Serious injury determination: objective evidence must show a causal link between import increases and domestic industry harm. Determination of serious injury or threat requires objective, quantifiable evaluation of factors such as the rate and amount of increased imports, market share taken by those imports, and changes in sales, production, productivity, capacity utilization, profits and losses, and employment. A determination cannot be made without objective evidence of a causal link between increased imports resulting from tariff reduction or elimination under the Trade Agreement and the serious injury or threat, and injury caused by other concurrent factors must not be attributed to those increased imports.
