HS Code 71.05 – Dust and powder of natural or synthetic precious or semi-precious stone

HS code 7105 is a 4-digit heading in the Harmonized System that covers: Dust and powder of natural or synthetic precious or semi-precious stone. HS Code 7105 is specifically dedicated to the classification of dust and powder derived from natural or synthetic precious or semi-precious stones. This heading captures the most fragmented forms of these valuable materials, distinguishing them from their whole or semi-manufactured counterparts. The scope includes diamond dust, ruby powder, sapphire powder, and similar finely ground materials, regardless of whether they originate from natural geological formations or from lab-grown synthetics. The primary application for products under 7105 is typically industrial, leveraging the extreme hardness and abrasive properties of these materials. They are indispensable in manufacturing cutting tools, polishing compounds, precision abrasives, specialized coatings, and even advanced electronics. This classification is critical for trade compliance because it segregates these industrial raw materials from larger, more valuable gemstones (7103, 7104) and from other industrial powders that do not originate from precious or semi-precious stones. Accurate classification ensures correct duty assessment, adherence to specific environmental and safety regulations for fine powders, and proper statistical tracking of these niche but economically significant commodities. As part of Section XIV, which covers precious materials, 7105 highlights the diverse utility of precious and semi-precious stones beyond their ornamental value, emphasizing their role in high-tech and manufacturing sectors globally.

Industrial diamond powder (synthetic), natural diamond dust (polishing grade), ruby powder (abrasive), sapphire powder (for coatings), emerald powder (specialty abrasive), cubic zirconia dust, moissanite powder (industrial), garnet abrasive powder, silicon carbide powder (if derived from precious stone synthesis), polishing compounds containing diamond dust, industrial-grade sapphire grit, fine natural opal powder, reconstructed turquoise powder, synthetic quartz powder (for optics), industrial-grade diamond grit, boron nitride powder (cubic form), nano-diamond powder, micro-diamond powder, polishing pastes with diamond, dental abrasive powder, ceramic coating powders, high-purity sapphire powder, synthetic ruby grit, diamond lapping compounds, diamond slurry.

Misclassifications often occur when traders fail to distinguish the origin or specific form of the powder. Some industrial carbides or abrasive powders, such as those in Chapter 28 (e.g., silicon carbide or boron carbide under 2849), may be confused with 7105. The key distinction is that 7105 specifically covers dust and powder *of* natural or synthetic precious/semi-precious stones, not general industrial abrasives. Another mistake is classifying prepared pigments or polishing preparations containing these powders under 7105. If the powder is mixed with binders, solvents, or other substances to form a compound, it may fall under headings like 3207 (Prepared pigments, opacifiers, enamels and glazes) or other chemical preparations. 7105 is strictly for the pure dust or powder form. Ensure the material is not chemically altered or compounded.

In 2025, the top exporters of HS code 7105 in UN Comtrade data were China ($210M, 50% of world exports), the United States ($53M) and Ireland ($51M). World exports came to about $419M, 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 7105 in UN Comtrade data were South Korea ($66M, 16% of world imports), Japan ($48M) and Ireland ($40M). World imports came to about $418M, 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 7105 is a 4-digit heading under Chapter 71 of the Harmonized System. The first 2 digits (71) identify the chapter, and digits 3-4 (05) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
