Why tariff monitoring matters
The US tariff landscape changes faster than any spreadsheet
Federal Register publishes daily
The US government publishes hundreds of trade notices weekly. Most importers never see them until their shipment is held or their margins collapse.
One notice = $10k+ impact
A single USTR or Commerce action can add 12.5–100% to your duty rate. At 25% on a $50,000 container, that's $12,500 you didn't plan for.
Early movers win on sourcing
Importers who catch tariff changes before placing orders can pivot to lower-tariff origins. Those who find out at customs can't.
