Supply Chain Card Explained
The Supply Chain card is a freight and logistics context card. It watches public port, shipping, import/export, and rail/intermodal signals for broad congestion or flow changes.
Quick read
- Useful for
- Supply-chain strain can affect fuel, retail availability, disaster response supplies, travel, and recovery timelines.
- Watch
- status label, trigger, anchored ships, port signal, imports, exports, rail/intermodal, source period, source age, and refreshed time.
- Confirm with
- BTS supply chain and freight indicators
- Remember
- Freight indicators are usually delayed and aggregated; they do not forecast a specific store shelf or shipment.
How to read this card
- Status: compact label such as Normal/Watch/Elevated based on public freight indicators.
- One-line text: usually the port signal or primary congestion context.
- Freight/Rail line: rail or intermodal context when available.
- Source period: the reporting period represented by the source, not necessarily today.
Hover card metrics explained
- Trigger: strongest reason for the current rating.
- Anchored ships: containerships anchored off U.S. ports; higher can indicate port congestion but may also reflect weather or scheduling.
- Port signal: text summary of port throughput/congestion context.
- Imports: import-flow signal from the source period.
- Exports: export-flow signal from the source period.
- Rail/intermodal: rail or intermodal freight context where provided.
- Source age: time since the source data period or source update.
- Refreshed: HazardNow cache refresh timing.
What can make this status change?
- Port congestion rises or clears.
- Imports/exports or rail/intermodal indicators shift sharply.
- Weather, labor issues, cyber incidents, fuel constraints, or global events affect freight flows.
- A source publishes a new reporting period or the cache becomes stale.
Limitations
Supply-chain data is broad and delayed. It should be treated as context for logistics strain, not a precise forecast of consumer availability or delivery time.
Sources and update behavior
HazardNow uses cached public freight indicators, including BTS supply-chain/freight context where available. Updates follow source release timing and dashboard cache refreshes.
Visual reference
Supply chain signal map
Read the signal as one layer in a larger source stack, not as a standalone instruction.

FAQ
Do anchored ships mean shortages are happening?
Not by themselves. Anchored ships are one congestion clue that must be read with port, rail, imports, exports, and timing context.
