Safeguard duty determinations require proof of serious injury, a causal link to imports, and recommendations on appropriate measures. The Director General must determine within the statutory period whether increased imports have caused or threatened to cause serious injury to domestic industry and whether a causal link exists, issue public findings with factual and legal reasons, and send notice to the Ministries of Commerce and Finance. If affirmative, the Director General must recommend appropriate measures and their duration, including possible use and allocation of tariff rate quotas, principles for quota levels, carry forward of unused quota, residual quotas, and progressive liberalisation for multi year measures.
