Important Notes
Export controls are permanent and fully enforced
Unlike the October 2025 rare earth controls (which were suspended in November), Announcement No. 10/2025 has no sunset clause and no suspension. The 2026 dual-use catalogue further institutionalised the restrictions under Category 6C [3]. Chinese sellers refusing to quote tellurium face criminal liability for unlicensed export, uncertain and lengthy licence approval, and a dramatically intensified enforcement environment [4][5][6]. Japan formally complained at the WTO in June 2025 that licence reviews were taking “a very long time” even for clearly civilian items [25]. Buyers should plan for these controls to persist indefinitely.
Supply cannot scale independently of copper refining
Tellurium is almost exclusively a byproduct of electrolytic copper refining, recovered from anode slimes at a ratio of roughly 1 kg Te per 500–1,000 t of copper ore processed [11][12]. Higher tellurium prices alone cannot increase supply — only increased copper refining or improved recovery rates can. This structural constraint makes tellurium uniquely vulnerable to supply-side policy interventions. The entire global market (~980 t/yr) is roughly equivalent to the tellurium content of a single large copper smelter’s anode slime output.
Chemsavers 6N at $243/kg: an anomalous opportunity
The Chemsavers listing of zone-refined 6N tellurium at $243/kg for a 430 g ingot is anomalously low — priced below the investment-grade 4N market ($243/kg) and well below the $1,770+ charged by element retailers for 5N material. This almost certainly represents pre-export-control inventory acquired before February 2025 and priced without adjustment. If still available, it represents an opportunistic buy. Once depleted, replacement stock at this purity and price point is unlikely [19].
First Solar is the single most important demand variable
CdTe photovoltaics consume ~60% of global tellurium, and First Solar is the dominant CdTe manufacturer with ~14 GW of nameplate capacity scaling to 17.7 GW by 2027 [8][9]. A February 2026 DOE-backed paper in Joule outlined a pathway to 100 GW/yr of global CdTe capacity by 2030, which would fundamentally transform the tellurium market [7]. First Solar’s secured supply chain through Rio Tinto Kennecott and 5N Plus partially insulates it from Chinese export controls, but any significant expansion beyond current capacity will require new tellurium sources.
