Import Tips
• Include mineral composition analysis to distinguish phlogopite from muscovite, preventing misclassification
• Declare exact thickness measurements; exceeding tolerances shifts to mica powder or waste categories
• Use moisture-proof packaging to avoid natural delamination during ocean freight, which could trigger quality disputes
