According to WPB, rising petroleum-bitumen imports through Khorgos are drawing attention to China’s overland supply options. Customs statistics put arrivals through the China–Kazakhstan gateway at approximately 49,000 metric tons during the first nine months of 2026, an increase of 176.5% from the same period a year earlier. The figures confirm growing activity at the crossing, but do not disclose the cargo’s origins or distinguish truck deliveries from rail shipments. They therefore cannot establish Iran’s share or identify the busiest gateway for Iranian bitumen.
For Iranian exporters, the commercial question extends beyond whether a route exists. The shipment must reach a specific Chinese buyer at a competitive total cost, using equipment and documentation accepted throughout the journey. WPB’s assessment identifies road and rail corridors through Central Asia and an option combining trucking and sea transport through Turkey. Any Oman relay requires separate verification of the customs procedure and handling location, particularly for shipments affected by the November 1 changes. Available information does not yet provide a verified, comprehensive freight rate that would establish the profitability of any one route for a defined Iranian bitumen shipment.
One road option runs east from Iran through Sarakhs into Turkmenistan, continues through Uzbekistan and Kazakhstan, and enters China at Khorgos. Current China–Iran trucking services identify this crossing as a principal gateway within their own networks. A southern alternative passes through Turkmenistan, Uzbekistan and Kyrgyzstan before reaching China at Irkeshtam. The existence of these services supports further commercial investigation, although general cargo operations do not automatically establish acceptance, pricing or capacity for Iranian petroleum bitumen.
The operating plan matters as much as the country sequence. TIR procedures and advance cargo declarations can facilitate customs transit, while the actual movement may still involve changes of tractor, trailer or container. Before dispatch, the exporter needs to know where any transfer will occur, who handles the cargo and how waiting time is charged. Net payload and packaging must also be fixed at the quotation stage because drums, caged jumbo bags and heated bulk shipments require different arrangements.
The buyer’s location can materially change the comparison. In WPB’s assessment, trucking deserves closer examination for customers in Xinjiang, where a western border entry could offer an alternative to importing through a coastal port and then transporting the product inland. The same reasoning cannot be applied without adjustment to a buyer in Guangzhou or Ningbo. A price ending at Khorgos leaves a different onward transport obligation from a quotation covering delivery to a coastal Chinese customer.
Current product assessments show the importance of controlling those additional costs. In the third week of October, WPB assessed Iranian 60/70 drum bitumen at $383 ±5 per metric ton EXW factory, while its Chinese assessment for the same grade and packing stood at $708 ±5 per metric ton CFR Nansha and Guangzhou. These figures describe separate market assessments with different delivery obligations. They are not a matched purchase and resale transaction from which a transport margin can be established.
A meaningful profitability calculation must begin with the actual purchase price and the buyer’s agreed delivery point. It then needs to include collection in Iran, transit charges, border services, handling, freight, insurance, financing and any inspection or waiting costs. Import clearance, duties, applicable taxes and delivery within China must be treated consistently across the alternatives. Subtracting an Iranian factory assessment from a Chinese port assessment would leave too many of those obligations unresolved.
Rail offers a more developed planning structure for containerized Iranian bitumen. Under the arrangements announced at Aprin Dry Port in September, petroleum bitumen classified under HS 271320 can be received for terminal handling and onward rail preparation after export formalities have been completed at an authorized customs location. The separate procedure for direct export of natural bitumen under HS 271490 does not establish the same treatment for petroleum bitumen. Exporters must therefore settle product classification and customs routing before sending cargo to the terminal.
A published commercial proposal links Aprin with Xi’an using one-metric-ton jumbo bags supported by steel cages inside containers. That model targets block-train quantities and places responsibility for rail freight and container arrangements with the buyer or its nominated forwarder. It gives exporters a basis for requesting a detailed offer, although it does not establish a fixed freight tariff or a regular record of completed petroleum-bitumen deliveries on the proposed service.
The northern rail option connects Aprin with Incheh Borun, Turkmenistan and Kazakhstan before reaching China’s rail gateways. Another routing uses Sarakhs and the Central Asian network. A China-to-Iran block train launched in September followed Kazakhstan, Uzbekistan and Turkmenistan toward Sarakhs, carrying general cargo and automotive components. Its launch demonstrates use of the corridor in the opposite direction; eastbound bitumen still requires its own booking, cargo approval and rate confirmation.
