On November 10, CBC Metal Network reviewed the latest snapshot of the US Department of Commerce Bureau of Industry and Security (BIS) Commerce Control List (CCL): boron and boron alloy powders fall within the scope of ECCN 1C011.b. Exports of boron powder and boron alloy powder (including high-boron ferroboron powder) with a particle size of 60 microns or less and a boron content of 85% or more require a license, with control reasons covering national security (NS), missile technology (MT), and anti-terrorism (AT). Ordinary metallurgical-grade ferroboron (boron content 14%–26%) is not controlled, and companies must self-classify item by item based on the dual parameters of particle size and boron content. Such high-purity fine-particle boron powder is mainly used for energetic additives in rocket propellants, energetic materials, and special metallurgy. In the same period, China's Ministry of Commerce's Measures for the Investigation and Enforcement of Export Controls on Dual-Use Items (Draft for Comment) is open for public comment until November 29, and boron-related export enterprises face stricter declaration and compliance system requirements. For powder traders, export compliance screening needs to be moved forward to the order-taking stage, with close attention to changes in classification boundaries and declaration procedures on both the US and Chinese sides.
