This bill creates a comprehensive sanctions program targeting Russia's 'shadow fleet'—a network of foreign ships used to transport Russian oil, weapons, and other goods while evading international sanctions. The law aims to cut off Russia's ability to sell oil above agreed price limits and to circumvent existing trade restrictions.

The bill targets three main groups: ships involved in the shadow fleet, companies and individuals who support these ships (like insurance providers and port operators), and foreign entities helping Russia's energy projects. The government can sanction vessels showing suspicious behavior like turning off tracking systems, refusing to take on pilots, or lacking proper insurance. It also targets ports in China and India that accept sanctioned Russian oil, and foreign companies selling military equipment or technology to Russia.

The law requires extensive reporting to Congress on Russian oil exports, China's role in helping Russia evade sanctions, and efforts to enforce the oil price cap. It authorizes $200 million to support Ukraine and Eastern European allies, and funds to strengthen the government's sanctions enforcement capabilities. The bill also strengthens existing sanctions on Russian energy projects and pipelines, and requires the government to monitor whether Russia is escalating military activities in the Baltic Sea to interfere with sanctions enforcement.

For everyday people, this bill mainly affects international shipping, insurance, and energy companies that do business with Russia or handle Russian oil. It could influence global oil prices and energy markets, and aims to reduce Russia's war-making capacity by limiting its oil revenues.
