Due to new regulations announced by U.S. Customs and Border Patrol on March 1, 2024 any diamonds 1.00 carat or greater shipped internationally to the United States are required to have a signed and dated letter on your company letterhead with this specific language for entry:
“I certify that the nonindustrial diamonds in this shipment were not mined, extracted, produced, or manufactured wholly or in part in the Russian Federation, notwithstanding whether such diamonds have been substantially transformed into other products outside of the Russian Federation.”
Please work directly with your courier to ensure you are complying with these new requirements for import to the United States. Click here for more information regarding these updated regulations and please note that these are subject to change.
