Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If faceted/polished for jewelry use
Advanced working beyond rough shaping classifies as 'precious stone articles' under 7116.
If natural mineral zircon, not synthetic
Natural zirconium silicates fall in Chapter 25; synthetic ZrO2 stays in Chapter 71.
If high-purity polycrystalline for ceramic applications
Industrial ceramic porcelain shifts to Chapter 69 based on end-use.

Import Tips & Compliance
ā¢ Disclose chemical composition (ZrO2 stabilized with Y2O3) in entry docs to confirm semiprecious stone status
ā¢ Avoid retail packaging; bulk import prevents reclassification as finished jewelry
