^eEstimated. ^rRevised.
¹Data are rounded to no more than three significant digits.
²Based on calculations by the U.S. Geological Survey.- Secondary rhenium production not included.
³Based on 80% recovery of estimated rhenium contained in molybdenum disulfide concentrates.
⁴Calculated as production plus imports minus exports and industry stock changes.
