Honda supplier rethinks China relationship as trade war bites

As the U.S.-China trade war expands into the auto, steel and rare earths sectors, few companies are feeling the pressure more than top Japanese car parts supplier Daido Steel.
The supplier to Honda and other major marques is facing a trio of headwinds: a 50% tariff on U.S. imports of steel, a 25% duty on foreign-made cars and a levy on parts, and China's tightening of exports of rare earths — minerals critical to make magnets for car motors.
"They've started putting up walls,' CEO Tetsuya Shimizu said in an interview at Daido Steel's headquarters in Nagoya. "This will have a massive impact on the stability of the global economy.'
It's also having major implications for the sprawling network of specialty manufacturers that are critical to the global automotive industry and now find themselves stuck between feuding superpowers.
For Daido Steel, the trade war has meant renewing a push to build rare earth supply routes outside of China, which accounts for almost 70% of mined material and about 90% of global refining of the metals.
Some new routes are already starting to form, mainly from Australia, and Shimizu said there's potential in the United States, Canada and Brazil. But progress has been slow due to high costs and low supply, he said, underscoring the immense challenge facing the world's efforts to wean from dependence on China.
Daido Steel's struggles also signal the true toll of the trade war on the auto sector will be magnitudes more than the billions of dollars forecast by top carmakers including Ford and Toyota. And the constant roller coaster of escalating, then deescalating, tensions has left companies scrambling to maintain business ties under a cloud of uncertainty.
When U.S. President Donald Trump initially imposed 25% tariffs on steel imports in March, Shimizu was able to reassure clients in the U.S. that business could continue as normal. Customers value Daido Steel's products enough to wait months for shipments to arrive and, if they could buy comparable goods domestically in the U.S., "they'd already be doing it,' he said.
But his confidence vanished earlier this month when duties doubled.
"At some point it stops making sense as a business,' Shimizu said. "Asking customers to pare back orders or lean on inventory or lower production could negatively impact the entire enterprise, but that risk might be unavoidable.'

Daido Steel earns most of its money supplying products to Japan's automakers — many of which sell cars in the U.S. that are manufactured or assembled elsewhere. Collectively, the top Japanese auto brands are bracing for a $19 billion hit from tariffs.
Several Japanese carmakers have already started to shift or lower U.S. production, leaving suppliers like Daido Steel at the mercy of their customers' rapidly changing plans. In May, the steelmaker withheld full-year profit guidance for the current fiscal year and forecast a 34% drop in first-half net income.
"It comes down to how carmakers respond,' said Mikine Kishi, general manager of the company's corporate planning department. "If they decide they're not going to manufacture in Japan anymore, or that they'll lower total production volumes, that would have an extremely big impact on our business.'
The U.S. and China appear to have reached a detente, and Trump has signed an order that prevents multiple tariffs from piling on top of each other. But rare earths are proving to be a particular sticking point in trade negotiations.
China's export controls on seven individual elements, and magnets that contain even tiny amounts of them, left sectors from auto to defense urgently trying to find workarounds. Uncertainty over supply lingers, though Beijing said this month it is accelerating the review of rare earth export license applications and has approved some requests.
Daido Steel had a head start in diversifying its supply chain. Back in 2010, China briefly imposed a de facto ban on exports of rare earths to Japan following a maritime dispute, kick-starting industry efforts to break their reliance on the nation. Success has been limited though: Japan depends on China for 60% of its rare earths supply, down from 80% to 90%.
As well as seeking alternative supplies, Daido Steel focused on new technology to use fewer rare earths.
One of the company's key products is a neodymium magnet that doesn't include heavy rare earths, including dysprosium or terbium, which has been used by Honda since 2016. Daido Steel also supplies magnets indirectly to automakers by way of Aisin and Denso — two of Japan's biggest suppliers.
Daido Steel wants to expand production and industrial use of those magnets, betting that customers will increasingly look for non-Chinese supply. It also plans to build a manufacturing plant in the U.S., though Shimizu didn't specify when or where that will happen.
It would be a major disappointment if the U.S. should slide into authoritarianism, Shimizu said, because that would mean the global economy will eventually have to revolve around America.
"I'm not sure there's enough time for supply chains to transition if the goal really is to produce everything in America for America,' he said.
