Products classified under HTS 7104.29.00.00
Synthetic Alexandrite Rough
Color-change synthetic chrysoberyl (BeAl2O4) grown via Czochralski method, roughly shaped boules. Classified HTS 7104.29.00.00 as other synthetic precious stones, unworked beyond sawing, not strung/set. Rare color-change property but synthetic per chapter rules.
YAG Synthetic Garnet Rough
Yttrium aluminum garnet (YAG) synthetic crystals for laser rods/oscillators, roughly shaped rods. HTS 7104.29.00.00 covers synthetic semiprecious garnets, simply worked, industrial optics grade.
Synthetic Rutile Rough
Synthetic titanium dioxide (rutile) crystals for optical polarizers, roughly sawn. HTS 7104.29.00.00 as synthetic semiprecious stones.
Grown Synthetic Aquamarine Rough
Hydrothermal synthetic beryl (aquamarine color), rough cleaved crystals.
Synthetic Topaz Rough
Flux-grown synthetic aluminum fluorosilicate, rough boules.
Synthetic Sapphire Rough Crystal
Roughly shaped synthetic corundum crystals produced via the Verneuil flame fusion process, used primarily for watch bearings, laser components, and gem cutting. Classified under HTS 7104.29.00.00 as synthetic precious stones (corundum), unworked beyond simple sawing or rough shaping, not strung, mounted, or set. Meets chapter definitions for synthetic precious stones whether worked or graded but excluding strung or set forms.
Synthetic Ruby Boule
Cylindrical synthetic ruby boule grown by Verneuil method, roughly shaped with minimal faceting removal, destined for optical windows and laser rods. Falls under HTS 7104.29.00.00 as other synthetic precious stones (corundum), simply sawn or roughly shaped but not mounted/set. Excludes alloys or clad materials per chapter note 7.
Cubic Zirconia Rough Preforms
Skull-melted synthetic cubic zirconia (ZrO2) crystals, roughly sawn into octahedral preforms for gemstone cutting. HTS 7104.29.00.00 covers other synthetic semiprecious stones, unworked or simply shaped, not set/strung. Popular diamond simulant but chemically distinct per chapter definitions.
Synthetic Spinel Rough Crystals
Flame-fusion synthetic spinel (MgAl2O4) rough crystals in blue/pink shades, simply sawn for further processing into gems or optics. Under HTS 7104.29.00.00 as other synthetic semiprecious stones, roughly shaped but not graded for retail or set. Chapter notes exclude Chapter 96 imitation materials.
Hydrothermal Synthetic Emerald Rough
Hydrothermally grown synthetic beryl (emerald) crystals, roughly shaped via cleaving, replicating natural inclusions for jewelry cutters. HTS 7104.29.00.00 for synthetic precious stones, simply sawn/roughly shaped, excluding mounted forms per note 10. Key for flux vs. hydrothermal distinction in docs.
