3D printing, a technology only a few decades old, has progressed in quality and affordability. It has moved from the realm of industrial prototype, through cutting-edge design and technology, to finally end up in the homes of hobbyists and enthusiasts. This welcome and useful process has delivered new and affordable solutions to a range of subjects and fields, and has changed the shape of manufacturing from large factories to small bespoke businesses. However, this innovation has also developed a darker side and has been adopted by those with criminal intent, including for the manufacture of firearms. While converted or backstreet guns are not a new phenomenon, the advent of 3D printing has extended the range of people able to obtain a firearm to include those with no practical skills or tools or indeed any criminal connections. In the space of little over a decade, the concept of homemade guns using 3D printing techniques has evolved from a simple yet effective one-shot pistol to a semi automatic hybrid rifle. These firearms have made their way into the hands of criminals and extremists with menacing intent. They have also featured in high-profile shootings with fatal consequences. It is important to acknowledge that this nascent method of firearm production is developing at a rapid speed. Authorities and law enforcement agencies are recognising the growing threat that these firearms pose, and are adapting their understanding, approach and expertise. In addition, legislators around the world are beginning to adapt their laws to address this emerging threat. In the EU, possession of a 3D-printed firearm is an offence, but not possession of, publicity for or distribution of digital blueprints or hard copies. IN THIS BRIEFING • Introduction • 3D printing • Craft production of privately-made firearms . • Progression of 3D printed firearms • Users of 3D printed firearms • Addressing the issue

The proliferation of counterfeits for sale on e-commerce sites has created new and more dangerous challenges to brand owners than counterfeits sold through brick and mortar establishments. Most brand owners are currently focusing their efforts on simplifying and streamlining Notice and Takedown (“NTD”) procedures set up by ecommerce platforms to remove illegal listings. The shortcomings of these efforts are that NTDs do not directly reach the counterfeiter who remains free to conduct its illegal activities with impunity and that NTDs do not prevent delisted counterfeiters from reappearing in short order under a new fictitious name and identity. Brand owners should seek to induce China to rigorously enforce its recently enacted Electronic Commerce Law (“ECL”), which was designed by China’s lawmakers to create a “choke point” that excludes counterfeiters and other unscrupulous merchants from gaining access to online accounts. The ECL requires multiple layers of government review and approval that were designed so that they can be satisfied only by legitimate and economically viable business entities. To date, e-commerce sites in China do not strictly comply with the ECL, and U.S.-based ecommerce sites do not require any compliance whatsoever with the ECL. Rigorous enforcement of the ECL should result in preventing counterfeiters from gaining access to e-commerce sites based in China and the United States and should lead to a decrease in sales of counterfeits on the internet.

An immense supply chain pipeline constantly funnels millions of counterfeit goods from Alibaba’s e-commerce sites in China to third party sellers who sell these goods on Amazon to U.S. consumers. Amazon has acknowledged that it has a problem with counterfeits on its e-commerce sites, but its current responses to counterfeiting are primarily performative and intended to pacify disgruntled brand owners and frustrated consumers. Amazon’s responses will likely have little or no effect on counterfeits on its websites. This Article sets forth a direct and straightforward method for shutting down or seriously disrupting this pipeline based on using China’s existing laws. This method involves using verification methods required by China’s laws to ensure that only lawful and legitimate businesses, not counterfeiters, can open online accounts on Alibaba and other Chinese e-commerce platforms. Unless these steps are taken, counterfeits sold on Amazon and other e-commerce platforms will likely continue to plague brand owners, consumers, and the general public in the United States for the foreseeable future.

SITUATION UPDATE: LATIN AMERICA

Based on UN Comtrade data, reported global small arms and light weapons (hereafter ‘small arms’) exports rose sharply from USD 5 billion in 2019 to USD 9.2 billion in 2024. Consistent with previous trade updates, ammunition remains the most traded weapon category, accounting for 35% of the value of reported global imports for the period 2019–24, followed by sporting and hunting shotguns and rifles (21%), and pistols and revolvers (18%).

The Authorized Trade in Small Arms: Latin America from a Global Perspective—a Situation Update from the Mapping the Transnational Circulation and Control of Small Arms in Latin America project—examines the global authorized trade in small arms between 2019 and 2024, with a particular focus on trends in Latin America. It finds the region to be a comparatively small player in the global authorized small arms trade, accounting for 2.8% of global small arms imports and 6.3% of exports. Yet military firearms represented about 10% of all Latin American small arms imports during this period—almost double the global average of 5.6%.

The Situation Update also identifies a significant increase in European—and in particular Eastern European—imports during this period, which seem to have fuelled the growing trade. Indeed, European imports accounted for 40% of all reported global imports in 2024, while the value of Eastern European imports multiplied by more than ten between 2019 and 2024.
