How to cite

CEPII — BACI: International Trade Database at the Product-Level, V202601. Aggregated to country-pair totals (HS6 product dimension summed) by the Elkassabgi Data Library. Licence Ouverte / Open Licence 2.0 (Etalab). Last update: 2026-01-22.

Processing: Country-pair totals derived from BACI HS96 by summing value (1000 current USD) and quantity (metric tons) over all HS6 products per exporter-importer-year. NOT BACI's native product-level grain.
