Buyers ask this question expecting a single answer, usually phrased as “isn’t DDP cheaper because it’s one price?” The honest answer is that a correctly priced DDP quote and a correctly priced FOB shipment land within roughly 5–15% of each other. The real difference is not the money. It is who holds the customs relationship, who carries the working capital for 4–8 weeks, and who absorbs the risk when a duty rate or a port fee moves.
That difference decides which term is cheaper for you, and it depends on things a supplier cannot know: whether you have a customs bond, whether anyone on your team can clear an entry, and how much volume you ship per year.
What each term actually covers
| Cost line | FOB (you arrange) | DDP (supplier arranges) |
|---|---|---|
| Factory to origin port | Supplier | Supplier |
| Export customs clearance | Supplier | Supplier |
| Ocean or air freight | You | Supplier |
| Marine insurance | You | Supplier |
| Import customs entry & duty | You | Supplier |
| Destination port charges | You | Supplier |
| Inland delivery to your door | You | Supplier |
| Destination sales / use tax | You | You — DDP does not cover it |
Under Incoterms 2020, DDP is the only rule where the seller clears the goods for import. That single sentence is where most of the complexity lives.
Volumetric weight: why a light carton pays on volume
Packaging is mostly air. A carton of rigid gift boxes can weigh 120 kg and occupy 2.5 CBM, and the carrier will not charge you for the 120 kg. Both air and LCL sea freight are billed on the greater of actual weight or volumetric weight, and the conversion factors differ by mode:
| Mode | Volumetric factor | 1 CBM equals | Worked example |
|---|---|---|---|
| LCL sea (W/M) | 1 CBM = 1,000 kg | 1,000 kg | 2.5 CBM is charged as 2,500 kg even if it weighs 120 kg |
| Air freight | 1 CBM = 167 kg (6,000 cm³/kg) | 167 kg | 2.5 CBM is charged as 417.5 kg |
| Express courier | L × W × H (cm) ÷ 5,000 | 200 kg | A 60 × 40 × 40 cm carton is charged as 19.2 kg |
The practical consequence: anything you can do to reduce packed volume moves your landed cost more than shaving weight. Flat-packing cartons, nesting rigid boxes, removing unnecessary void fill and choosing a pallet pattern that loads the container tighter are freight savings disguised as packaging decisions. This is also why the same 5,000 boxes priced two ways — assembled and flat — can differ by a full freight tier.
Ask your supplier for the export carton dimensions and the CBM per master carton at the quoting stage, not after the order. A factory-direct quote that gives you CBM is a quote you can cost end to end; one that only gives you pieces and weight is missing the number that decides the freight.
The costs buyers forget when comparing
When a buyer compares a DDP quote against an FOB quote plus a forwarder estimate, three lines are usually missing:
- Destination charges — terminal handling, documentation and chassis fees at the receiving port are billed to whoever is the consignee. On small shipments these can exceed the ocean freight itself.
- Customs brokerage and entry filing — a broker fee per entry, plus the filing itself, plus a possible bond fee if you do not hold a continuous bond.
- Cash-flow cost — under FOB you pay freight, duty and delivery upfront and reclaim nothing; under DDP it is one invoice on the supplier’s schedule. On a $30,000 shipment that timing difference is real money even at modest interest rates.
There is also an asymmetry people rarely price: duty is calculated on CIF value, not on the goods value alone. Under FOB the freight you choose changes your duty base. Under DDP the supplier controls it.
The surcharges that appear after the quote
Ocean freight rates move, and a large part of the movement is surcharges that sit outside the base rate. Knowing their names is how you read a quote without being surprised at the port:
| Surcharge | What it covers | Who typically pays |
|---|---|---|
| BAF / CAF (bunker / currency adjustment) | Fuel and currency movement | Whoever books the freight |
| PSS / GRI (peak season / general rate increase) | Seasonal capacity | Whoever books the freight |
| LSS (low-sulphur surcharge) | IMO 2020 fuel compliance | Whoever books the freight |
| Origin THC / destination THC | Terminal handling at each end | Depends on the term — DDP folds both into the price |
| Documentation / telex release | B/L and release fees | Consignee, unless DDP |
| AMS / ISF (US) or ENS (EU) filing | Advance cargo security filing | Importer of record |
| Chassis and port congestion | Equipment and terminal delay | Consignee |
| Demurrage / detention | Container held at port or off-port past free time | Consignee — the single most avoidable charge |
| Customs exam | Physical or X-ray inspection | Importer of record |
Two habits keep these from becoming surprises. First, ask whether each quote is all-in or plus-surcharges — an FOB rate quoted “plus BAF/LSS” is not comparable to a DDP price that already includes them. Second, plan the free-time: demurrage and detention are the charges buyers pay for their own delay, and they are entirely within your control.
Who can legally be the importer of record
This is the part that decides whether DDP is even available to you.
For a commercial import into the United States, the importer of record must be a US entity — or a foreign entity with a US presence — and must post a customs bond. A Chinese manufacturer cannot be the IOR on a US commercial entry in its own name.
So a “DDP to the US” quote is normally structured one of three ways:
- A partner IOR service — the supplier engages a US-based importer-of-record service which takes legal responsibility for the entry. Common for small and mid-sized buyers without a bond.
