Pakistan's border crossings with Iran at Gabd-Rimdan and Taftan — suspended on October 17 citing security risks — have partially reopened, with pre-dated cargo clearing and some Pakistani exports moving again. But the resumption is selective and slow, and the mechanisms blocking Iranian imports remain firmly in place. The surface narrative is security. Balochistan province recorded 131 of 225 armed attacks nationwide in September, the highest monthly national total in 12 years. Gunmen attacked trucks near the Gabd crossing on October 17, and the military reported killing 10 attackers in subsequent operations around Gabd and Gwadar city, with one civilian dead. Deputy Commissioner of Chagai Bakhtiar Ismail called the closure a temporary measure for border management and counterterrorism. But the deeper mechanics point elsewhere. On October 16, Pakistan's Commerce Ministry withdrew a waiver on the E-Form (EIF) requirement for Iranian imports — a banking-linked document that records imports and their payment through banks. Iran's ambassador Reza Amiri Moghadam said publicly that Iran placed no restrictions on exports to Pakistan and that the E-Form change had effectively made it impossible for traders to dispatch cargo from Iran. Several hundred LPG trucks reportedly crossed into Gabd but remained unloaded and uncleared. Balochistan Goods Truck Owners Association president Haji Noor Muhammad Shahwani confirmed the unloading problem was unresolved and pointed to banking-system complications. The LPG stoppage is not an abstraction. Pakistan imports the bulk of its energy from the Middle East, and Iranian LPG is a critical supply line. The halt created immediate shortages and price spikes domestically. This comes on top of shipping disruptions in the Strait of Hormuz from the US-Israel war on Iran, which has already battered Pakistan's economy. The sanctions question looms over everything. The US has imposed a naval blockade on Iranian ports and wide-ranging economic sanctions designed to, in Washington's own language, "asphyxiate" the Iranian government. Pakistan has been mediating between Washington and Tehran since the conflict began February 28. Pakistan's Foreign Ministry spokesman stated that Pakistan "adheres to and shall continue to adhere to all applicable sanctions regimes" — a careful formulation that neither confirms nor denies US pressure on the border closure. The Ministry of Commerce did not respond to Al Jazeera's inquiries. Security analyst Imtiaz Baloch offered the most honest assessment: US maximum-pressure policy has direct or indirect influence, whether through forcing Pakistan's government to close the border or through leverage over companies in the LPG trade and international banking channels. His read — security, procedural glitches, and banking-system pressure are all operating simultaneously — captures the layered nature of the chokepoint. No single explanation is sufficient, and the ambiguity itself is the tool. What is emerging is a pattern where administrative and procedural mechanisms — paperwork requirements, banking compliance, customs processing — serve as deniable enforcement tools for geopolitical pressure. Pakistani rice and bananas flow out; Iranian LPG stays stuck. The asymmetry is the signal.
