Market disruption causation requirement: increased imports must be established by objective evidence before safeguard measures apply. Determination of market disruption for transitional product-specific safeguards requires objective, quantifiable evaluation of import increases and domestic industry indicators-including import rate and amount, market share, sales, production, productivity, capacity utilization, profits or losses, and employment-and a demonstrated causal link between increased imports and the disruption; where other factors cause the disruption, it must not be attributed to imports and the case may be referred for anti-dumping or countervailing investigation.
