Serious injury determination requires objective, quantifiable evidence and a demonstrated causal link to increased imports. Determination of serious injury requires evaluation of objective, quantifiable factors including the rate and amount of increased imports, market share taken by those imports, and changes in sales, production, productivity, capacity utilisation, profits and employment. A determination must be based on objective evidence demonstrating a causal link between increased imports and the injury; injury caused by factors other than increased imports must not be attributed to those imports.
