Import Tips
• Submit sieve analysis and zinc purity assays; customs often tests samples for note (c) compliance
• Avoid generic 'zinc powder' labeling—specify 'zinc dust' with production method to prevent reclassification
• For hazardous material declarations, classify as UN 1436 to comply with DOT/IMDG shipping rules
