolins with timber, fish meal, scrap metal, or other bulk commodities that are difficult to inspect thoroughly. The sheer volume of global container shipping — tens of millions of containers per year — means that customs authorities can physically inspect only a small fraction of shipments, typically between 2 and 5 percent even in countries with well-resourced customs services. This gives traffickers extremely favourable odds of successful transit.

Source Countries: Africa's Pangolin Nations Under Pressure

Nigeria has emerged as the single largest source and transit country for African pangolin trafficking. Its large and relatively unmonitored wild lands, extensive commercial port infrastructure, and a trafficking network embedded within established trade routes to Asia make it the central node of the African pangolin trade. Nigerian trafficking networks have been documented sourcing pangolins not only from within Nigeria but from across Central Africa — Cameroon, Gabon, Republic of Congo, Democratic Republic of Congo — and transporting them through Nigerian ports.

Cameroon is both a major source country and a transit hub, particularly for pangolins sourced from Central African Republic, Chad, and the wider Congo Basin. The dense forests of the Congo Basin support populations of white-bellied and black-bellied pangolins that are particularly targeted by tree-climbers with dogs. Seizures at Cameroonian borders and at Douala airport have been documented by both national authorities and TRAFFIC researchers.

South Africa presents a different profile. The Temminck's ground pangolin (Smutsia temminckii) is the species present in southern Africa, and while South Africa has relatively strong wildlife law enforcement compared to many African countries, it is not immune to trafficking. South African pangolins are captured within the country and transported northward into sub-Saharan networks, or pangolins from Zimbabwe and Botswana are transited through South Africa for export. South Africa is also a consumer of pangolin parts in some traditional medicine practices, adding a domestic demand dimension to the trade.

Zimbabwe has been identified in multiple intelligence reports as a country where pangolin trapping has increased significantly since 2015, driven by the economic pressures of currency instability and limited rural livelihoods. Pangolin traffickers in Zimbabwe have been documented operating in areas adjacent to national parks, taking advantage of wildlife corridors that pangolins use but that are difficult for rangers to monitor continuously.

Destination Countries: China and Vietnam

China is the largest market by volume for pangolin scales. Despite the 2020 delisting of pangolin scales from official TCM pharmacopoeia, consumer surveys conducted by organisations including WildAid and the China Biodiversity Conservation and Green Development Foundation have found persistent demand among older consumers, practitioners in Traditional Chinese medicine, and affluent individuals who associate pangolin consumption with status and wealth. The Chinese market is not monolithic: urban, educated younger consumers show substantially lower rates of demand compared to older cohorts and rural populations, and public awareness campaigns have had measurable effects in reducing stated intention to consume pangolin products among younger demographics.

Vietnam is the second major destination and in some respects the more intractable market problem. Vietnamese demand spans both scales (used in traditional medicine) and meat (consumed in restaurants as a luxury food and status symbol). The Vietnamese government has nominal CITES obligations and has made some regulatory interventions, but enforcement against high-end restaurants serving pangolin has been inconsistent. Consumer surveys in Vietnam show that pangolin consumption is associated with celebration, business entertainment, and the conspicuous display of wealth — cultural drivers that are difficult to address through regulation alone.

Methods: How Traffickers Move Pangolins

Traffickers have developed an array of methods to move pangolins through detection systems. The most common for large-scale trade is concealment within shipping containers. Scales are typically dried, bagged, and mixed within consignments of other goods. Whole frozen pangolins have been found hidden within frozen fish consignments, within industrial machinery crates, and among carved wooden objects. The use of false documentation — mislabelling species, declaring protected animals as unprotected look-alikes, or creating fraudulent CITES export permits — is common in the trade.

Corruption of customs and port officials is documented in multiple source and transit countries. In some West African ports, investigators have found evidence of systematic payments to officials who ensure that specific containers are not selected for inspection. The involvement of organised crime groups — sometimes the same networks that traffic narcotics, firearms, or human beings — adds a layer of sophistication and violence to the trade that overwhelms poorly resourced wildlife enforcement agencies.

Couriers carrying small quantities of scales or live pangolins as personal baggage have also been intercepted at airports. In these cases, scales are often distributed among multiple pieces of luggage, concealed within personal items, or declared as antiques or food products. Some trafficking cases have involved diplomatic couriers exploiting customs privileges, though these cases are rare and politically sensitive.

CITES Listing: Legal Protections Since 2016

CITES — the Convention on International Trade in Endangered Species of Wild Fauna and Flora — is the primary international legal framework governing wildlife trade. Species are listed on one of three appendices based on their status and the level of trade controls warranted. Appendix I is the highest protection level, prohibiting all commercial international trade in specimens of listed species.

All eight pangolin species were uplisted to CITES Appendix I at the 17th Conference of the Parties in Johannesburg in September 2016, with the decision entering into force in January 2017. Prior to 2016, the four Asian pangolin species were already on Appendix I, while the four African species were on Appendix II (which allows regulated trade). The 2016 decision extended the full trade ban to all species, closing a loophole that had sometimes been exploited by traffickers who mislabelled Asian scales as African.

