A Global Electronics Association survey released in September 2026 found that two-fifths of manufacturers globally reported extreme heat-related supply chain disruptions this year, with supplier delivery delays identified as the most severe impacts among those affected. Manufacturing Dive reported the findings.
TL;DR
- -A Global Electronics Association survey found two-fifths of manufacturers globally reported extreme heat-related supply chain disruptions, with supplier delivery delays cited as the most severe impacts among those affected.
- -North American results were more mixed, with 57% of respondents reporting no disruptions, though 14% of North American firms expected major or moderate impacts going forward.
- -Chief Economist Shawn DuBravac said there were likely multiple causes and that contingency planning for heat-related supply chain disruptions was essential.
What the Survey Found
Almost half of manufacturers surveyed said supplier fulfillment was most affected, with 50% of manufacturers in North America, Europe, and Asia Pacific reporting disruptions. The picture in North America was more mixed: minor or no disruptions were most common, at 20% and 57% of respondents, respectively, while moderate and major interruptions were each cited by 6%.
Among the disruption types reported by electronics manufacturers who experienced heat-related impacts, supplier delivery delays were cited as the most severe. Other categories included transportation delays, unplanned equipment downtime, and supplier delivery delays, with 17% of North American firms citing these among anticipated or experienced bottlenecks.
How Heat Translates Into Supply Chain Pressure
The survey points to several pathways through which high temperatures reach the supply chain. The most cited anticipated bottlenecks among North American firms that had not yet experienced disruptions were operating constraints, including cooling limits, and power reliability issues, including curtailments, at 29% each.
Global Electronics Association Chief Economist Shawn DuBravac cautioned against treating heat as the sole driver. "There were likely multiple causes, such as labor issues, supplier factory constraints and freight and warehouse bottlenecks," he told Supply Chain Dive. That framing matters for how manufacturers interpret their own exposure: a heat event may compound existing fragilities in supplier capacity, workforce availability, or logistics rather than acting as a standalone cause.
North American Outlook and Planning Implications
Even firms that escaped disruptions in 2026 are not confident they will continue to do so. North American firms that had not experienced heat-related disruptions are still anxious about potential issues. Looking ahead, 14% of North American respondents expected major or moderate impacts, while 32% anticipated minor impacts.
DuBravac drew a direct conclusion from the survey's overall pattern: contingency planning for heat-related supply chain disruptions was essential, he said. The survey does not specify what form that planning should take, but the distribution of anticipated bottlenecks across cooling constraints, power reliability, transportation, equipment downtime, and supplier delivery suggests that exposure varies by where a manufacturer sits in the supply chain and which of those categories its operations or key suppliers are most vulnerable to.
