TradeWeave is a free, open-access global trade analytics platform covering 238 countries, 5,115 products, and 29 years of bilateral trade data from BACI/CEPII. It provides interactive visualizations, country profiles, tariff simulations, economic complexity rankings, and trade forecasting tools.

What data sources does TradeWeave use?

TradeWeave combines data from BACI/CEPII (bilateral trade flows), WITS/TRAINS (tariff rates), World Bank WDI (macroeconomic indicators), ESCAP-World Bank (bilateral trade costs), FRED and BLS (freight indices, exchange rates), and FAOSTAT (agricultural trade).

How can I analyze a country's trade profile?

Visit the Country Profiles page and select any of 238 countries to see their export composition, top trade partners, revealed comparative advantage (RCA), Economic Complexity Index (ECI), trade diversification, and 30-year trends.

What is the Economic Complexity Index (ECI)?

The Economic Complexity Index (ECI), developed by Hidalgo and Hausmann, measures the productive knowledge embedded in a country's export basket. Countries that export a diverse set of sophisticated products score higher. TradeWeave ranks all 238 countries by ECI from 1996 to 2024.

Can I simulate the impact of tariff changes?

Yes. TradeWeave's Tariff Simulator lets you model how tariff changes affect import volumes using real product-level demand elasticities and MFN tariff rates for over 1,200 HS4 products.

How far back does the trade data go?

The primary BACI dataset covers 1996-2024 with HS6 product detail. TradeWeave also includes historical trade data spanning over 200 years (1800-present) from academic compilations.

Tariff Impact Simulator

Armington CES partial-equilibrium model. Simulate bilateral tariff policy changes and quantify effects on trade flows, prices, and welfare. Welfare uses a first-order (Harberger) approximation, most reliable for moderate tariff changes. Pick a preset scenario or build your own below.

Baseline bilateral panel: BACI 202601 (CEPII), bilateral product panel, HS02-HS22, 2002-2024 (retrieved 2026-06-01). For years before 2002 or uncovered HS6 lines, the simulator labels and uses proportional fallback from `bilateral_year`; it never presents that fallback as observed HS96 bilateral trade.

Methodology: Armington (1969) CES partial-equilibrium model. Baseline bilateral flows use the observed BACI bilateral-product panel when available (2002-2024, BACI 202601 (CEPII), bilateral product panel, HS02-HS22, 2002-2024 (retrieved 2026-06-01)); uncovered product-years fall back to labelled proportional allocation from bilateral_year. Substitution elasticities (sigma) at HS6 level from Soderbery (2018), Trade Elasticities, Heterogeneity, and Optimal Tariffs, Journal of International Economics 114; default sigma = 4.0 where no estimate exists. Welfare via first-order Harberger approximation (most reliable for moderate tariff changes). Trade diversion detected via bilateral flow comparison.
