## Frequently asked questions

### What does a new corridor signal mean?

It identifies an exporter, buyer market, and HS6 combination included in the available new-corridor signal set for 2024. It is a research prompt, not a guarantee of demand or sales.

### Is the market opportunity reported trade?

Reported buyer imports and exporter share are observations. Any projection or share-gap measure is calculated from the available data and should not be treated as an order or forecast.

### What should exporters check next?

Validate product fit, buyers, tariffs, standards, logistics, pricing, competition, and the depth of product-level history before pursuing the route.

## Method

The signal is a calculated research indicator based on available reported trade observations. It is not a confirmed order, sales forecast, or guarantee of market entry. Validate buyers, tariffs, standards, logistics, pricing, and competition before acting.
