An Indian company shipped $1.4 million worth of an explosive compound with military uses to Russia in December, according to Indian customs data, despite U.S. threats to impose sanctions on any entity supporting Russia¡¯s Ukraine war effort.

One of the Russian companies listed as receiving the compound, known as HMX or octogen, is the explosives manufacturer Promsintez, which an official at Ukraine¡¯s SBU security service said has ties to Moscow¡¯s military. The official said that Ukraine launched a drone attack in April against a Promsintez-owned factory.

The other Russian company is a subsidiary of Spanish explosives manufacturer Maxam, which is itself controlled by New York-based private equity firm Rhone Capital.
