| COLUMN | TYPE | DESCRIPTION | UNIT |
|---|---|---|---|
| year | int64 | Calendar year of the export quarter (2015-2024). | - |
| quarter | string | Quarter of the reporting year. Values: Q1, Q2, Q3, Q4. | - |
| mineral | string | Mineral type slug. Values: cassiterite (tin ore), wolfram (tungsten ore, labeled "Wolfram" in the volume table and "Wolframite" in the value table - both mapped to this slug), gold, other_minerals (a residual category covering all other exported mineral types including coltan/tantalite and gemstones). | - |
| volume_kg | float64 | Export volume in kilograms for the given year, quarter, and mineral. Null for gold in 2015-2018 (RMB systematic tracking of gold exports began in 2019). Some 2020 values include one decimal place (e.g. 565,993.2 kg) reflecting the source encoding; these are stored as float64 without rounding. | kg |
| value_usd | float64 | Export value in US dollars for the given year, quarter, and mineral. Null for gold in 2015-2018 (same tracking-start reason as volume_kg). | USD |
