Urgent orders, small consignments and over-dimension pieces on the Iran lane often end up moving by road, because a truck runs door to door without a gauge change. The advantage is real, but the clearance steps are no fewer than on the railway; they are simply arranged differently. This article follows a road FTL shipment through its three legs, exit at Khorgos, transit across Central Asia and entry through Incheh Borun, then compares the clearance steps with rail FCL and covers what out-of-gauge and dangerous goods add.
1. What road FTL is good for
Road FTL puts the goods on a single truck that carries them straight to the delivery point without consolidating with other cargo. It is fast and flexible: there is no gauge change, no dependence on a fixed train schedule, and one vehicle covers the door-to-door move. The cost is a higher rate per tonne than rail or sea.
The cargo profile follows from that. Road suits urgent orders with a hard delivery date, mid-size consignments from a few hundred kilograms to roughly a dozen tonnes, pieces that exceed normal container limits, and project cargo where the dispatch date has to stay flexible. The route and vehicle types are described under China to Iran road freight (FTL). When you are weighing road against rail, it is worth reading the two together; the rail alternative is set out under China to Iran rail freight (FCL).
The journey divides into three legs, each with its own operations and documents.
| Leg | Main operations | Key documents |
|---|---|---|
| Exit at Khorgos | Loading, export declaration, border release | Customs declaration, packing list, invoice, contract, road waybill |
| Transit across Central Asia | Transit declaration, movement under customs control | TIR carnet, transit declaration |
| Entry at Incheh Borun | Entry declaration, inspection, release | Import permit, certificate of origin, entry declaration |
2. Leg one: exit at Khorgos
Khorgos is the main exit for road FTL. Three things happen here. The first is vehicle assembly and loading, with the cargo secured at the designated yard. The second is the export declaration, filed per vehicle by the broker. The third is border release, after which the customs check is cleared and the vehicle leaves the country.
The documents for this leg are in the table above, plus the driver and vehicle papers. Road freight is declared per vehicle, so one truck corresponds to one set of documents; if the cargo changes, the file has to be updated at the same time. A vehicle whose manifest and load disagree at the border will be pulled aside, and that delay is entirely avoidable.
3. Leg two: transit across Central Asia
After Khorgos the vehicle enters the transit leg, normally through Kazakhstan and then, depending on the routing, through Uzbekistan and Turkmenistan. The core of this leg is the transit declaration, made under a TIR carnet, with the vehicle moving under customs control and, as a rule, no unloading on the way.
The risk sits in the border conditions of the transit countries and in how well the documents connect. If the declaration at any transit point does not match the cargo actually carried, the vehicle can be held for inspection. The description, piece count and weight have to stay identical from the exit declaration to entry, with no adding or swapping of cargo in between.
4. Leg three: entry at Incheh Borun
The last leg before Iran is the entry declaration at Incheh Borun. When the vehicle reaches the crossing, the broker on the Iranian side files the entry declaration per vehicle; customs check the documents, open the load if needed, and release once the duty is settled. The vehicle then runs on to its destination inside Iran.
Incheh Borun handles both rail and road entry, so when work is concentrated the vehicle queue lengthens and clearance time grows. The live operations and common questions for the crossing are on the Incheh Borun border page. The entry documents mirror the exit set, so the import permit and certificate of origin have to be aligned at both ends well before the truck arrives.
5. Rail FCL versus road FTL: the clearance steps
Both are China–Iran routes, but the two modes divide the clearance work differently. The table aligns the steps.
| Clearance step | Rail FCL | Road FTL |
|---|---|---|
| Declaration unit | Per wagon or per container | Per vehicle |
| Transhipment | Wide gauge to standard gauge | None, one truck throughout |
| Transit method | Moves with the wagon | Country by country under a TIR carnet |
| Entry declaration | Filed in a block on arrival | Filed at the border, per vehicle |
| Typical door-to-door time | About 20–35 days | About 10–16 days |
The two largest differences are these: rail goes through a transhipment, road does not, and rail clears per container in a block while road clears vehicle by vehicle. The first is why rail takes longer but costs less per tonne; the second is why road is faster but carries less in one movement.
6. Out-of-gauge and dangerous goods
Over-dimension cargo adds a condition to a road move. A piece that is over-long, over-wide, over-high or over-weight usually needs an oversize transport permit in advance, a matched vehicle type, and on some sections a route survey. The closer a piece sits to, or beyond, the standard limits, the earlier the dimensions and weight should be handed to the carrier.
Dangerous goods carry a different set of requirements: the right transport qualification, a full dangerous goods file, packing that is compliant for the class, and a truthful declaration of weight and class. The documents and packing detail for lithium batteries and dangerous goods are set out in the lithium battery and dangerous goods guide. Neither category should be dispatched on a last-minute basis without a plan.

7. Frequently asked questions
How long does road FTL from China to Iran usually take?
The normal range is about 10–16 days. There is no gauge change, so the time goes mainly into the queue at Khorgos, transit declarations in Central Asia and the entry declaration at Incheh Borun, and it follows the current border status.
Which cargo suits road better than rail?
Urgent orders with a hard deadline, mid-size consignments, over-dimension pieces, and project cargo with a flexible schedule. Rail means either waiting for a train schedule or working within container limits, so road is more direct for these.
What should I watch for with out-of-gauge cargo by road?
An oversize transport permit in advance, a matched vehicle type, and a route survey on some sections. The length, width, height and weight of each piece should be reported to the carrier as early as possible.
