Technical-grade hydrochloric acid at 31–33% concentration is shipped from Iran as a clear to pale-yellow corrosive liquid. It is the workhorse acid for steel pickling, chemical synthesis, oil-well acidising and pH adjustment in water-treatment systems.

Buyers in Iraq, the Kurdistan Region, Afghanistan, Uzbekistan, Jordan, Oman, Syria, Russia, Georgia, Armenia and the Persian Gulf countries source this Iranian acid for continuous industrial processes that cannot tolerate supply gaps.
