How this service works
Returns the main trading partners of a country for exports and imports, each with its share, and the concentration of that distribution measured by the Herfindahl-Hirschman index over partner shares. Concentration is the measure that carries the signal: a country sending thirty percent of exports to one state with the rest spread over twenty others is exposed differently from one sending thirty percent to one state and sixty to a second, and the largest partner is identical in both cases.
Output
A structured response listing the top trading partners for exports and imports of the requested country, each with its percentage share of total trade, plus the Herfindahl-Hirschman Index (HHI) value summarizing the overall concentration of the partner distribution — higher HHI signals greater dependence on fewer partners.
Example use cases
Geopolitical supply chain risk assessment
“Give me the import partner breakdown and HHI concentration score for Taiwan — I want to understand how dependent it is on any single country for its imports and flag if the concentration is dangerously high.”
Export market diversification analysis
“Pull the export trading partners and Herfindahl-Hirschman index for Brazil so I can see whether its export revenues are spread across many countries or heavily concentrated in one or two.”
Comparative trade vulnerability screening
“I need the trade exposure data for both South Korea and Mexico — exports and imports — with their HHI scores so I can compare which country has more concentrated trade relationships and therefore higher geopolitical risk.”

Endpoint
POSThttps://stat.halowerk.com/v1/trade-exposureWhen to prefer
Use this endpoint when you need to quantify a country's trade partner concentration and dependency risk beyond just identifying the top partner. Unlike simple rankings, this endpoint provides the HHI metric which captures the full shape of the distribution — ideal for risk models, geopolitical exposure analysis, and supply chain diversification assessments.
Side effects
- Unsupported or invalid country code returns an error
