Trade statistics
International
- UN Comtrade — merchandise trade by commodity and partner, reported by national authorities (comtradeplus.un.org). It has a free tier and an API.
- WTO Stats — trade in goods and services, and tariff data (stats.wto.org).
- World Bank WITS — a front end to Comtrade and tariff databases (wits.worldbank.org).
By country
- United States: the Census Bureau's foreign trade statistics, and USA Trade Online.
- European Union: Eurostat's Comext database.
Notes
Exports reported by one country rarely match the partner's reported imports ("mirror" differences) because of valuation, timing and re-exports.
