When you order iPhone parts from Shenzhen, the shipping quote comes with a choice that changes your real cost by 10-30%: DDP or DDU terms. Many shop owners pick on sticker price alone and get surprised at customs. This comparison breaks down what each term actually does to your landed cost, your paperwork, and your risk.
What the Terms Mean in Practice
DDP (Delivered Duty Paid): the seller or their freight agent handles customs clearance and pays duties and taxes. The parcel arrives at your door with nothing left to pay.
DDU (Delivered Duty Unpaid): the parcel arrives in your country and the customs process lands on you - either self-clearing or through a broker, paying duties and any handling fees before release.
The Real Cost Comparison
| Factor | DDP | DDU |
|---|---|---|
| Quoted shipping price | Higher - duties baked in | Lower on paper |
| Your customs paperwork | None | Full - invoice, HS codes, declarations |
| Customs delay risk | Carrier's agent manages it | Yours - a stuck parcel waits on your forms |
| Cost predictability | Locked at order time | Variable - broker fees and assessments at arrival |
| Best for | Small shops, first orders, urgent repairs stock | Experienced importers with brokers, high volume |
When DDP Wins
If you import a few parcels per month and do not hold a customs broker relationship, DDP usually nets out cheaper per unit of hassle. Your supplier's agent clears in bulk daily and absorbs the process cost. The premiums are already priced into their freight contracts. For trial orders and urgent restocks, DDP also removes the single biggest schedule risk: a parcel held at customs while your repair bench waits.
Ask your supplier exactly how they DDP: legitimate agents declare the goods properly with correct HS codes - our invoicing and HS code guide explains what correct paperwork looks like. Grey-channel DDP that under-declares creates risk that lands on you as the importer of record.
When DDU Wins
DDU rewards structure. If you ship weekly, register as a formal importer, and use a broker, self-clearing typically costs less than DDP premiums - especially into markets where your duty rate on phone parts is low. You also gain visibility: your own entries, your own valuation history, fewer surprises. The trade is administrative time and the requirement to keep clean commercial invoices - our customs clearance checklist covers the document set.
The Decision Rule
- Under 2-3 shipments a month, no broker: DDP.
- Regular volume, broker relationship, low duty market: DDU and keep the margin.
- Mixed: DDP for urgent and trial parcels, DDU for planned bulk moves - many shops run both in parallel.
Whichever you choose, the freight comparison only matters if the parts arrive grade-true; our receiving QC checklist keeps that side honest.
FAQ
Does DDP mean no import tax exists? No - the tax exists and someone paid it; DDP just means it was handled before the parcel reached you.
Can DDP parcels still be held at customs? Rarely, for inspections - but the agent manages the process, not you.
Is DDU the same as DAP? Nearly - DAP makes delivery-point obligations explicit. For shop purposes, treat the paperwork burden as the same.
