Concrete Chaos: Trucker Strike Halts Samsung, SK Hynix Plant Expansions
22 Jun
Summary
- Trucker strike halted concrete deliveries for Samsung and SK Hynix chip plants.
- Around 8,000 union members are participating in the work stoppage.
- Union members rejected a tentative deal, prolonging the strike action.

Industrial action by South Korean concrete truck drivers has led to significant disruptions, raising concerns for major semiconductor plant expansion projects. The National Ready-Mixed Concrete Transport Workers' Union initiated a delivery suspension in the Seoul metropolitan area this week, involving roughly 8,000 members. This action halted concrete pouring at Samsung Electronics' chip plant construction site in Pyeongtaek.
Deliveries were also cancelled for SK Hynix's Yongin chip plant, impacting concrete work there. Although SK Hynix stated the short-term impact is expected to be limited due to construction sequence adjustments, a prolonged stoppage could affect longer-term schedules. The union's action continues after its members rejected a tentative deal with concrete manufacturers.
