The production drew hundreds of eager spectators to a ceremony north of the capital to taste the chocolate ice cream, which measured 1.6-meters (five feet) by two meters (seven feet) and which producers say cost over $30,000 to make.
Board Member Mohammad Baheri of Choopan Dairy said the company aimed to register a new Guinness World Record and also boost Iranian ice cream consumption.
A Guinness World Records representative visited the tub, he added.
Iranians eat an average 1.5 kilograms (3.3. lb) of ice cream per year. The current record belongs to U.S. producer Baskin-Robbins, which made an 8,865 lb (4,021 kg) tub in 2005.
