Importers of Nonindustrial Diamonds, Unworked or Simply Sawn, Cleaved, or Bruted paid $30K in duties in April 2026 — an effective duty rate of 10% on $298K in dutiable value, based on actual customs collections rather than the published tariff schedule. Nonindustrial Diamonds, Unworked or Simply Sawn, Cleaved, or Bruted imports of $333K in April 2026 ran 45% above the year-to-date monthly average of $229K.
Last updated: April 2026 dataGem-quality rough diamonds that have received only minimal shaping — sawing, cleaving, or bruting to establish basic form — are classified here before they enter the cutting and polishing pipeline. Botswana and South Africa lead US imports under this heading, with Namibia and Angola also significant sources, all reflecting the geographic concentration of gem-quality primary production in sub-Saharan Africa. As with all rough diamonds, Kimberley Process Certification Scheme compliance is a non-negotiable entry requirement. Importers and trading houses should be aware that the line between 'simply sawn' and more substantially worked can be a classification flashpoint, particularly for stones that have undergone preliminary shaping at the mine site.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Customs and Border Protection generally treats 'simply sawn, cleaved, or bruted' as operations that establish a basic geometric form without creating facets or a finished surface. Once a stone has been faceted, polished, or drilled — even partially — it moves into the worked nonindustrial diamond heading (710239). Importers of partially processed rough should obtain a technical description from the cutter to support the correct classification.
No. Lab-grown (synthetic) diamonds are classified under a separate chapter 71 heading for synthetic stones, not alongside natural diamonds in 710231. Importers must clearly identify whether stones are natural or synthetic on entry documentation, as misclassification between the two categories is a known area of CBP scrutiny.
