Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing ≤97% calcium fluoride
Weight-based purity directly dictates fluorspar subheading selection.
If primarily natural borates instead of fluorspar
Borates have separate heading; composition determines primary classification.
If pre-mixed into ceramic refractory compositions
Prepared refractory mixtures shift to Chapter 69 as worked ceramic goods.

Import Tips & Compliance
• Certify granule uniformity and purity; variance can lead to purity disputes
• Include end-use statements for ceramics to support valuation claims
• Screen for silica content which could trigger alternative mineral classifications
