Inventory in 'decent shape'
Mazda's plants in Hiroshima and Hofu were idled from March 14 through March 21 before resuming temporary production three days ago using parts in stock. The plants are scheduled to be idled again starting Monday.
Mazda's assembly plants are farther from the earthquake zone than other automakers' factories, except one Toyota plant and one Nissan factory on the southernmost island of Kyushu.
Amestoy said the automaker is "in decent shape" with current U.S. stockpiles, though he declined to give details.
"We're fairly comfortable at the moment," Amestoy said. "We have a good supply and mix of models, trims and colors."
The automaker's U.S. sales are up 3 percent through February in a market that has advanced 23 percent.
Mazda had a 94-day supply of vehicles in dealer stocks as of March 1, down from 123 days on Feb. 1, according to the Automotive News Data Center. A 60-day supply is considered normal.
Honda Motor Co. this week suspended U.S. dealer orders for vehicles imported from Japan, including the Honda Fit, CR-V, Insight, CR-Z, Civic Hybrid and Acura TSX and RL. Nissan Motor Co. also said it would reduce its planned vehicle allocation volume for May by half. The other half will be released when Nissan confirms those vehicles will be ready.
Toyota Motor Corp. and Mitsubishi Motors Corp., haven't suspended dealer orders.
Unlike its bigger rivals, who assemble most of the vehicles they sell in the United States, Mazda imports the majority of vehicles it sells.
In 2010, imports accounted for about 83 percent of the brand's U.S. sales. The Mazda3 compact sedan, the brand's best-selling car, accounted for about 46 percent of Mazda's U.S. demand last year.
Dealers held a 102-day supply of the Mazda3 on March 1, down from the 160-day level of Feb. 1.
Dealers can still order the Mazda6 midsize sedan and Tribute crossover. The Mazda6 is built at the Auto Alliance International plant in Flat Rock, Mich., and the Tribute is assembled at Ford Motor Co.'s plant near Kansas City, Mo.
