Roasted Molybdenum Ores and Concentrates

Roasted molybdenum concentrates (heading 261310) have been thermally processed to produce molybdic oxide, which is directly usable as a steel alloying addition or chemical feedstock. Unroasted concentrates (heading 261390) require further processing. The roasting step adds value and affects classification, so importers must confirm the processing state of the material with their supplier.

Mexico and Chile are the top two suppliers under heading 261310, reflecting their major copper-molybdenum porphyry mining operations where molybdenum is recovered as a byproduct. Canada is also a notable source, and the Netherlands and Belgium appear among recorded suppliers, likely as trading or processing intermediaries.
