Tariff refunds on horizon for US diamond importers after court victory
Diamond importers in the United States may receive tariff refunds after a ruling by the U.S. Court of International Trade overturning duties under the International Emergency Economic Powers Act.
In a major win for diamond traders, US importers stand to reclaim tariffs paid under the now-defunct IEEPA regime, following a pivotal U.S. Court of International Trade ruling on March 4. The decision mandates U.S. Customs and Border Protection (CBP) to refund all IEEPA duties collected before the Supreme Court’s February 20 declaration of their illegality—complete with interest.
- Streamlined Refund Process: Importers can apply via CBP’s ACE Portal starting mid-April, uploading summaries of IEEPA duties paid. Described as efficient, it targets diamond entries amid broader refunds for 53 million across 330,000 importers in all sectors.
- CBP Caution on Delays: Expect significant processing backlogs due to the massive volume, though diamonds form a fraction—traders urged to prepare documentation early for smoother navigation.
- Unaffected New Tariffs: The ruling spares President Trump’s fresh 10% reciprocal tariffs, imposed post-ruling. Analysts predict a hike to the 15% legal cap as early as this week, signaling ongoing trade tensions.
- Backstory on IEEPA Tariffs: Trump’s original levies, enacted under the 1977 International Emergency Economic Powers Act after declaring a “national emergency” last April, aimed to counter foreign practices but were struck down for overreach.
Strategic Implications
The combination of refunds due and ongoing tariffs creates a nuanced strategic environment for diamond importers:
- Short-term: Cash flow relief from IEEPA refunds (when received) may offset some of the ongoing tariff burden
- Pricing: Forward contracts and retail pricing must account for the new (and potentially higher) tariff baseline
- Sourcing: Country-of-origin strategies may need to be reviewed if tariff rates vary by origin under the new regime
- Compliance: Accurate record-keeping for the refund process is essential and should not be deferred
This development offers financial relief to cash-strapped diamond firms, potentially injecting liquidity into a volatile market. However, persistent tariffs underscore the need for vigilant compliance and lobbying. Importers should monitor CBP updates closely.

CIBJO Backs ‘synthetic’ As Sole Label For Man-Made Diamonds
CIBJO’s Laboratory-Grown Diamond Committee, Told Delegates That “Synthetic” Remains The Primary Term Recognized By Consumers, Despite A Formal Push From The Sector’s Steering Committee To Defer The Ruling and Authorize “Laboratory-Grown.”
The World Jewellery Confederation (CIBJO) has recommended “synthetic” as the only acceptable descriptor for non-mined diamonds, rejecting calls from trade leaders to permit the term “laboratory-grown,” the organization said on Monday.
The decision, finalized at the closing session of the 2026 CIBJO Congress, deepens a global divide over gemstone terminology at a time when manufactured stones are rapidly eroding the market share and pricing power of mined gems.
CIBJO’s Laboratory-Grown Diamond Committee, told delegates that “synthetic” remains the primary term recognized by consumers, despite a formal push from the sector’s steering committee to defer the ruling and authorize “laboratory-grown.”
CIBJO’s move aligns with a growing regulatory push in several major markets. France restricted terminology to “synthetic” in 2024, Russia followed suit in June, and the London Diamond Bourse endorsed the single descriptor on Sunday. In May, the African Diamond Producers Association also tightened descriptor rules to shield the natural diamond trade.
In contrast, regulators and retailers in the United States and India have favored consumer-friendly phrases such as “lab-grown” or “laboratory-grown.” The commercial stakes are particularly high in the U.S., where synthetic stones now account for more than half of all engagement ring sales by volume, applying severe downward price pressure on natural rough and polished stones.
CIBJO, which began moving to strike “lab-grown” from its influential Diamond Blue Book standards last year, warned that the diverging legal frameworks are leaving the global market increasingly fragmented.
