Iranian oil tanker activity in Malaysian waters suggests evasion of U.S. embargoes

An Iranian oil tanker, the Humanity, has been observed engaging in activities that suggest a deliberate effort to evade U.S. sanctions. The tanker sailed through the Strait of Malacca and Singapore before its automatic identification system (AIS) abruptly shut off near the coast of Malaysia. Satellite tracking data places the 330-meter vessel within Malaysia's Eastern Outer Port Limit (EOPL) in the South China Sea.

For decades, the EOPL has served as an unofficial market for Iranian, Russian, and Venezuelan oil subject to sanctions.

Maritime security experts believe the Humanity likely went 'dark' as it prepared to offload its cargo of Iranian crude oil to an intermediary vessel. This transfer is a common tactic to obscure the oil's origin, with China historically being the primary buyer of Iranian crude. The EOPL has long served as an unofficial hub for oil exports from countries under sanctions, including Iran, Russia, and Venezuela.

This operation continues despite a U.S. naval blockade of Iranian ports earlier in the year. Maritime security analysts have tracked numerous vessels disabling their AIS transponders to facilitate the sale of Iranian oil to smaller, independent Chinese refineries. These refineries are less exposed to U.S. financial systems, making them more willing to purchase discounted, sanctioned Iranian oil.

Crude oil heading to China from Iran involves ship-to-ship transfers in international waters, which can occur multiple times before reaching China, to disguise the origin of the crude oil.

Experts note that the EOPL anchorage area remains as busy as ever, indicating a persistent network facilitating these illicit oil sales. The ongoing activity underscores Iran's persistent strategy to maintain oil exports amidst international pressure and sanctions.
