Germanium from China — Ingot, Dioxide, Tetrachloride
China is the largest producer of primary germanium, recovered from zinc refining and coal fly ash in Yunnan and Inner Mongolia. We supply zone-refined germanium ingot, germanium dioxide, germanium tetrachloride and germanium optical blanks from licensed Chinese producers to fibre-optic, infrared-optics, semiconductor and solar buyers.
Live China germanium prices are shown below. Germanium products are subject to China's export-licence regime; we manage licensing with the producer.

Compliance & quality
Every enquiry is screened before quotation: strategic-items self-classification (Korea YESTRADE) and buyer screening against the U.S. Consolidated Screening List and UN/EU sanctions lists. We do not quote sanctioned parties, military end-users or embargoed destinations.
Materials ship with mill/producer certificates of analysis (ICP-MS/GDMS as applicable). Samples are available for independent third-party assay before volume orders.
Semiconductor finished goods are sourced on a demand basis from authorised Chinese producers and distributors only — no EOL brokerage, no unverified stock. Sample lots are verified before shipment.
