Severe flooding across central Thailand has temporarily halted manufacturing at four Toyota plants and multiple auto-parts suppliers, disrupting regional supply chains and delaying deliveries.
Flooding in Thailand’s central region and eastern industrial estates has forced major automotive manufacturers to pause production. The severe weather disrupted transport routes and logistics networks, leaving workers unable to reach assembly plants while inundating factories with standing water.
Toyota and Isuzu Operations Halted by Parts Shortages
Toyota Motor Thailand temporarily suspended operations at its Samrong, Banpho, and Gateway manufacturing facilities due to severe flooding. The production pause affected regional supply chains, leading to delivery delays for popular export models including the Hilux, ATIV, Land Cruiser FJ, Camry, Corolla Altis, and Corolla Cross destined for overseas markets like the Philippines.
According to the Thai Auto-Parts Manufacturers Association, roughly 10 auto parts manufacturers nationwide suspended operations after floodwaters prevented employees from reaching factories. These component shortages subsequently disrupted operations at several major automakers, including Toyota, Isuzu, Ford, Nissan, and Honda. In addition to vehicle production sites, Honda’s motorcycle plant located in Lat Krabang was forced to pause operations when flooded streets prevented employees from reaching the facility. That specific plant is capable of producing up to 1.67 million motorcycles annually, turning out widely used local models such as the Wave 110 and the Scoopy.
Amata City Chonburi Flooding Exposes Just-In-Time Vulnerabilities
The disruption hit hard inside Amata City Chonburi Industrial Estate, where an earthen flood embankment collapsed and inundated zones 7, 8, and 9. More than 10 auto-parts factories were among 34 plants forced to stop production in the estate.
Suwat explained that Japanese carmakers rely heavily on the Toyota Production System and just-in-time manufacturing, meaning facilities do not maintain large component inventories. Tier 2 and Tier 3 parts suppliers in Chonburi province were heavily impacted when waters inundated their operations late last month, forcing them to temporarily halt production. These small- and medium-sized enterprises serve as original equipment manufacturers and supply components to major vehicle assemblers.
Assembly plants still have some parts, so they can keep going for now.

When single-source components are produced solely by a flooded supplier within the estate, carmakers have little immediate recourse. Supoj Sukpisan, honorary chairman of the FTI’s Auto Parts Industry Club, noted that affected companies are dependent on restoring local machinery or importing emergency replacements.
Industrial Losses Approach Six Billion Baht
Industrial water pumps and drainage channels have been used to accelerate recovery.
To assist the recovery effort, the Thai government has earmarked approximately two billion Thai baht for flood relief for victims. The Thai Chamber of Commerce is gathering additional information to assess the economic impact across agriculture, tourism, services, and other manufacturing industries.
Production Resumption Timelines Set for Mid-October
As floodwaters recede from factory floors, engineers and technicians are cleaning machinery and inspecting electrical systems. Affected auto-parts makers anticipate that production will resume starting October 14, allowing assembly lines to restart deliveries and ramp up output to meet both domestic and export demand in the coming weeks.
