U.S. imports of nonindustrial diamonds, worked (polished or drilled) (HS 710239) totaled $397.6M in July 2026, traded with 59 countries.
Importers of Nonindustrial Diamonds, Worked (Polished or Drilled) paid $5.4M in duties in July 2026 — an effective duty rate of 10% on $53.6M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataPolished, drilled, and otherwise worked gem-quality diamonds — the finished loose stones that feed the jewelry and investment markets — are split at the US 10-digit level by carat weight: stones of 0.5 carats or less (7102390010) and stones exceeding 0.5 carats (7102390050), a distinction that reflects significant differences in per-unit value and customs valuation scrutiny. India dominates US imports under this heading, driven by Surat's position as the world's largest diamond polishing center; Belgium and Israel are also major sources. The weight-based split means that mixed parcels containing stones both above and below the 0.5-carat threshold must be separated and declared on distinct tariff lines. High-value individual stones may attract enhanced CBP appraisement review.

The 0.5-carat breakpoint reflects a commercially meaningful size distinction: melee diamonds (typically under 0.5 ct) are traded in bulk parcels and priced per carat as a lot, while larger stones are individually valued and priced. The split allows CBP to apply different valuation scrutiny appropriate to each segment and aligns with industry practice for invoicing and grading.
CBP generally applies transaction value for polished diamonds, but given the high per-unit value and the potential for related-party transactions between diamond trading houses, importers should be prepared to support declared values with independent appraisals, Rapaport price list references, or GIA/IGI grading certificates. CBP may refer high-value shipments for formal appraisement if the declared value appears inconsistent with market benchmarks.
