DDP is the most requested Incoterm from first-time importers and the most misunderstood one. Each of the five items below is a belief that is reasonable, common, and wrong in a specific way.
References are to Incoterms 2020, where DDP is the only rule that places import clearance and duty on the seller.

None of the five is an argument against DDP. DDP is often the correct term. It is simply the term that gets chosen for the least examined reason, and the cost of that shows up months later rather than at booking.
1. DDP means the seller pays everything, so I have no cost risk
Under Incoterms 2020, DDP does place import clearance, duty and taxes on the seller. What it does not do is make those costs disappear.
The duty is a function of the HTS classification, the country of origin and the declared value. All three are known before the goods ship. A seller quoting DDP has priced them in, which means the buyer is paying them with a margin attached and without seeing the line item.
The practical test: ask the seller to state the duty component separately. A seller who can do that is quoting carefully. One who cannot is guessing, and a guess that turns out low becomes a renegotiation at the worst possible moment.
2. DDP means I am not the importer of record
Incoterms allocate cost and risk between buyer and seller. They do not change who CBP holds responsible.
The importer of record is the party named on the entry. Under DDP that is frequently the seller's appointed agent, but it can be the buyer, and in either case CBP's five-year recordkeeping obligation attaches to the name on the entry, not to the commercial contract.
This matters most after the fact. When a valuation or classification question is raised months later, the party CBP contacts is the one on the entry. Ask who is being named before the first shipment, in writing.
3. DDP is always more expensive than DAP or FOB
It depends on who can clear more cheaply, and on whether the buyer can clear at all.
A buyer without a continuous bond, without an HTS classification for the goods, or without volume enough to negotiate inland rates is paying a broker to build all of that from scratch. A seller moving containers weekly already has it, and the difference can exceed the margin added to a DDP quote.
The comparison is only fair when both parties are priced to the same point. Convert DAP to a door cost by adding brokerage, bond, duty administration and the inland leg, then compare.
4. The duty in a DDP quote is fixed once agreed
Duty is calculated at entry, and three inputs move between quotation and entry.
The HTS classification can change on review. The rate schedule can change by policy while the goods are on the water. The declared value moves with the exchange rate and with which elements of the transaction CBP accepts as part of the price paid or payable.
A DDP contract that is silent on this is a contract with an unpriced variable. The sentence that resolves it is short: duty changes taking effect after the contract date are borne by whichever party the contract names, and it should be named before the first booking.
5. Once the goods are delivered, DDP ends my exposure
Risk transfers on delivery. Recordkeeping and the liability that attaches to it do not.
Entry records must be retained for five years from the date of entry, and that obligation follows the importer of record. A classification or valuation issue identified in year three is still a live issue in year three.
It also does not end the practical exposure. A container delivered late under DDP still arrived late, and the commercial consequence of that sits with the buyer regardless of which Incoterm was used.
What a buyer can do about it is limited but not nothing: ask who is named as importer of record, ask where the entry records will be held, and ask what happens to those records if the supplier relationship ends. Three questions, asked before the first booking, are the difference between a term that was chosen and a term that happened.
DDP is a good term used for a bad reason. It is the right choice when the buyer cannot clear efficiently; it is the wrong choice when it is being used to avoid learning what the duty actually is.
