The annual seaborne movement of the major dry-bulk and energy commodities — iron ore, coal, grain, crude oil and gas — by leading trading nation. The global trade-flow layer that complements live vessel tracking: who moves how much of what by sea, and how the volumes are trending.
Annual reported tonnage moved by sea for each major dry-bulk and energy commodity, across a fixed set of leading trading nations. Year-to-year reporting coverage varies, so early-year spikes or level shifts reflect which nations had filed, not demand changes.
Annual net-weight trade for a fixed set of leading trading nations in each commodity, aggregated across all partners — not a global total. The “top importers/exporters” lists rank only those tracked nations, so the world’s largest movers may be absent. Import and export tonnage are each counted over the nations tracked on that side, so the two are separate readings of the trade rather than two views of the same cargo, and they will not match. Tonnage moved is the seaborne-demand primitive behind freight; the trend line is each commodity’s total reported import volume over the available years, and reflects which nations had filed in each year rather than demand alone — coverage varies year to year, so early-year spikes or level shifts are composition artifacts, not demand changes. The most recent year is provisional and under-reported (fewer nations have filed their annual data), so its totals will rise as more reporters file. Trade lanes →
