Bilateral safeguard determination requires finding a causal link and recommending measures with notification to relevant governments. The Director General must determine within the prescribed investigation period (or authorised extension) whether increased imports have caused or threatened serious injury and whether a causal link exists to the reduction or elimination of a customs duty under the Trade Agreement; recommend an adequate bilateral safeguard measure and its duration (including progressive liberalisation where the period exceeds one year); set out full facts, law and reasons in any affirmative final findings; notify those findings and send copies to the Central Government ministries and the Government of the Republic of Korea.
