Import Tips
• Provide manufacturing process certification proving artificial graphite base with silicon doping to avoid natural graphite subheadings
• Declare exact silicon percentage (typically 5-20%) as it determines anode performance and classification accuracy
• Watch for anti-dumping duties on graphite from certain origins; check Commerce Department updates
