Cubic Zirconia Rough Preforms
Cubic zirconia rough preforms are synthetic zirconium dioxide crystals grown by skull melting and roughly sawn into octahedral shapes for gem cutting. They are unworked or simply shaped, not strung, mounted or set, and therefore fall under tariff item 7104.29.00 as other synthetic semi-precious stones.

Import Tips & Compliance
• Ensure the cubic zirconia is not strung, mounted, or set, as that would change classification
• Keep records of the growth method (skull melting) and rough state to support the tariff classification
• Declare the value in Canadian dollars and be ready to provide a certificate of origin if claiming preferential treatment
