WASHINGTON, Feb 16 (Reuters) - The U.S. Commerce Department has recommended that President Donald Trump impose steep curbs on steel and aluminum imports from China and other countries ranging from global and country-specific tariffs to broad import quotas, according to proposals released on Friday.
The long-awaited unveiling of Commerce's "Section 232" national security reviews of the two industries contained global tariff options of at least 24 percent on all steel products from all countries, and at least 7.7 percent on all aluminum products from all countries.
The recommendations were presented to Trump last after he authorized the probes under a 1962 trade law that has not been invoked since 2001. He has until April 11 to announce his decision on steel import curbs and by April 20 to decide on aluminum restrictions.
U.S. Commerce Secretary Wilbur Ross emphasized that Trump would have the final say, including on whether to exclude certain countries, such as NATO allies, from any actions.
"The president has the discretion to modify any of these or to come with something totally different," he told reporters on a conference call.
He said a global tariff would cover every steel and aluminum product entering the American market from China.
Steel stocks soared with U.S. Steel closing up 14.7 percent, AK Steel up 13.7 percent, Nucor ended up 4.5 percent and the broader S&P 1500 steel index 5.3 percent higher.
Century Aluminum shares closed up 8.3 percent, while Alcoa, which has operations across the globe, ended off 0.44 percent.
Alcoa said in a statement the U.S. trade actions should focus on Chinese overcapacity and not penalize nations that abide by the rules.
Ross said he would not be surprised if countries challenged the measures at the World Trade Organization.
He said "there has been no dialing back" of the recommendations due to objections from industries that use steel and aluminum.
"The objective of both reports is to get the production up to a level which will result, in our judgment, in the long term viability of each industry," Ross said, adding that he did not believe that the recommendations would lead to significant price hikes.
U.S. Senate Democratic leader Chuck Schumer said he hoped the proposals "are the beginning of efforts by this administration to finally get tough on China."
SPECIFIC COUNTRY OPTIONS
Alternatively, Commerce recommended a steel tariff of at least 53 percent on all steel imports from 12 countries -- Brazil, China, Costa Rica, Egypt, India, Malaysia, Russia, South Korea, South Africa, Thailand, Turkey and Vietnam.
Other countries would be subject to a quota limiting their tariff-free access equal to their 2017 steel exports to the United States.
The country-specific aluminum tariff option would impose a 23.6 percent tariff on all products from China, Hong Kong, Russia, Venezuela and Vietnam. All others would be subject to quotas equal to their 2017 exports to the United States.
A third option called for Trump to impose global quotas based on 63 percent of each country's 2017 steel exports and based on 87 percent of their aluminum exports to the United States.
Ross said the remedies were designed to raise U.S. capacity utilization to about 80 percent for each industry, from the current 48 percent in aluminum and 73 percent in steel.
"That is the level we believe would provide the industry with long term viability," he said.
Some U.S. companies will be able to request exclusions for specific products if the U.S. lacks sufficient domestic capacity or for national security considerations, Ross added.
Philip Bell, president of the Steel Manufacturers Association, welcomed the proposals saying they could be "meaningful and effective" in tackling global excess capacity and relentless steel imports.
But in a joint statement the National Tooling and Machining Association and Precision Metalforming Association said steep tariffs would "devastate" downstream U.S. steel consuming manufacturers, which employ 6.5 million Americans.
"If these tariffs are imposed, the U.S. will become an island of high steel prices resulting in our customers simply importing the finished part and threatening thousands of jobs," the groups said.
Cowen and Co. analysts Novid Rassouli and Han Zhang told clients in a research note they believe Trump will likely go for more targeted options.
"Utilizing a blanket tariff is too broad, in our view," they said. "There is a higher level of precision needed than a blanket tariff because depending on the product spread, it could for instance knock out one product, and do little to nothing for another."
Trump met with a bipartisan group of U.S. senators and representatives at the White House last week, signaling he would take at least some action to restrict imports of the two metals.
Some U.S. lawmakers and steel and aluminum users have urged caution in any restrictions to avoid disruptions or price spikes in the raw materials, used in everything from autos to appliances and aircraft and construction.
