UltraTech is India's largest exporter of cement clinker. The company's production facilities are spread across eleven integrated plants, one white cement plant, one clinkerisation plant in UAE, fifteen grinding units, and five terminals — four in India and one in Sri Lanka. Most of the plants have ISO 9001, ISO 14001 and OHSAS 18001 certification. In addition, two plants have received ISO 27001 certification and four have received SA 8000 certification. The process is currently underway for the remaining plants. The company exports over 2.5 million tonnes per annum, which is about 30 per cent of the country's total exports. The export market comprises of countries around the Indian Ocean, Africa, Europe and the Middle East. Export is a thrust area in the company's strategy for growth.
UltraTech's products include Ordinary Portland cement, Portland Pozzolana cement and Portland blast furnace slag cement.

Ordinary Portland cement
Ordinary portland cement is the most commonly used cement for a wide range of applications. These applications cover dry-lean mixes, general-purpose ready-mixes, and even high strength pre-cast and pre-stressed concrete.
Portland blast furnace slag cement
Portland blast-furnace slag cement contains up to 70 per cent of finely ground, granulated blast-furnace slag, a nonmetallic product consisting essentially of silicates and alumino-silicates of calcium. Slag brings with it the advantage of the energy invested in the slag making. Grinding slag for cement replacement takes only 25 per cent of the energy needed to manufacture portland cement. Using slag cement to replace a portion of portland cement in a concrete mixture is a useful method to make concrete better and more consistent. Portland blast-furnace slag cement has a lighter colour, better concrete workability, easier finishability, higher compressive and flexural strength, lower permeability, improved resistance to aggressive chemicals and more consistent plastic and hardened consistency.
Portland Pozzolana cement
Portland pozzolana cement is ordinary portland cement blended with pozzolanic materials (power-station fly ash, burnt clays, ash from burnt plant material or silicious earths), either together or separately. Portland clinker is ground with gypsum and pozzolanic materials which, though they do not have cementing properties in themselves, combine chemically with portland cement in the presence of water to form extra strong cementing material which resists wet cracking, thermal cracking and has a high degree of cohesion and workability in concrete and mortar.
As part of the seventh biggest cement manufacturer in the world, UltraTech Cement has eleven integrated plants, one white cement plant, one clinkerisation plant in UAE, 15 grinding units – 11 in India, 2 in UAE, one in Bahrain and Bangladesh each and and five terminals — four in India and one in Sri Lanka..
