How does the supply chain mapper work?

Search for any HS product code and see which U.S. states consume the most imports of that product, which ports handle the most volume, and which countries are the primary sources. Data comes from Census Bureau State HS and Port HS trade statistics.

What data sources power this tool?

This tool combines data from three Census Bureau endpoints: imports by HS code (country origin), imports by state and HS code (destination state), and imports by port and HS code (port of entry). No other free tool offers this geographic flow view.

Understanding Import Supply Chains

U.S. imports follow specific geographic patterns. Electronics from Asia typically enter through West Coast ports (Los Angeles, Long Beach) and flow to tech hubs like California and Texas. Vehicles from Europe enter through East Coast ports (Baltimore, Brunswick) and distribute to the Midwest. This tool reveals these patterns for any product.
