Imports of certain diamond compacts blocked

If you import or resell these specified products, those imports are blocked under the Commission's order issued December 4, 2025.
U.S. seller ordered to stop sales
The Commission issued a Cease and Desist Order (CDO) against SF Diamond USA, Inc., requiring the company to stop selling in the United States certain polycrystalline diamond compacts and articles that infringe claims 1, 2, 11, 15, and 21 of U.S. Patent No. 10,508,502. The CDO was part of the Commission's determination delivered on December 4, 2025.
Zero bond during Presidential review
For the period of Presidential review, the Commission set the required bond at zero percent (0%) of the entered value for the excluded infringing products. That means importers of those excluded products are not required to post a bond during the Presidential review period.
