Calcium hypochlorite (perchlorin) manufactured in Iran delivers 65–70% available chlorine in a free-flowing granular or powder form. It is the preferred solid chlorine source for swimming-pool sanitation, emergency water disinfection and industrial bleaching where liquid systems are impractical.

Export destinations focus on Iraq, the Kurdistan Region, Afghanistan, Uzbekistan, Jordan, Oman, Syria, Russia, Georgia, Armenia and Persian Gulf markets that require stable, high-strength solid disinfectants.
