U.S. Considers Annual Chip Supply Approvals for Samsung and SK Hynix China Plants

The United States is weighing a proposal to require Samsung Electronics and SK Hynix to seek annual approvals for shipping chipmaking equipment and supplies to their China-based factories, Bloomberg reported Monday, citing people familiar with the matter.

The plan, presented by the U.S. Commerce Department to Korean officials last week, would replace the current validated end user (VEU) designations that granted the chipmakers indefinite export authorizations. Those designations are set to expire at the end of 2025.

Under the draft proposal, Samsung and SK Hynix would need yearly approval for specific quantities of restricted tools and materials, adding regulatory steps but ensuring their Chinese fabs can keep operating. The companies are among the largest foreign chipmakers with plants in China, supplying memory chips vital to global electronics.

Reactions in Seoul were mixed—officials expressed relief that a framework for continued operations remains, but concern over the added bureaucratic burden and potential supply chain uncertainties.

The move comes against the backdrop of intensifying U.S.-China semiconductor tensions. Since 2022, Washington has imposed sweeping export controls to curb Beijing’s chip and AI capabilities. The Biden administration had granted waivers to Samsung, SK Hynix, and TSMC to soften the blow to allied companies, but the Trump administration has pushed for tighter oversight.

The situation is further complicated by political strain: Washington revoked prior waivers days after former South Korean President Lee Jae Myung—who advocated a more balanced U.S.-China stance—signed a defense and investment deal with Trump. Recent U.S. immigration raids on Korean firms’ American subsidiaries have also fueled friction.

Trump to Hit Semiconductor Imports with Tariffs Unless Firms Build in U.S.

President Donald Trump announced Thursday that his administration will impose tariffs on semiconductor imports from companies that do not move production to the United States. Speaking ahead of a dinner with top tech CEOs, Trump said the tariffs would be “fairly substantial” but would not apply to companies already investing in U.S. manufacturing.

Trump framed the move as part of his broader strategy of using tariffs to pressure foreign companies and governments to shift production and jobs into the U.S. “If they are not coming in, there is a tariff,” he said. He singled out Apple CEO Tim Cook, noting that Apple’s $600 billion commitment to domestic investment puts it “in pretty good shape.”

The policy comes as global chipmakers respond to U.S. pressure. Taiwan’s TSMC, South Korea’s Samsung, and SK Hynix have all announced major U.S. semiconductor plant investments. Trump had previously floated a 100% tariff on imported chips but said exemptions would apply for companies producing or planning facilities inside the country.

The announcement underscores Trump’s second-term emphasis on tariffs as a cornerstone of economic and foreign policy, a tool he has wielded to renegotiate trade terms and gain leverage in geopolitical disputes. However, legal challenges loom: lower courts have invalidated parts of his earlier tariff regime, and the administration has asked the Supreme Court to uphold the sweeping emergency powers used to justify them.

South Korea’s Samsung and SK Hynix Exempt from 100% U.S. Chip Tariffs

South Korea’s top trade official, Yeo Han-koo, announced that Samsung Electronics and SK Hynix will not face the proposed 100% U.S. tariffs on semiconductor imports, benefiting from favorable tariff terms under a trade agreement between the U.S. and South Korea.

This comes after U.S. President Donald Trump indicated plans to impose steep tariffs on semiconductor imports from countries without U.S.-based production commitments. However, companies with active or planned manufacturing facilities in the U.S. would be exempt.

Samsung has invested in two chip fabrication plants in Texas, located in Austin and Taylor, while SK Hynix plans to build an advanced chip packaging and AI R&D facility in Indiana. Analysts suggest that Samsung’s broader U.S. investments and its inclusion in Apple’s supply chain give it a stronger exemption position compared to SK Hynix, whose packaging plant alone might not fully qualify for tariff relief.

Apple recently confirmed that Samsung’s Texas plant will supply chips for its iPhones and other products, further strengthening Samsung’s U.S. manufacturing footprint. Following these developments, Samsung’s shares rose 2.6%, while SK Hynix’s shares gained 0.6%, mirroring broader market trends.

Neither company commented on the tariff discussion.