Rail handling also deserves close attention. The route crosses between the standard-gauge systems used in Iran and China and the broad-gauge networks of Central Asia. Depending on the service, containers or rail equipment must be transferred at the relevant interfaces. This does not necessarily require opening the containers or repacking the bitumen, but terminal availability and transfer queues can affect the delivery schedule and final bill.
The China–Kyrgyzstan–Uzbekistan railway should remain outside a current shipment calculation. Construction was continuing in September, despite progress on the project’s first tunnel in Kyrgyzstan. Exporters considering access through that region need to distinguish the existing road option at Irkeshtam from the railway still being built.
Turkey presents a different commercial proposition. Cargo could leave Iran through Bazargan–Gürbulak, travel by truck to Mersin or Iskenderun, and continue to China by sea. This sends the product west before the maritime leg takes it east, so the complete chain needs to justify the additional land distance, border crossing and port operations. Its value would depend on the combination of an acceptable trucking rate and a confirmed ocean booking.
Published selling indications provide reference points for that comparison. On October 23, new-drum 60/70 bitumen was listed at $570–580 per metric ton FOB Iskenderun. Separate commercial indications for shipment from Turkish ports placed 60/70 supply at $688–728 per metric ton CFR Nansha or Guangzhou. Those figures describe offered product prices; they do not establish the freight payable for a particular Iranian cargo moving through Turkey.
The Turkish option consequently requires a quotation that clearly separates the product price from logistics charges. The comparison must also establish which handling and loading costs are already included so that they are counted only once. The ocean booking must explicitly cover Iranian-origin cargo, with the production origin and Turkish loading port clearly distinguished in the transaction documents. Border waiting, storage and financing can also affect whether an apparently competitive offer remains attractive when delivered.
Pakistan could theoretically provide access to China either through its seaports or through the road crossing at Khunjerab. The maritime version would involve moving cargo toward Karachi, Port Qasim or Gwadar before loading it for China. The northern version would require road transit through Pakistan toward Xinjiang. Demonstrated China–Pakistan TIR movements do not, by themselves, confirm that a specific Iranian bitumen shipment can currently complete either journey.
Recent border conditions make that distinction particularly important. By October 23, Gabd–Rimdan was allowing some Pakistani perishable exports to resume following closures there and at Taftan, while Iranian LPG movements remained interrupted. Those developments do not establish the clearance position for petroleum bitumen. A usable Pakistan quotation must therefore include confirmation of current border access and permission for the proposed transit movement.
Oman requires a more specific operational assessment following Trade Circular No. 4/2026, dated October 20. From November 1, 2026, until further notice, Port Sultan Qaboos and Port of Suwaiq will cease providing cross-stuffing services for re-export. Stuffing and unstuffing of import and export containers are retained, while cross-stuffing for re-export is redirected to Khazaen Dry Port, described in the circular as a bonded station equipped for that service.
Cross-stuffing involves moving cargo between containers or between a container and a truck. It should be distinguished from transferring an intact container between vessels under a transshipment arrangement. The circular changes the location of a particular handling service at two named ports; it does not announce a nationwide suspension of all Omani imports, exports or transshipment.
Sohar is not named in this circular, so the document cannot establish that all operations there have stopped. Equally, it does not authorize a particular Iran–Sohar–China shipment. Exporters must separately confirm the applicable customs procedure, whether container transfer is required, the location permitted to carry out that work, and carrier acceptance of Iranian-origin cargo. A product quotation on FOB Sohar terms does not establish approval for transshipment or cross-stuffing.
Any proposed use of Khazaen also requires confirmation that the specific bitumen cargo and intended customs movement can be accepted. The cost comparison must include freight from Iran to Oman and onward to China, together with any authorized inland movement, container handling, storage, waiting and financing. WPB therefore treats Oman as a conditional option requiring documented customs and operational confirmation, with no established cost advantage over comparable routes.
The practical decision should come from competing quotations for one defined shipment. Road transport through Khorgos, rail from Aprin and a feasible maritime combination need to be priced against the same grade, packing, net tonnage, shipment window and Chinese delivery address. Each offer should identify its transfer points, customs responsibilities, insurance scope, waiting charges and validity.
WPB’s assessment is that western Chinese destinations provide a reason to investigate direct trucking, while larger containerized orders warrant a detailed rail comparison. Turkey requires confirmation of the road and maritime stages; Oman requires confirmation of the specific customs procedure and authorized handling location; and Pakistan requires clearer assurance on border access. Khorgos’s growing bitumen imports strengthen the evidence for an active land gateway, but a competitive Iranian export opportunity will ultimately depend on the complete delivered cost agreed for the buyer’s actual location.
