Import Tips

• Provide electrolytic production process certificates to distinguish from natural MnO2 and support 'chemically defined' status

• Comply with TSCA import requirements for new chemical substances if purity exceeds standard battery grades

• Avoid common pitfalls by ensuring particle size specs are documented to prevent reclassification as a micronized preparation
