US-Made Cover Glass to Feature on All Future iPhone and Apple Watch Models

Apple Keeps Timeline Under Wraps for US-Made Corning Glass on iPhone and Apple Watch

Apple and Corning have taken their long-standing collaboration to the next level with a major new investment. On Wednesday, Apple announced it would inject an additional \$2.5 billion (roughly Rs. 21,900 crore) into Corning’s operations to produce cover glass for every iPhone and Apple Watch model at the company’s Harrodsburg plant in Kentucky. This marks the first time that all cover glass for these devices, sold globally, will be manufactured entirely in the United States. Alongside the production boost, the project will lead to a significant increase in local employment and the establishment of a dedicated innovation centre at the facility.

According to Apple’s statement, the Harrodsburg plant will be responsible for producing the cover glass for the entire iPhone and Apple Watch lineup worldwide. The site already manufactures Apple’s Ceramic Shield glass, which has been a key selling point for the brand’s durability claims. By centralising all production in Kentucky, Apple aims to ensure higher supply chain resilience and reinforce its commitment to US-based manufacturing.

Corning’s Harrodsburg plant is recognised as the largest and most advanced smartphone glass production line in the world. With the expansion, the facility will now be fully dedicated to Apple’s needs. The move is expected to grow Corning’s local workforce by around 50 percent, creating hundreds of new jobs in the region. The innovation centre being set up alongside the production line will focus on developing cutting-edge materials and manufacturing techniques for future Apple products.

This expansion comes at a time when tech companies are under increasing pressure to localise manufacturing and reduce reliance on overseas suppliers. For Apple, the decision not only supports domestic industry but also strengthens its strategic relationship with Corning, a partner of over a decade. With these changes, Apple is positioning itself to deliver stronger, US-made components while also investing in next-generation innovation that could shape the future of its product line.
