Since January 2008, Singapore’s Strategic Goods Control List has expanded to incorporate all the items listed under the four multilateral export control regimes, namely the Missile Technology Control Regime (MTCR), Australia Group (AG), Nuclear Suppliers Group (NSG) and the Wassenaar Arrangement (WA). Lists are quite easy to locate, and they are similar to the EU and US build-up.
Singapore’s Strategic Goods (Control) Act (SGCA) and Strategic Goods (Control) Regulations 2004 are the legal basis for the Strategic Goods Control List under Singapore Customs. Since then a number of amendments have arrived, which you may access here.
The Strategic Goods (Control) Act controls export, re-export, transit and brokering of goods and technology from Singapore. While the term “brokering” is unknown or ignored in many European countries, Singapore Customs has put additional focus on this, and transfer of intangible technology. Singapore Customs has published the Strategic Trade Scheme (STS) Handbook, which provides an overview of the controls.
Singapore Customs lists United Nations Security Council (UNSC) Sanctions, and it provides an overview of other unilateral sanctions including EU, US and Japanese sanctions. As far as I understand, The Singapore Government may actually require that all sanctions (i.e., UN, EU, US and Japanese) are complied with. A strong indication that this is true is a recent case involving extradition of four Singaporeans who have been charged in the United States with violations of U.S. laws relating to fraud involving the unlawful export from the United States of military antennas and radio frequency modules.
Singapore Customs has produced a quite good presentation of the export control processes, which is available here.
