What types of evidence support a causal link between imports and injury?

• A. Opinion of a single industry official.
• B. Evidence such as price depression, increased import volumes, and production shifts.
• C. Tariff revenue projections.
• D. Consumer preferences.

Answer: (B)

The key idea is showing that imports have caused or contributed to harm in the domestic industry, not just that imports exist. The strongest evidence for that causal link comes from objective, quantifiable indicators that demonstrate how import competition affects domestic producers. Price depression shows that imports are pulling down prices in the domestic market, squeezing profit margins for local firms. Increased import volumes indicate that imports are growing and intensifying competitive pressure. Production shifts reveal how domestic producers adjust in response to competition—reduced output, plant closings, or layoffs point to injury tied to import activity.

These kinds of data together help demonstrate that the injury is connected to imports rather than other factors. In contrast, relying on the opinion of a single industry official doesn’t provide the objective, corroborated basis needed to establish causation. Tariff revenue projections don’t measure harm to the domestic industry, and consumer preferences don’t directly show injury caused by imports.
