Customs Indefinitely Postpones Requirement to Disclose Country of Mining
Originally slated to take effect in April, official U.S. Customs and Border Protection documents now show the implementation date as “TBD.”

While CBP’s earlier announcement of the new requirement stated it would take effect in April, a newer Automated Customs Environment (ACE) schedule has the enactment date as “TBD,” or to be determined.
The new requirement is an addition to the regulations already in place, which require importers to self-certify that the diamonds they are importing into the U.S. are not from Russia.
If and when the new country of mining requirement takes effect, a new field for “country of mining” will be added to the Automated Customs Environment (ACE) manifest that importers must fill out, along with an option to upload supporting documentation.
Jewelers of America said it recently updated its members on the current CBP requirements for diamond imports, including information about the new “country of mining” requirement that was expected in April.
The organization sent a follow-up note over the weekend notifying members of the delay in implementation.
“Given how quickly the situation can change—one way or another—we remain engaged and responsive to our members as questions come up, but our overriding guidance from the start of the war has been that Jewelers of America members should not source diamonds that emanate from Russia, regardless of where they are cut and polished, and [be] proactive by communicating with suppliers and conducting due diligence of their supply chains,” the organization said in a statement.
“We want members to be prepared, regardless of specific regulations that could be in the pipeline.”
Last week, the EU announced that it now will require diamond importers to provide information about where exactly their diamonds were mined.
As part of its 16th package of sanctions against Russia, the EU said that, as of March 1, importers will be required to provide a Kimberley Process certificate that states the exact country of origin for all the rough diamonds in each shipment.
The EU also postponed implementation of a system for tracking rough diamonds from mine to market, setting a new deadline of Jan. 1, 2026, citing the need for more time to refine a system.
The G-7 announced in December 2023 that member countries that are “major” importers of rough diamonds need to establish a “robust traceability-based verification and certification mechanism” for tracking diamonds through the supply chain.
The G-7 originally set a deadline of Sept. 1, 2024, for the creation and implementation of such a system, a deadline the EU has now pushed back twice, first to March 1, 2025, and now to the beginning of 2026.
