Safeguard duty recommendation after finding increased imports caused serious injury, with phased measures and limited country exclusions. The Authority found that imports of hot rolled flat steel coils had increased sharply during the investigation period and that there was a causal link between the surge in imports and the deterioration of domestic industry indicators, constituting serious injury or threat thereof. Having considered extensive submissions on scope, procedure, unforeseen developments, and public interest, and having accepted adjustment plans from domestic producers, the Authority recommended phased safeguard duties on specified tariff headings over a multi year period with exclusions for developing countries whose import shares fall below the relevant thresholds.
