Import Tips
• Document gold coating purity and application method (e.g
• PVD) as precious metal content may trigger additional declarations
• Test for powder form compliance; particles >0.5mm risk reclassification away from subheading 7106.10 definition
• Pair with end-use statements for electronics to distinguish from abrasive applications that could shift headings
