What is the significance test in tariff investigations?

• A. A test to determine whether tariffs are legally permissible.
• B. A standard assessing whether evidence indicates likely injury or causal relationship between imports and harm to domestic industry; criteria vary by jurisdiction.
• C. A test for evaluating public opinion on tariffs.
• D. A statistical test to measure tariff revenue.

Answer: (B)

The significance test in tariff investigations is about whether there is evidence of a likely injury to the domestic industry or a causal link between the imported goods and that harm. In practice, authorities examine evidence such as price effects, lost production, reduced sales, and impacts on employment to determine if imports are causing or contributing to injury, with the exact standards and thresholds varying by jurisdiction. This makes it a test of injury and causation rather than questions of legality, public opinion, or revenue—hence the best description is that it assesses whether evidence indicates likely injury or a causal relationship, with different jurisdictions applying different criteria.
