U.S. exports of industrial diamonds, unworked or simply sawn, cleaved, or bruted (HS 710221) totaled $158K in July 2026.
Importers of Industrial Diamonds, Unworked or Simply Sawn, Cleaved, or Bruted paid $8K in duties in July 2026 — an effective duty rate of 6.9% on $117K in dutiable value, based on actual customs collections rather than the published tariff schedule. Industrial Diamonds, Unworked or Simply Sawn, Cleaved, or Bruted imports of $121K in July 2026 ran 13% below the year-to-date monthly average of $138K.
Last updated: July 2026 dataIndustrial-grade diamonds in their raw or minimally processed state — including miners' carbonados and other natural industrial stones — are subdivided at the US 10-digit level into carbonado miners' diamonds (7102211010), other miners' diamonds (7102211020), simply sawn/cleaved/bruted non-miners' stones (7102213000), and unworked industrial diamonds not elsewhere specified (7102214000). Botswana and South Africa are the primary sources, reflecting the concentration of natural industrial diamond production in southern Africa. These stones feed abrasive, cutting-tool, and drilling-bit manufacturing rather than jewelry supply chains, so buyers are typically industrial procurement teams rather than gem traders. The Kimberley Process Certification Scheme applies to all natural rough diamonds regardless of quality grade.

The Kimberley Process Certification Scheme applies to all rough diamonds, including industrial grades. Importers of unworked or simply processed industrial diamonds must present a valid KPCS certificate at entry, regardless of whether the stones have any gem value.
Carbonados are a specific polycrystalline form of natural industrial diamond, historically used in drill bits and heavy abrasive applications. The US tariff schedule carves them out separately (7102211010 and 7102211020) from other industrial diamonds because their physical structure and end-use profile differ from single-crystal industrial stones. Importers should confirm the mineralogical type with the supplier to select the correct 10-digit line.
