HS Code 7105.10 – Stones; precious and semi-precious, dust and powder, of diamonds
HS code 7105.10 is the 6-digit subheading for stones, precious and semi-precious, dust and powder, of diamonds. It is used for industrial diamond powder, diamond abrasive grit, micron diamond powder, synthetic diamond dust and diamond polishing compound.
What HS 7105.10 covers
This code covers industrial diamond dust and powder, crucial for abrasive applications, cutting tools, and polishing. It's a high-value, specialized commodity in international trade, primarily imported by manufacturing hubs and countries with advanced industrial sectors. Exporters are typically countries with significant diamond mining operations or those specializing in diamond processing. Key things to know include the importance of particle size and purity for specific industrial uses, the role of synthetic diamonds in this category, and the stringent quality control required. The trade often involves specialized distributors and manufacturers rather than direct consumers, reflecting its industrial utility. The global demand is driven by sectors like automotive, aerospace, electronics, and construction, where precision grinding and cutting are essential. This category highlights the industrial utility of diamonds beyond their gemological value, emphasizing their role as a critical material in modern manufacturing processes.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
