🌎 China's Export Controls Update

Recent export control announcements from China, particularly concerning materials like graphite, have focused on dual-use applications and national security. These measures primarily introduce export licensing and reporting requirements rather than altering the technical purity specifications of the materials themselves.

Therefore, as of the latest information, there is no evidence to suggest China has mandated a tightening of the purity specifications for battery-grade materials as part of these controls. The specifications continue to be driven by international battery industry standards and customer requirements.