- You remain the IOR while the supplier covers the cost — the commercial term is DDP but the customs liability is yours. Most suppliers doing business with established US buyers use this structure.
- A US subsidiary of the supplier acts as IOR — only available when the supplier actually has a US legal entity.
Whatever the structure, ask your supplier to name the importer of record on the quote in writing. If nobody can answer that question, the DDP price is not a DDP price yet — it is an estimate that will be renegotiated at the port.
This is also why DDP is generally simpler for the EU, the UK, Japan and Australia than for the US: those jurisdictions impose fewer restrictions on who may act as the importer.
Indicative ocean transit times from South China
Transit time decides how much safety stock you carry, so it belongs in the landed cost, not only in the logistics plan. Port-to-port transit from Yantian or Shekou (Shenzhen) typically runs as follows. These are port-to-port sailing times, not door-to-door — add 5–10 days at each end for booking, customs and inland delivery, and add a week or more during the pre-Lunar-New-Year peak.
| Destination port | Region | Indicative transit (days) |
|---|---|---|
| Los Angeles / Long Beach | US West Coast | 14–18 |
| New York / Savannah | US East Coast (via Panama) | 28–35 |
| Vancouver | Canada West Coast | 15–19 |
| Rotterdam | Northern Europe | 28–33 |
| Hamburg | Northern Europe | 30–35 |
| Felixstowe | UK | 30–36 |
| Jebel Ali | Middle East | 18–24 |
| Sydney / Melbourne | Australia | 16–22 |
| Tokyo / Yokohama | Japan | 5–8 |
| Singapore | Southeast Asia | 4–7 |
For a first order, build the plan backwards from your in-store date: mass production lead time, plus booking and sailing, plus destination clearance and delivery, plus a buffer. If the total does not fit, the answer is usually to move the order earlier rather than to pay for air freight — unless the cartons are small enough that volumetric weight makes air viable.
A worked comparison
Indicative figures for a mid-sized shipment — 12 CBM, 850 kg, goods value $18,000, sea freight from Yantian to a US East Coast port plus inland delivery. Duty is left as a variable because rates depend on your HS code and current trade measures.
| Line | FOB (you pay) | DDP (supplier pays) |
|---|---|---|
| Goods | $18,000 | (in the DDP price) |
| Origin charges | included in goods price | included |
| Ocean freight (LCL) | $1,200–1,700 | included |
| Marine insurance | $60–90 | included |
| Destination port charges | $300–500 | included |
| Brokerage + entry filing | $150–300 | included |
| Duty | variable — see below | included |
| Inland delivery | $300–700 | included |
| Arranged-by-you total | $20,010–21,290 + duty | one invoice |
If the supplier’s DDP price comes in at $21,500–23,000 including duty, the two routes are close, and DDP is buying you three things FOB does not: no customs bond requirement, no entry filing work, and no freight coordination. For a buyer shipping two shipments a year, that is usually worth more than the delta.
Duty is the unstable variable
Duty is where DDP quotes get uncomfortable, on both sides:
- Rates depend on the HS code, which is assigned to the goods’ classification — packaging is not one code. Paper boxes, printed matter, bags and labels sit in different chapters.
- Trade measures change. Between 2025 and 2026 alone, several jurisdictions adjusted tariff treatment repeatedly, and de minimis thresholds also changed. Any DDP quote that names a firm duty rate six months in advance is guessing.
- A DDP quote should state whether duty is included at a fixed rate, passed through at cost, or excluded. All three exist in the market; they are not equivalent.
Ask for the wording. A supplier confident in their numbers will put the duty treatment in writing; one who will not is passing the risk back to you at the port.
Which term should you choose?
| Your situation | Recommended term | Why |
|---|---|---|
| First import, no customs bond, no broker | DDP | Removes the entry filing and bond requirement entirely |
| Under 5 CBM per shipment | DDP | Destination charges and brokerage overwhelm the freight saving on small volumes |
| Shipping monthly, 10+ CBM, have a broker | FOB | You have the volume leverage and the relationships — FOB keeps the margin |
| You need to control HS classification | FOB | Duty engineering depends on you owning the entry |
| Your finance team cannot hold 4–8 weeks of extra working capital | DDP | One invoice, on the supplier’s credit terms |
| You want a genuine total landed cost number for budgeting | DDP as a benchmark | Even if you ship FOB, get a DDP quote to sanity-check your forwarder |
A practical habit worth adopting: get both quotes on the same order, every time. The comparison takes your supplier five minutes, and it is the only reliable way to know which one your forwarder is actually beating. Freight is only the last step of the number — for how the packaging price itself is built up before carriage is added, see what drives custom packaging cost, and for how order size changes the unit price, see MOQ effects on packaging price.
For how we structure delivered-duty-paid shipping from Dongguan — including what the quote covers and what it excludes — see DDP door-to-door shipping. If you would rather compare the two routes on your own SKUs, send us the carton dimensions and destination and we will price both.
At Zhengyang Packaging (packpert.com), DDP is quoted as one delivered cost to your door across North America and Europe, with customs clearance and duty handled on our side; we quote the FOB Dongguan alternative on the same order, on identical carton dimensions, so the comparison is like-for-like rather than an estimate.
