Import Tips
• Provide certificates of analysis (COA) proving >90% MnO2 content to prevent reclassification as lower-grade materials
• Label containers with UN 1479 (Oxidizing solid, n.o.s.) for hazardous goods handling
• Check for anti-dumping duties on manganese dioxide from certain origins like China
