Iran: Cement output fell by 10% year-on-year to 31.7Mt in the first half of 1403 (21 March – 22 September 2025), down from 35.1Mt, according to Ali Akbar Alvandian, secretary of the Cement Industry Association. He attributed the decline to weaker domestic demand and energy constraints.
Clinker output also dropped by 10% in the first quarter (21 March – 21 June 2025), recovered in July and August 2025, then declined by 4.5% in September 2025. Cement production in the sixth month (22 August - 21 September) fell to 5.7Mt from 6.4Mt a year earlier.
Exports rose by 7% to 6.9Mt of cement and clinker, while domestic demand fell by about 10%. A nationwide power cut in May 2025 reportedly halted production and temporarily increased prices.
