Why three quotes for the same shipment come back three different prices
Send the same carton details to three forwarders and you can get quotes that differ by 50% or more. That spread is rarely about one company being greedy. It is usually about the three quotes measuring different things: different chargeable weights, different sets of included costs, and different assumptions about who pays the UK tax. Comparing the headline numbers without checking the basis is how buyers end up paying more than the cheapest quote suggested.
This page shows the five lines that decide the real difference between quotes on the China to UK lane, and how to pull three quotes onto the same basis so the comparison actually means something.
The five lines that decide what you actually pay
Every China to UK quote is a combination of the same five lines. The differences between quotes live in how each line is calculated and whether it is included at all:
- Chargeable weight. Air quotes bill on the higher of actual and volumetric weight. If two forwarders use different formulas or different carton measurements, the kg base differs before anything else is priced.
- Incoterm. EXW, FOB, DAP, and DDP put the cost and risk at different points. A DAP quote and a DDP quote for the same goods are not the same price and never should be.
- Duty and VAT. UK import VAT at 20% is a large line on most shipments. A quote that leaves it out looks cheaper and arrives with a bill.
- Clearance and handling. The customs filing, broker fees, and port or airport handling. On sea freight this is where the destination charges hide.
- UK delivery. The last leg from the port or airport to your door, priced by distance on freight shipments.
Two quotes that state the same chargeable weight, the same Incoterm, and the same included lines are comparable. Anything less is apples and oranges, however close the numbers look.
The cheap-quote tricks that cost you later
Low quotes tend to share one of three structures:
- The DAP quote sold as a bargain. It looks cheaper than the DDP price, but the duty, VAT, and clearance arrive as a separate bill at the UK border, often larger than the saving.
- The light chargeable weight. The quote prices your actual weight and quietly ignores the volumetric formula, so the billed kg at departure is higher than the quoted kg.
- The per-kg rate with everything else on top. The headline rate is low, and fuel, clearance, handling, and delivery are added as surcharges at the end, which is how a cheap rate becomes an expensive invoice.
None of these are scams. They are quotes that answer fewer questions than you asked. The defence is the same in each case: demand the five lines above in writing before comparing.
Putting three quotes on the same basis, with numbers
Take a worked example: 200 kg of goods in cartons with a chargeable weight of 240 kg, flying from Shenzhen to a Manchester address. Quote A shows GBP 3.10 per kg, DAP, nothing else. Quote B shows GBP 4.60 per kg, DDP, all in. Quote C shows GBP 3.40 per kg with fuel and clearance added later.
Quote A: GBP 744 for freight, then import VAT at 20% on the goods value plus freight plus duty, plus a clearance fee. On a GBP 4,000 goods value that VAT alone is around GBP 950, and clearance and delivery add another couple of hundred. The real total is in the region of GBP 1,900.
Quote B: GBP 4.60 x 240 kg = GBP 1,104, all in, nothing more to pay. Quote C: GBP 3.40 x 240 kg = GBP 816, then fuel, clearance, VAT, and delivery land on top, ending close to quote A.
The cheapest headline rate, quote A, becomes the most expensive total once the VAT and clearance are added. That is the entire problem with comparing per-kg rates on the UK lane, and the reason the all-in number is the only one worth comparing. The DDP cost calculator reproduces this arithmetic for your own shipment, line by line.
What to send a forwarder so the quotes come back comparable
Quotes differ because the inputs differ. Standardise the inputs and the quotes converge. Send every forwarder the same five details:
- Carton count, weight, and outer dimensions, so chargeable weight is computed the same way.
- The HS code and declared goods value, so duty and VAT can be estimated.
- The origin city in China and the destination postcode in the UK.
- The Incoterm you want, stated as DAP or DDP.
- Any special handling, such as batteries or liquids, which changes both the rate and the channels available.
With identical inputs, three honest forwarders land within a reasonable band of each other. A quote far outside that band is either including different things or planning to add them later.
Beyond the price: what the quote does not say
The lowest all-in quote is not automatically the best shipment. Ask what happens when things go wrong: whether the transit time is committed in writing, how damage or loss is compensated, and who answers when a customs query lands. A forwarder that prices 3% higher but answers in hours and carries insurance is cheaper than a forwarder that saves you GBP 50 and disappears when the container is delayed. The vetting side of this is covered in our China to UK freight forwarder guide.
Frequently asked questions
Why do shipping quotes from China to the UK differ so much?
Because they measure different things: different chargeable weights, different Incoterms, and different sets of included costs. VAT and clearance are the biggest variables. Compare all-in DDP numbers, not per-kg rates.
Should I take the cheapest shipping quote?
Not automatically. A low quote usually excludes VAT, clearance, or the volumetric weight, and the bill arrives later. Check what the price includes before trusting it.
Is DDP shipping always more expensive than DAP?
DDP looks more expensive on paper because the duty, VAT, and clearance are inside the price. Once those are added to a DAP quote, the totals are usually close, with DDP carrying the risk.
What should a shipping quote from China to the UK include?
Chargeable weight basis, Incoterm, duty and VAT treatment, clearance and handling, and UK delivery. If any of those five lines is missing, ask for it before comparing.
How do I get an accurate quote from China to the UK?
Send the same carton weights, dimensions, HS code, declared value, origin city, and UK postcode to three forwarders, request all-in DDP prices, and compare them line by line.
