Where is an importer's supply chain concentrated?
Enter a U.S. importer and see sourcing-country concentration, port concentration, and a 12-month shipment trend — modeled from cached customs data. Indicators only, never legal or tariff advice.
Only the company is needed. Indicators are estimates from public, aggregated customs records — not legal or tariff advice.
All figures are estimates from public, aggregated shipment records and are labeled as indicators. Nothing here is legal, customs, or tariff advice.
See how dependent an importer is on a single sourcing country or port — a fast read on supply-chain fragility.
Every figure is a labeled estimate from public customs data. We never make legal, duty, or classification determinations.

Frequently asked
Is this legal or tariff advice?
No. The scanner surfaces concentration and trend indicators derived from public, aggregated shipment records. It does not classify goods, determine duty treatment, or provide legal, customs, or tariff advice. Verify any trade-policy impact with a licensed customs broker or trade attorney.
Where does the data come from?
From cached U.S. customs / bill-of-lading records — the same grounded shipment data our platform uses internally. Concentration shares and shipment counts are modeled estimates over a trailing 12 months and are labeled as indicators.
What does 'import concentration' mean?
It's the estimated share of an importer's shipments coming from its single largest sourcing country, plus how many distinct countries they source from. A high top-country share is flagged as a higher concentration indicator — a signal to look closer, not a conclusion.
What if the company isn't found?
We tell you honestly rather than invent numbers — just try another importer. We only report on companies we already have a cached profile for.
What unlocks with an account?
Supplier-level concentration, full lane detail, shipment records, and — most importantly — Pulse monitoring so you're alerted when a company's sourcing or lanes shift. A free account saves the company and opens its live Pulse view.
