Sahlan Special Economic Zone matters in the Hormuz Graph as a rail- and road-linked logistics platform near Tabriz, one of Iran’s most important northwest industrial and trade cities. Its role connects warehousing, customs-sensitive movement, rail freight, road distribution, and access toward Turkey, the Caucasus, and the Aras corridor. The asset is distinct from Maku and Aras because it is more directly tied to Tabriz’s manufacturing base, inland logistics, and regional redistribution rather than being primarily a border or free-zone platform.
