Serious injury determination requires objective evidence of a causal link between increased imports and harm to the domestic industry. Determination of serious injury requires the Director General to evaluate objective and quantifiable factors-including import increases, market share, sales, production, productivity, capacity utilisation, profits and employment-and to establish on the basis of objective evidence a causal link between increased imports under the Trade Agreement and the serious injury or threat; injuries caused by factors other than increased imports must not be attributed to those imports.
