Ask three forwarders on the China–Iran lane who pays the import duty and you will get three different answers. DDP, delivered duty paid, is the term where that ambiguity costs the most, because the seller carries transport, export declaration, import clearance and taxes all the way to the named place. This article sets out who is responsible for what under DDP to Iran, the four points to confirm before a quote, and the three places where shipments most often go wrong.
1. What the seller actually carries under DDP
DDP sits at the heavy end of the Incoterms. The seller arranges loading at origin, the export declaration, the main carriage, import clearance in the destination country, payment of import duty and other taxes, and delivery at the agreed place. Only at the moment of delivery does risk transfer to the buyer. The buyer is left with one duty: to receive the goods at the named place.
So DDP is not the sale of a leg of freight; it is the sale of an end-to-end delivery. That is also the cleanest way to separate DDP from DAP. Under DAP the goods are delivered to the place but import clearance and taxes stay with the buyer. On this lane the difference is not academic: a rail box standing at the Iranian border still has a customs file in front of it, and someone has to be the importer of record. The door-to-door structure, the terms and the cargo classes that suit it are described on the Iran DDP door-to-door page, while the underlying main carriage is covered under China to Iran rail freight (FCL).
2. The four things to confirm before you quote
Miss any of these four and the number you quote will be revised later. Each one moves the duty base, the clearance path or the final cost.
The first is commodity and HS classification. Classification is the base of every tax calculation. Two similar goods can sit one digit apart in the tariff and carry rates that differ by several percentage points. The description has to be written precisely enough to map to a single HS code. A broad category name pushes the tax-base risk downstream, and small consignments handled as Xian to Tehran LCL are especially exposed, because the value per shipment is low and the cost of a reworked file is proportionally large.
The second is consignee eligibility and import permits. Iran requires the consignee to hold the right import qualification for a range of categories, or to obtain a permit in advance. Whether the buyer holds that qualification decides whether the goods can clear at the border at all. If the qualification is not in place, even a seller who has agreed to DDP cannot carry the obligation through, because the shipment stops at the clearance step rather than on the road.
The third is the delivery address. Delivering to a Tehran city address and delivering to an outlying industrial zone are different jobs in both cost and risk. Remotely located sites, addresses that need a second movement, or places with unusual unloading conditions should be declared early. The more specific the delivery point, the more controllable the final leg.
The fourth is whether VAT is inside the quoted tax. Import charges usually include value added tax on top of customs duty. What the phrase duty included actually covers has to be written into the quote. This single point causes more post-delivery disputes than any other item on a DDP file.
3. DDP, DAP and double-clearance: where the lines fall
The three terms are often used loosely, but the responsibilities are different. The table below aligns them on tax, clearance and the point where risk transfers.
| Item | DDP | DAP | Double-clearance (duty paid package) |
|---|---|---|---|
| Export declaration | Seller | Seller | Carrier |
| Import clearance | Seller | Buyer | Carrier |
| Duty and taxes | Borne by seller | Borne by buyer | Usually included, cap may apply |
| Risk transfer point | On delivery at destination | On unloading at destination | Per contract, usually door delivery |
| Typical use | Door delivery with duty paid | Delivered but tax unpaid | Priced package on a dedicated lane |
In one line: DDP is delivery to the door with duty paid, DAP is delivery with the tax left to the buyer, and double-clearance is a way of packaging the price. All three can appear in the same quotation, so the questions to ask before signing are the tax cap, how any excess is charged, and the exact moment risk moves.
4. The three places it usually goes wrong
The hard part of DDP is rarely the transport. It is the three boundaries below.
| Risk point | Typical cause | Action to take in advance |
|---|---|---|
| Disputed dutiable value | Declared value far from comparable goods, open to reassessment | Declare truthfully and send the contract and invoice with the goods so the price chain proves itself |
| Port or dry-port storage overrun | Clearance or collection is late and storage accrues by the day | Write the collection milestone into the contract and allow clearance buffer |
| Unclear importer of record | The buyer holds no import qualification and a third party must file | Agree in advance who appoints the entity and how the cost is shared |
The three share a pattern: the problem shows up after arrival, but the action needed sits before dispatch. A reassessment, a storage charge and an argument over the filing entity can almost all be avoided by aligning these points while the goods are still in the warehouse.
5. Keeping a DDP lane workable
DDP is not the problem; misalignment is. Four things have to be settled early: a classification that maps to a real HS code, a consignee whose qualification is confirmed, a delivery address that is specific, and a tax basis written down rather than assumed.
Get current rates and transit times
Send us the commodity, HS classification, cargo value, number of pieces, weight and dimensions, the destination and the buyer qualification status. We will return a comparison built on current rates and tax components, with a validity window, and we will spell out the tax basis and where responsibility ends so you can compare it side by side.
6. Frequently asked questions
Is DDP the same as a double-clearance duty-paid package?
No. DDP is an Incoterm that fixes the seller as the party carrying the tax and clearance obligation to the door, with risk transferring on delivery. A double-clearance package is a pricing method that bundles clearance and taxes into one figure. The two overlap in practice but are defined differently, so confirm each line before signing.
Can DDP still work if the buyer has no import licence?
It can, but the filing entity has to be agreed first. In most cases a qualified third party declares on the buyer’s behalf, and the entity, the cost sharing and the liability have to be written into the contract. Appointing that entity at the last minute slows clearance and tends to add charges.
Which line in a DDP quote is most often left vague?
The tax basis, and specifically whether VAT is included and whether a tax cap applies. One percentage point of duty on a mid-size consignment is a visible sum, so ask for the calculation method and any cap in writing rather than accepting a verbal figure.
