How does the Tariff Commission address intervening factors such as currency fluctuations?

• A. They ignore them.
• B. They rely only on price data.
• C. They assume currency fluctuations are the sole cause of injury.
• D. They assess whether external factors independently explain injury or interact with import intensity.

Answer: (D)

Intervening factors are treated through a causation analysis that asks whether external forces like currency fluctuations can explain the injury on their own, or whether they interact with import intensity to produce the harm. The Tariff Commission does not ignore these factors or rely solely on price data, and it does not assume currency movements are the sole cause. Instead, it evaluates both possibilities: would the injury still occur without the currency effects, and do currency shifts amplify or modify the impact of imports? This approach helps determine whether injury is attributable to imports, to external factors, or to a combination of both, guiding remedies to address the true causes.
