GM and Stellantis weigh Korean auto parts suppliers amid China risks

General Motors and Stellantis met 61 South Korean parts suppliers on Sept. 10, 2026 to review alternative sourcing options as Detroit carmakers accelerate moves away from Chinese components.

The two carmakers joined roughly 20 North American industrial buyers in Chicago for more than 200 individual procurement sessions, according to the Korea Trade-Investment Promotion Agency.

The state-run trade promotion agency targeted multinational manufacturers with annual revenue exceeding $100 million, aiming to address supply vulnerabilities in North American assembly networks.

Rising tariffs and impending regulatory curbs on vehicle communications hardware have forced automakers assembling vehicles in North America to scrutinize component provenance across multiple supplier tiers.

General Motors previously instructed thousands of Tier-1 suppliers to systematically eliminate Chinese materials and subcomponents from vehicles built in the United States, Canada and Mexico.

That directive established a firm compliance deadline of 2027, compelling parts vendors to audit lower-tier supply chains for subcomponents ranging from electronics to stamped metal assemblies.

Stellantis has also intensified scrutiny of its supply base as trade barriers escalate, seeking qualified vendors outside China for battery equipment and electrical subassemblies.

The Chicago trade mission included equipment builders, precision chassis producers and secondary battery materials vendors seeking long-term supply arrangements with Detroit automotive groups.

Procurement representatives from Stellantis focused negotiations on South Korean suppliers capable of delivering machinery and active materials for battery manufacturing facilities under construction.

The carmaker plans to conduct technical evaluations and follow-up commercial discussions with selected vendors from the Chicago meetings, Stellantis purchasing staff said at the event.

Agricultural equipment manufacturer CNH Industrial also sent procurement teams to evaluate South Korean hydraulic systems, mechanical castings and control systems during the sessions.

For South Korean component manufacturers, the shift by North American carmakers represents an opening to capture supply contracts historically held by lower-cost suppliers in eastern China.

South Korean auto parts shipments face zero baseline import duties in the United States under bilateral trade terms, providing a structural cost buffer against Chinese competitors.

Divergent trade policies have widened that margin as Washington applies punitive Section 301 tariffs on Chinese automotive parts, batteries and raw mineral inputs.

Stricter rules from the United States Department of Commerce covering connected vehicle hardware and software add another barrier against sourcing Chinese vehicle electronics.

Automakers must verify that network modules, cameras, sensors and onboard computers contain no software or hardware linked to designated foreign adversaries.

South Korean electronics manufacturers that supply Hyundai Motor Group possess certified manufacturing lines that comply with North American security standards, lowering qualification hurdles for Detroit buyers.

The replacement process remains operationally demanding because automotive qualification cycles typically require 18 to 36 months of testing and tooling modifications before commercial delivery.

Switching established Tier-2 and Tier-3 suppliers also risks increasing unit production costs, challenging automakers already managing lower consumer demand for battery-electric models.

General Motors and Stellantis maintain dedicated operations in South Korea, giving procurement personnel direct access to local engineering teams and regional tier-one supply networks.

General Motors operates assembly and design facilities through GM Korea, while Stellantis sources cells from a domestic joint venture with Samsung SDI.

Those existing operational footprints allow North American engineering teams to audit factory lines and raw material sources without lengthy cross-border establishment periods.

The agency notice does not state whether any binding purchase contracts were signed, and neither General Motors nor Stellantis has published exchange filings confirming new component commitments.

Technical feasibility reviews and pricing audits from the Chicago matchmaking sessions will determine whether initial inquiries convert into multi-year commercial purchase orders.

Automakers face a fixed planning calendar as suppliers work toward the 2027 sourcing deadline set by General Motors for North American assembly lines.
