Iran requires ISIRI 9117 marking on every flange. Most refineries (Abadan, Isfahan, Bandar Abbas) operate on ASME B16.5 with materials A105, A350 LF2, F316L. PED & EN 1092-1 also common due to European process licensors.
Bandar Abbas (primary) or Imam Khomeini Port (formerly Bandar-e Emam). 14-20 days from Shanghai via Strait of Hormuz. Banking: euro/rial via third-country correspondent (UAE, Turkey) is the norm; JPY and CNY direct settlement available.
TT 30% advance + 70% against B/L copy is standard. LC at sight from Iranian banks (Bank Melli, Saderat, Mellat) accepted with reasonable confirming bank. Some buyers prefer CAD (cash against documents) for repeat orders.
