Diet Coke, produced by Coca-Cola, is facing a significant shortage in several major cities across India, including New Delhi, Mumbai, and Bengaluru, due to a severe supply disruption of aluminium cans caused by the ongoing Iran war. This crisis has led to stock-outs of Diet Coke and other canned beverages, coinciding with a peak demand season as summer temperatures rise. A leading grocery retailer in Delhi-NCR reported acute shortages since the weekend, with remaining supplies being quickly purchased by consumers. Unlike other beverages, Diet Coke is primarily packaged in cans, making it more susceptible to the current supply chain issues. Companies are now forced to import aluminium cans from countries like the UAE and Sri Lanka at 25-30% higher costs. The Federation of European Business in India has requested the government to temporarily suspend customs duties on imports of packaging materials to alleviate the situation. The combined impact of rising demand for low-sugar drinks and supply constraints could affect sales in the packaged soft drinks market, which is already recovering from last year's downturn due to unseasonal rains.
