Method & machine-readable

Source: US Census Bureau port-level trade (port of unlading, verified — landlocked ports report zero vessel weight). Grand-total rows only for totals; DET country rows for the breakdown — the overlapping APEC/OECD groupings Census ships in the same response are excluded, or every figure would read ~3× too high. Census revises prior months; this mirror archives every restatement. Cross-checked against independent AIS observation of the same gateways (method).
