Bilateral safeguard measures: Director General must investigate import surges causing serious injury and recommend adequate remedial measures and duration. The Director General must investigate whether eliminated or reduced customs duties under the Trade Agreement have led to increased imports that cause or threaten serious injury to the domestic industry, evaluating objective factors such as import increases, market share, sales, production, productivity, capacity utilisation, profits and employment, and must submit findings and recommend appropriate bilateral safeguard measures, their duration and progressive liberalisation where applicable, and review the need for continuation.
