How these figures are built
- Selection
- January–July 2026 · Year to date · USD
- Data check
- Only periods whose HS4 data reconciled exactly with HS2 for every partner are shown.
- Method
- MOC four-digit rows summed by TRCC. Special MOC partner codes and quantity are excluded; the partner sum is never presented as World.
Missing does not mean zero. World is never calculated as a sum of country rows. Quantity is absent until its unit is confirmed.
