Apple Inc. expects tariffs on Chinese imports to lift its costs by about $1.1 billion in the forthcoming fiscal quarter, according to information first reported by TechCrunch. The hit stems from the 145% U.S. levy on Chinese goods that took effect in April and has since squeezed margins across the consumer-electronics sector. To cushion the impact, Apple is accelerating a multiyear supply-chain diversification program, expanding iPhone assembly in India and Vietnam while increasing investments in U.S. manufacturing capacity, people familiar with the plans said. The company discussed the anticipated cost burden during its earnings call two weeks ago, but the updated figure signals a larger near-term drag than previously disclosed.
