Chemical and Biological Weapons

Chemical and Biological Weapons refer to weapons that kill humans and animals or destroy crops through chemical agents or biological pathogens (such as bacteria, viruses, toxins). In foreign trade, this term is a highly sensitive dual-use item, strictly controlled by the Chemical Weapons Convention (CWC), the Biological Weapons Convention (BWC), and national export control regulations (such as China's Export Control Law and the U.S. EAR). Usage scenarios mainly involve export declarations, license applications, customs inspections, and compliance reviews. Precautions: Foreign trade practitioners must verify the end user and end use to avoid unintentional participation in proliferation; unlike conventional weapons, precursor chemicals, production equipment, and strains of bacteria and viruses for chemical and biological weapons may be disguised as civilian products, so attention must be paid to the 'dual-use items' list. Difference: Chemical weapons focus on toxic chemicals, while biological weapons focus on living microorganisms or toxins; the two are often managed together, but their legal definitions and control lists differ. Violations will result in criminal penalties, heavy fines, and international sanctions.
