Tofiq Daru Company

The IDF struck the Tofiq Daru pharmaceutical factory in Tehran on Day 30 of the Iran conflict, claiming the company had supplied fentanyl for chemical weapons research. No independent verification of the chemical-weapons claim has been published. The strike drew immediate international attention because pharmaceutical facilities receive special status under the Geneva Conventions, and the dual-use allegation is contested.

Tofiq Daru is a mid-sized Iranian pharmaceutical manufacturer. Iran's pharmaceutical sector operates under US Treasury sanctions carve-outs that nominally protect medicines and medical equipment; however, dual-use production allegations have been used previously by the US and Israel to justify strikes on facilities otherwise shielded by humanitarian law. Fentanyl is a controlled opioid with legitimate medical applications and potential for weaponisation as a chemical incapacitant.

The strike is notable as part of a pattern in Day 30's targeting alongside the second strike on Mobarakeh Steel. Both events signal an expansion of the target set beyond military and nuclear infrastructure into dual-use civilian industry, raising questions about proportionality and the legal basis under International humanitarian law.
