Methodology

The data come from CEPII BACI (Etalab 2.0 licence), which reconciles what the exporting and the importing country report, in current USD, FOB. Data up to 2024.

Dependence is the share of a country’s imports (or exports) that each partner accounts for. It does not measure whether a product has a substitute or how much it would cost to change supplier.

The concentration index (HHI) adds up the square of each partner’s share, in percent: it runs from 0 to 10,000. Its equivalent is 10,000 ÷ HHI, the number of partners of the same size that would give that value.

Products are HS4 headings of the 1992 nomenclature (some combine different goods), with a floor of $1 million per product and country.

The EU is the 27 current members in every year; the United Kingdom is outside the EU throughout the series.

Re-exports: countries that act as redistribution hubs carry their notice and the figures are not corrected.