CITES listing does not automatically translate into domestic law — each signatory country must implement the protections through its own national legislation. The quality of implementation varies significantly. Countries with strong enforcement capacity (Singapore, Hong Kong, Germany) have made significant pangolin seizures and prosecuted traffickers. Countries with weak enforcement infrastructure or high levels of official corruption have seen CITES protections fail to materially reduce trafficking through their territories.

Seizure Data: The Evidence Base

The TRAFFIC organisation maintains the most comprehensive publicly available database of pangolin seizures, drawing on reports from customs authorities, police, courts, and media sources in over 150 countries. Their analyses provide the clearest picture of trafficking trends available, though the data underrepresents actual trade due to the limitations of enforcement and reporting.

Key findings from TRAFFIC and UNODC analyses include: the number of large seizures (over 1 tonne of scales or more than 100 individuals) has increased every year since 2012; the shift from Asian to African source species is clearly documented from 2014 onward; Nigeria appears in the chain of custody of the majority of large seizures destined for Asia; and seizure rates in Asia, particularly in Singapore and Hong Kong, have increased as a result of improved customs scanning technology and better intelligence sharing between enforcement agencies.

The UNODC World Wildlife Crime Report, published most recently in 2024, identified pangolin trafficking as one of the highest-value wildlife crime categories globally, second only to timber trafficking in terms of estimated annual value. The estimated annual value of pangolin trafficking is calculated in the hundreds of millions of US dollars, making it highly profitable relative to the risks imposed by enforcement in most jurisdictions.

South African Law: Legal Penalties

In South Africa, pangolin protection falls primarily under the National Environmental Management: Biodiversity Act 10 of 2004 (NEMBA) and the regulations made under it. The ground pangolin (Smutsia temminckii) is listed as an endangered species under the Threatened or Protected Species (TOPS) Regulations. Under TOPS, it is a criminal offence to hunt, capture, disturb, possess, sell, buy, donate, receive, import, export, or transport a pangolin or any derivative (including scales) without a permit issued by the relevant provincial nature conservation authority.

Penalties for NEMBA violations involving Appendix I listed species can include fines of up to R10 million (approximately USD 540,000 at recent exchange rates) and imprisonment of up to ten years, or both. In practice, sentences imposed by South African courts have often been considerably lower than the maximum, reflecting the general difficulty of prosecuting wildlife crime and the relative novelty of high-value pangolin cases before the courts. However, several significant prosecutions in the past decade have resulted in multi-year prison sentences for individuals convicted of pangolin trafficking, and the judiciary has shown increasing willingness to treat pangolin crime as serious organised crime rather than minor regulatory infringement.

The Hawks (Directorate for Priority Crime Investigation) and the South African Police Service's Environmental Crimes Unit work with the Department of Forestry, Fisheries and the Environment and provincial conservation authorities to investigate pangolin trafficking cases. NGO partnerships — particularly with organisations such as the Pangolin Crisis Fund and African Wildlife Foundation — provide intelligence, field support, and resources that augment official enforcement capacity.

Conservation Organisations Fighting Trafficking

A network of NGOs, research institutions, and intergovernmental bodies works to address pangolin trafficking at various points in the supply chain. TRAFFIC focuses on monitoring and research, producing intelligence that informs law enforcement and policy. WildAid and Education for Nature Vietnam (ENV) focus on demand reduction through consumer campaigns, working with celebrities and media in China and Vietnam to shift social norms around pangolin consumption.

The Pangolin Crisis Fund, established in 2020, provides rapid-response funding to conservation organisations working in countries where pangolin populations face acute threats. The African Pangolin Working Group coordinates research and conservation efforts across the range of African pangolin species, maintaining a rescue and rehabilitation network for confiscated pangolins. Save Pangolins operates public awareness and education programs targeted at international audiences.

The Environmental Investigation Agency (EIA) conducts undercover investigations of trafficking networks, gathering evidence that can be used in criminal prosecutions and delivered to CITES enforcement bodies. The EIA's investigations have been instrumental in exposing specific trafficking routes and identifying criminal actors who have subsequently been prosecuted. At the intergovernmental level, INTERPOL's Environment Crime unit coordinates cross-border intelligence sharing and joint operations, including Operation Thunderstorm and Operation Thunder, which have resulted in pangolin seizures across multiple continents simultaneously.

What Consumers Can Do

The most direct action any individual can take is to refuse to purchase, consume, or gift products containing pangolin scales or meat. This applies regardless of the context — whether offered in a restaurant, a pharmacy, or through an online market. If you encounter pangolin products being sold, report the seller to local wildlife law enforcement, TRAFFIC's wildlife crime tipline, or the relevant national authority.

Consumers with influence in Chinese or Vietnamese communities can make a significant difference by engaging in conversations about the lack of medicinal value in pangolin scales and the social and environmental cost of the trade. Research by demand-reduction NGOs has consistently found that personal conversations with trusted individuals are more effective in changing consumption behaviour than advertising campaigns.

Supporting organisations that work directly on pangolin conservation and anti-trafficking — through donations, volunteering, or amplifying their work — provides resources that are chronically scarce relative to the scale of the problem. Pangolin conservation is underfunded compared to high-profile species like elephants, rhinoceroses, and lions, and increased public attention and financial support directly enable field work, rehabilitation of seized animals, and advocacy for stronger enforcement.
