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
