Security Tech Innovations Drive Demand Amid Rising Global Terrorism
The explosive trace detection (ETD) market is a highly specialized but growing niche market driven by increasing demand for advancements in security technology as global terrorism numbers continue to rise. The public safety, defense, critical infrastructure, border security, and transportation sectors need state-of-the-art ETD technology to confront the increasing prevalence of homemade explosives (HMEs) in the U.S. and beyond.
ETD Market Growth and Projections: Global and U.S. Markets Trend Upward

According to Yahoo Finance, the Global ETD market is projected to grow from USD 6.5B in 2023 to USD 12.1B by 2033 at a Compound Annual Growth Rate* (CAGR) of 6.41%. As technological advancements including machine learning, artificial intelligence (AI), and smart sensors enhance existing ETD systems, the ETD market is posed for continued growth over time.
North America Leads the ETD Market: Aviation Security and Border Security Insights
North America dominated the global ETD market in 2023 with a 35.6% share and is expected to continue leading the industry with its vast airport network and high volume of air traffic. Aviation security is a critical driver of the ETD market as screening systems are essential for regular Transportation Security Administration (TSA) operations. In addition to screening passengers, luggage, and cargo, North American countries need their border protections constantly maintained against smuggling of explosives and contraband. Kelly Hoggan, Chief Operating Officer of GreyScan Detection, a defense technology manufacturing and research company addressing critical gaps in current ETD systems, discusses border security and the concept of “the asymmetrical threat” in his four-part informative series published on Homeland Security Today:
It…goes without saying that if even a small number of [undocumented immigrants] are entering the country for the purpose of committing terrorism, we may find ourselves confronting a serious asymmetric threat posed by lone wolves making use of easily obtainable and mostly undetectable – at least by current systems – chemicals they would then deploy as HMEs in a variety of sizes and destructive power.
…in addition to the fact that, by definition, lone wolf terrorism is notoriously difficult to anticipate or predict…is that such bad actors present an asymmetric threat, meaning they will always attempt to pit their strengths against our weaknesses. This is especially the case when such individuals choose to utilize homemade explosives, or HMEs, made from inorganic chemicals.
Future of ETD Technology and North American Market Expansion: Innovations in Security Technology
North America is an attractive geographical target for ETD manufacturers. As the ETD market grows and invites innovations to security technologies, GreyScan Detection looks forward to fortifying public spaces and transportation ports against unpredictable HME deployments and flare attacks by terrorists.
