Import Tips
• Use ventilated containers; dust form heightens fugitive emission risks during customs inspection
• Cross-check against RCRA waste codes; many ports require pre-clearance for toxic metal dusts
• Document particle size if relevant, distinguishing from 'coarse' ores in related statistical notes
