Last updated: August 2026 dataUnroasted molybdenum concentrates — primarily molybdenite (MoS₂) — are the direct output of flotation circuits at copper-moly mines and represent the raw feedstock stage before calcination. Peru leads US imports under this heading, followed by Mexico and Chile, reflecting the large porphyry copper deposits in the Andes where molybdenum is co-produced. Importers and roasters should ensure that the absence of a roasting step is clearly documented, as misclassification between roasted (261310) and unroasted (261390) material is a recurring customs audit issue.

Unroasted concentrate retains the sulfide mineral form (MoS₂) and has not been thermally oxidized. Roasted material has been calcined to produce molybdic oxide (MoO₃). An assay report identifying the chemical form — sulfide versus oxide — is the primary evidence used to support classification under 261390 versus 261310.
Armenia appears among the top suppliers to the US under this heading, reflecting active molybdenum mining in the Caucasus region. While not as large a source as Peru or Mexico, its presence signals supply diversification opportunities for buyers seeking to reduce concentration risk in Andean supply chains.
