HS Code 71.04 – Stones; synthetic or reconstructed precious or semi-precious, whether or not worked or graded but not strung, mounted or set; ungraded synthetic or reconstructed precious or semi-precious stones, temporarily strung for convenience of transport

HS code 7104 is a 4-digit heading in the Harmonized System that covers: Stones; synthetic or reconstructed precious or semi-precious, whether or not worked or graded but not strung, mounted or set; ungraded synthetic or reconstructed precious or semi-precious stones, temporarily strung for convenience of transport. HS Code 7104 encompasses synthetic or reconstructed precious or semi-precious stones. This crucial heading covers these stones whether they are unworked, worked, or graded, but explicitly excludes those that are already strung, mounted, or set as finished jewelry or articles. It also includes ungraded synthetic or reconstructed stones that are temporarily strung solely for the convenience of transport, ensuring they are not considered finished articles. The scope of 7104 is focused on the raw material or semi-processed forms of man-made gemstones, crucial for industries ranging from high-end jewelry manufacturing to industrial applications requiring their unique properties. This classification is vital for trade compliance as it distinguishes these materials from natural stones (7103), finished jewelry (7113, 7116), or imitation jewelry (7117), each carrying different tariff rates, import regulations, and statistical reporting requirements. By accurately classifying under 7104, businesses ensure correct duty assessment and avoid potential penalties. Historically, the rise of synthetic gemstones has created a distinct market, and this heading accurately reflects their separate identity in global trade. As part of Section XIV, which covers natural or cultured pearls, precious or semi-precious stones, and precious metals, 7104 plays a significant role in categorizing the manufactured counterparts of natural gems, acknowledging their economic importance and technological advancements in material science. Understanding its boundaries is key for importers, exporters, and customs brokers navigating the complex world of gemstones.

Rough synthetic diamonds, faceted lab-grown rubies, reconstructed emeralds (unmounted), synthetic sapphires (cut but unset), cubic zirconia (CZ) stones, moissanite gemstones, synthetic alexandrite crystals, synthetic spinel (loose), synthetic quartz (faceted), reconstructed turquoise cabochons, synthetic opals (unshaped), cut synthetic garnet, graded synthetic amethysts (loose), temporarily strung synthetic pearls (for transport), bulk parcels of assorted synthetic gemstones, polished synthetic topaz, synthetic aquamarine (unmounted), lab-created morganite, synthetic peridot (loose), synthetic bismuth crystals, synthetic chrysoberyl, synthetic tanzanite, synthetic tourmaline, synthetic moonstone, synthetic jade.

A common misclassification error involves confusing products under 7104 with natural stones in 7103. The key differentiator is the origin: 7104 is exclusively for synthetic or reconstructed stones, while 7103 is for natural ones. Misclassifying can lead to incorrect duty rates and origin declarations. Another frequent mistake is classifying finished jewelry containing synthetic stones under 7104. If the stones are already strung as necklaces or bracelets, or set in rings or pendants, they typically fall under 7116 (Articles of natural or cultured pearls, precious or semi-precious stones) or 7117 (Imitation jewelry) if set in base metal. 7104 strictly applies to loose, unmounted, or temporarily strung stones. Traders must meticulously verify the manufacturing process and the degree of finishing.

In 2025, the top exporters of HS code 7104 in UN Comtrade data were India ($1.3B, 33% of world exports), Hong Kong ($930M) and China ($531M). World exports came to about $3.9B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

In 2025, the top importers of HS code 7104 in UN Comtrade data were India ($1.1B, 28% of world imports), Hong Kong ($726M) and the United States ($602M). World imports came to about $4.0B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

HS code 7104 is a 4-digit heading under Chapter 71 of the Harmonized System. The first 2 digits (71) identify the chapter, and digits 3-4 (04) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
