Germanium

India is currently navigating a complex situation involving export restrictions imposed by China on germanium, a critical mineral used in several high-tech industries. Here’s a breakdown of the key points:

What is Germanium?

• Uses: Germanium is essential in manufacturing:
  • Semiconductors
  • Fiber optic cables (especially in the “core of the preform”)
  • Solar panels
• Supply Chain Significance:
  • Over 50% of global germanium production comes from China.
  • India does not produce germanium domestically and relies entirely on imports.

China’s Export Restrictions

• China placed germanium under export licensing, tightening controls.
• China banned most exports of germanium and gallium to the U.S., citing national security concerns.
• These moves have disrupted global supply chains, particularly in electronics and photonics.

India’s Position

• The Indian government is now engaging with China to manage and potentially ease these restrictions.
• The fiber optics industry in India is particularly vulnerable:
  • Germanium oxide is crucial for the “core of the preform,” a vital component in drawing high-quality optical fibers.
• These disruptions could hinder India’s ambitions in expanding digital infrastructure, 5G rollout, and semiconductor manufacturing.

Strategic Implications

• Germanium is not a Rare Earth Element (REE), though it is similarly critical and monopolized in its supply.
