Subheadings
Products classified under Tariff item 7104.29.00
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.
Grown Synthetic Aquamarine Rough
Grown synthetic aquamarine rough consists of hydrothermal synthetic beryl crystals in aquamarine color, presented as rough cleaved crystals. They are unworked or simply shaped, not strung, mounted, or set, and are classified under tariff item 7104.29.00 as other synthetic precious stones.
Hydrothermal Synthetic Emerald Rough
Hydrothermal synthetic emerald rough consists of synthetic beryl crystals grown in a hydrothermal solution and roughly shaped by cleaving. They replicate natural inclusions and are intended for jewelry cutters, but are not strung, mounted, or set, so they qualify as other synthetic precious stones under tariff item 7104.29.00.
Synthetic Alexandrite Rough
Synthetic alexandrite rough is color-change synthetic chrysoberyl grown by the Czochralski method, presented as roughly shaped boules. These are unworked beyond sawing, not strung or set, and fall under tariff item 7104.29.00 as other synthetic precious stones.
Synthetic Ruby Boule
Synthetic ruby boules are cylindrical synthetic corundum crystals grown by the Verneuil method, roughly shaped with minimal faceting removal. They are destined for optical windows and laser rods, but as unworked or simply shaped synthetic precious stones, they fall under tariff item 7104.29.00.
Synthetic Rutile Rough
Synthetic rutile rough consists of synthetic titanium dioxide crystals for optical polarizers, roughly sawn. They are unworked or simply shaped, not strung, mounted, or set, and are classified under tariff item 7104.29.00 as other synthetic semi-precious stones.
Synthetic Sapphire Rough Crystal
Synthetic sapphire rough crystals are roughly shaped synthetic corundum crystals produced via the Verneuil flame fusion process. They are used for watch bearings, laser components, and gem cutting, but as unworked or simply shaped synthetic precious stones, they fall under tariff item 7104.29.00.
Synthetic Spinel Rough Crystals
Synthetic spinel rough crystals are flame-fusion synthetic magnesium aluminate crystals in blue and pink shades, simply sawn for further processing into gems or optics. They are unworked or roughly shaped, not strung, mounted, or set, and fall under tariff item 7104.29.00 as other synthetic semi-precious stones.
Synthetic Topaz Rough
Synthetic topaz rough consists of flux-grown synthetic aluminum fluorosilicate, presented as rough boules. They are unworked or simply shaped, not strung, mounted, or set, and are classified under tariff item 7104.29.00 as other synthetic semi-precious stones.
YAG Synthetic Garnet Rough
YAG synthetic garnet rough consists of yttrium aluminum garnet synthetic crystals for laser rods and oscillators, presented as roughly shaped rods. They are unworked or simply shaped, not strung, mounted, or set, and fall under tariff item 7104.29.00 as other synthetic semi-precious stones.
