How Chinese Materials Export Restrictions Impact Electronic Components

On December 3, 2024, Chinese Commerce Ministry announced an export ban on critical materials like gallium, germanium, and antimony, citing national security concerns. This decision closely followed the U.S. Bureau of Industry and Security’s (BIS)  adding 140 entities, primarily Chinese, to its Entity List on December 2, heightening tensions in ongoing trade disputes. The newly listed entities include organizations from Japan, South Korea, Singapore, and China, with Chinese entities being the most affected—accounting for 125 of the 140 additions. These actions underscore escalating tensions in the global trade of advanced technologies.

China's new rule, effective immediately, bans exports of gallium, germanium, antimony, and other materials critical to high-tech industries specifically to the U.S. This decision goes beyond previous measures, which only required export licenses and didn’t target specific countries.

The notice outlines two main restrictions translated by Center for Security and Emerging Technology:

Military Use: Exports of these materials to the U.S. for military purposes or to military users are completely banned.

Tightened Checks: The export of gallium, germanium, and antimony to the U.S. is generally not allowed. 

This move is expected to significantly impact industries like semiconductors and defense, heightening trade tensions between the U.S. and China.

Understanding What Are Gallium, Germanium, and Antimony?

Gallium (Ga):

Gallium is a critical material used in the semiconductor and consumer electronics industries. It is not found in its natural form but is extracted as a byproduct when refining metals like zinc and aluminum from bauxite ore. Gallium is essential for creating compound semiconductors, which are used in LEDs, solar panels, and high-speed electronics.

Germanium (Ge):

Germanium is another important element for high-tech applications, particularly in semiconductors and fiber optics. Like gallium, it does not occur naturally and is produced as a byproduct during the processing of zinc and other metals. Germanium is also used in infrared imaging systems and advanced solar cells.

Antimony (Sb):

Unlike gallium and germanium, antimony is a naturally occurring element. It is often combined with other metals to form strong alloys used in various applications, including batteries, semiconductors, and diodes. While not exceedingly rare, it is less abundant than more common industrial metals.

Gallium, Germanium, and Antimony Global Market

The U.S. depends heavily on China for its gallium supply, China produces approximately 95% of the world's supply of raw gallium, as reported by the U.S. Department of Energy. The U.S. lacks enough domestic resources to meet the growing demand for critical materials such as gallium and cobalt.

China is the dominant producer of germanium, accounting for 80% of global production between 2012 and 2016.

By 2022, China produced 55% of the world’s antimony from mining operations. The U.S. does not have domestic antimony mining, relying on imports for about 85% of its supply. The main suppliers to the U.S. include China, Italy, Belgium, and India. Other significant sources of antimony mining globally are found in countries such as Australia, Bolivia, Burma, Mexico, Russia, South Africa, and Tajikistan, according to the United States Geological Survey (USGS).

How Many Parts Are Affected by These Bans?

Close to 1,000 suppliers produce components containing at least one of the banned elements. These components span across different categories, including: Semiconductors, Cables and Wire Management, Power and Circuit Protection, Electromechanical Components, LEDs, Memory Modules, Optoelectronics, Sensors, Test and Measurement Equipment, Thermal Management Components, Tools and Production Supplies. 

An estimated 700,000+ parts are expected to be impacted by these bans. The majority of the affected components contain antimony (94%), followed by gallium (3%), germanium (2%), or a combination of these elements.

Upcoming Challenges for Manufacturers and Suppliers

1. Supply Chain Disruptions

Increased Costs: The scarcity of critical materials like gallium, germanium, and antimony will drive up procurement costs, affecting profit margins.
