Diet Coke Shortage Hits Indian Cities as Aluminium Can Supply Disrupted by Iran Conflict

New Delhi, April 22, KNT: Several major cities across India are witnessing a shortage of Diet Coke and other canned beverages following disruptions in aluminium can supplies linked to the ongoing Iran conflict, ‘The Economic Times’ reported.
Retailers and distributors reported that the availability of Diet Coke has dropped sharply in recent days, with many outlets either receiving limited stock or facing delays in supply.
The shortage has been attributed primarily to a crunch in aluminium cans, a key packaging material for beverages. Supply chains have been affected after shipping disruptions in the Gulf region, which accounts for a significant share of global aluminium production.
Diet Coke has been among the worst affected products because it is predominantly sold in cans in India, making it more vulnerable to packaging shortages compared to other beverages that are also available in plastic bottles.
Industry executives said companies have begun rationing supplies or are unable to fulfill orders fully due to delays in imported consignments of cans and rising production costs.
Why Aluminium Shortage Is Hitting Beverage Supply
The current shortage of canned beverages in India is primarily linked to disruptions in the supply of aluminium beverage cans, which are widely used for packaging soft drinks and beer.
Aluminium cans are lightweight, recyclable, and preferred for carbonated drinks due to their ability to preserve freshness and withstand pressure. A significant portion of can-grade aluminium and finished cans is sourced through global supply chains, including regions affected by the ongoing Iran-linked disruptions.
Shipping constraints and supply interruptions in the Gulf region have impacted the availability of aluminium, leading to reduced production and delayed imports of cans.
Since products like Diet Coke are predominantly sold in cans in India, they are more directly affected compared to beverages that also have plastic bottle alternatives.
The shortage has forced companies to limit supplies, delay distribution, or shift focus to non-can packaging, highlighting the dependence of the beverage industry on stable aluminium supply chains.
The impact is not limited to soft drinks. Other canned beverages, including beer, are also facing similar supply constraints as the aluminum shortage tightens across the sector.
The disruption comes at a time of rising demand for low-sugar and canned beverages in India, particularly during the summer season, further amplifying the visible shortage in urban markets.
Analysts say the situation reflects a broader global supply chain strain triggered by geopolitical tensions, which have affected raw materials, shipping routes, and energy supplies.
Some companies are pushing alternative products packaged in plastic bottles as substitutes, while efforts are underway to stabilize supply through imports and adjustments in sourcing.
However, industry insiders indicate that the shortage may persist in the near term if disruptions in aluminum supply and logistics continue. [KNT]
