What constitutes evidence of causation?

• A. Any anecdotal claim by a stakeholder.
• B. Evidence linking imports to injury, such as price depression, increased volumes, and production shifts, must show a causal connection to the alleged harm.
• C. Evidence of consumer satisfaction.
• D. Evidence of tariff revenue.

Answer: (B)

Causation in injury determinations hinges on showing a direct link between the imports and harm to the domestic industry. The strongest evidence demonstrates that the imported goods contribute to or cause the injury, with concrete indicators such as price depression or suppression, increased volumes of imports, and shifts in production away from domestic output toward imports. These signs together help establish that the domestic industry is suffering because of the imported product, not merely experiencing general market fluctuations.

Anecdotal claims from stakeholders, while potentially illustrative, do not by themselves prove causation. Likewise, consumer satisfaction and tariff revenue relate more to market performance or revenue effects than to injury caused to the domestic industry by imports, so they do not establish the necessary causal link.
