Methodology:
Estimated actual entry under MFN terms, as a percentage of total imports in 2025: For China and the EU, the percentage in 2025 is initially calculated by deducting imports from partner countries with FTAs and imports entered under GSP schemes from total imports. For China, imports from US subject to retaliatory Chinese tariffs are also deducted. For the EU data are only available through October 2025. For the US, the percentage in 2025 (January to November) is calculated by deducting imports from FTA partners and partners subject to the exceptional tariffs from total imports. WITS data on MFN eligible dutiable imports and duty-free eligible imports are most recently available for 2022.

Eligible for MFN entry, as a percentage of total imports in 2022 (WITS): This is calculated by MFN dutiable imports plus MFN duty-free imports, divided by total imports in the given year.
