Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If punched, cut, or fabricated into plates/ strips
Worked mica in plates, sheets, or strips after splitting enters Chapter 68.
If for unsplit crude phlogopite blocks
Unprocessed crude mica before rifting or splitting remains in the crude category.
If imported as part of electrical insulators
Assembled into finished electrical components shifts to Chapter 85 machinery articles.

Import Tips & Compliance
• Provide mineral composition certificates confirming phlogopite vs. muscovite to support valuation
• Ensure packaging prevents breakage—damaged splittings may classify as mica waste (2525.20)
• Avoid mixing with powders; pure splittings prevent misclassification as worked products
