The World Customs Organization (WCO) successfully hosted the Programme Global Shield (PGS) Global Symposium on 20–21 May 2025 at its headquarters in Brussels. Held under the theme “Global Security through Partnership,” the two-day hybrid event gathered around 90 Customs administrations, six Regional Intelligence Liaison Offices, and representatives from international organizations, enforcement agencies, and the private sector. The Symposium served as a strategic platform for knowledge exchange, operational planning, and technological insight.
The primary focus of the event was the urgent global security challenges linked to the diversion and misuse of explosive precursors, especially in the production of Improvised Explosive Devices (IEDs) and Improvised Incendiary Devices (IIDs) including those deployed via Unmanned Aerial Vehicles (UAVs). From the proliferation of 3D-printed components and darknet trade to the weaponization of UAVs, the discussions emphasized the complexity of modern threats and the essential role of cross-sector collaboration in addressing them.
In his welcome remarks, the WCO Deputy Secretary General, Ricardo Treviño Chapa, encouraged Members to continue strengthening cooperation and information exchange among Customs and other stakeholders to enhance global supply chain security. Over two days, participants also engaged in panel discussions and technical briefings covering,
- Global data on precursor movements and seizures
- Regional and national responses, including case studies from Hong Kong, the UK, and ICAO
- Insights from partner organizations such as INTERPOL, UNODA, UNIDIR, and the NATO Counter-IED Centre of Excellence
- An update on EU Regulation 1148/2019 and its revision process
- A preview of Operation GATEWAY, the upcoming global enforcement operation scheduled for later this year
By showcasing cutting-edge intelligence, policy updates, and field-level responses, the symposium reaffirmed the WCO’s commitment to enhancing border security and safeguarding societies through innovation, vigilance, and global partnerships.
About the PGS
Launched in 2010, Programme Global Shield PGS is an unprecedented international effort to monitor the licit movement of chemicals and counter the illicit diversion and trafficking of explosive precursor chemicals and additional components used by terrorists and other illegal armed groups to manufacture IEDs.
PGS has grown into one of the WCO’s most impactful initiatives, with nearly 100 Member administrations onboard and over 4,300 customs officers trained globally. To date, PGS operations have led to the seizure of more than 580 tonnes of explosive precursor chemicals and 3.7 million explosives and components, helping to prevent the assembly of thousands of IEDs.
The Symposium also showcased the WCO’s ongoing collaboration with different United Nation bodies and highlighted the role of PGS in supporting implementation of UN Security Council Resolution 2370, aimed at preventing terrorists from acquiring weapons, explosives and components.
