Import Tips
• Verify particle size and stability to confirm colloidal nature; non-colloidal gold compounds fall under different headings
• Provide certificates of analysis showing precious metal content and dispersion for customs valuation
• Ensure proper labeling as hazardous if concentrated to comply with DOT and EPA import regulations
