1Data are rounded to no more than three significant digits.
2Release is the decrease in uncommitted inventory relative to the previous calendar year.
3To estimate Ta content, it was, assumed that natural niobium and synthetic niobium-tantalum ores and concentrates are 32% Ta2O5, tantalum ores and
concentrates are 37% Ta2O5, and Ta2O5 is 81.9% tantalum.
4Includes natural and synthetic tantalum ore and concentrates.
5Includes unwrought powders, unwrought alloys and metals, waste and scrap, and wrought alloys and metal.
6Average annual price per Ta2O5 content as reported in Ryan-s Notes.
7Mass-weighted average value of imported plus exported materials.
